Introducing the StorageWorks Family
The StorageWorks family of products is a low-cost, extremely flexible mass
storage solution, that permits the user to design a StorageWorks subsystem to
meet system-specific needs. This chapter is an introduction to the StorageWorks
product line and includes a general description of the products, components, and
features.
Note
The configurations defined in this manual are for guidance only. They are
current and correct as of the date of publication but are subject to change
without notice.

1.1 How to Use this Guide
Use this configuration guide as the starting point for developing a StorageWorks
subsystem. This guide addresses the major considerations for designing a
StorageWorks subsystem. Consider the following factors when designing your
subsystem:
•

Host Computer System
The host computer system to include the operating system and revision level;
the SCSI (small computer system interface) controller or adapter used;
the SCSI bus speed (fast or slow); and the SCSI connector type (high- or
low-density, single-ended or differential, 50- or 68-pin). Each of these are
discussed in the detail required for planning and configuring a system. Refer
to the host or controller documentation for detailed information.

•

StorageWorks Subsystem Use
A subsystem used for expansion storage does not require as much planning as
as a RAID 5 (random array of independent disks level 5) subsystem.

•

Storage Devices
When selecting a storage device you must consider the media type, storage
capacity, reliability, and, when using multiple media types, the media must be
compatible with the SCSI controller.

•

FCC Operating Environment
All StorageWorks components can be used in a Class A environment. Some
of the components can be used in a Class B (home) environment. All the
components selected for a home environment must be certified as being FCC
Class B compliant.

1.3 StorageWorks Building Blocks
The StorageWorks building blocks (SBBs), shown in Figure 1–2, are the basic
building blocks of the StorageWorks subsystem. They are available for both 3½inch and 5¼-inch form factor devices. You can order SBBs with storage devices
installed or you can install third-party devices in a StorageWorks modular
carrier to create an SBB. SCSI bus converters, adapters, and power supplies can
also be mounted in SBBs.

1.4 StorageWorks Shelves
The StorageWorks shelves (refer to Figure 1–1) fit into any enclosure that can
accommodate a 445 millimeter (17.5 inch) device in either the horizontal or
vertical position. The mounting bracket kits permit installing a shelf in either a
data center cabinet with a metric mounting hole pattern or an HSC™ controller
cabinet with a Radio-Electronics-Television Manufacturer’s Association (RETMA)
mounting hole pattern. The shelf types include the following:
•

The basic SBB shelf, shown in Figure 1–3, contains SBBs and power
supplies.

All of these shelves require either an ac or dc input power supply mounted in an
SBB. The BA350–JA SBB shelf kit includes an ac power supply and the mounting
hardware. See the individual shelf user’s guide for a detailed description of a
particular shelf.

1.5 StorageWorks Controllers
The controllers (refer to Figure 1–1) are the interface between the host computer
and the SCSI–2 devices. These controllers are not interchangeable and can be
used only with a specific type host.
The function and purpose of the StorageWorks controllers are model specific. The
controllers are mounted in special shelves such as the one shown in Figure 1–4.

Introducing the StorageWorks Family 1–5

1.6 StorageWorks Enclosures
StorageWorks enclosures (SW500-series and SW800-series cabinets, and
BA350–Kx deskside expansion units) are used for mounting shelves. Desktop
expansion units (BA353–Ax) are used for mounting SBBs. Each enclosure
has a switch-controlled ac or dc power distribution unit. SW500-series and
SW800-series cabinet shelf mounting brackets are available in either the RETMA
or the metric mounting hole pattern.
The following enclosures can be used for StorageWorks products:
•

BA353–Ax series desktop expansion unit1 for mounting SBBs for use with
workstations and PCs as shown in Figure 1–5.

StorageWorks Storage Devices
This chapter contains descriptions of the StorageWorks storage devices. Check
with your Digital account representative for availability of additional devices.
Note
No attempt has been made to define StorageWorks compatible third-party
storage devices.
Devices that meet the basic criteria defined in Table 2–1 may be installed
in a modular carrier to create an SBB (StorageWorks building block).
Table 2–1 lists the general specifications for all StorageWorks devices.
Table 2–1 StorageWorks Devices—General Description
Criteria

Definition

Interface

The StorageWorks SCSI bus is SCSI–3 compliant. However,
the shelves only support single-ended SCSI–2 devices.

Device size (form factor)

3½-inch full-height or low-profile, fixed or removable media
devices.
5¼-inch half-height or full-height, fixed or removable media
devices.

Power

The total power requirements for the devices in one shelf
cannot exceed 131 watts. To make sure this requirement is
met, devices must spin up sequentially at 4-second intervals.

Heat dissipation

The SBB shelf blowers provide sufficient air flow to cool devices
mounted in an SBB.

SBB qualification

All Digital devices have been tested in an approved
StorageWorks configuration (that is, shelf, enclosure, power
supply, cabling, sequential device spin-up at 4-second intervals,
and so forth) and are in complete compliance with countryspecific standards (for example, FCC, TUV, CSA, and so forth)
and with Digital standards.
Customers are responsible for testing third-party devices for
compliance with country-specific standards.

FCC certification

All StorageWorks storage devices have been certified as being
FCC Class A compliant. Some devices have been certified as
being Class B compliant. FCC Class B installations require
that all components, specifically the shelf, power supply, and
storage devices, must all be Class B compliant. Use of a single
Class A component in a subsystem requires that the subsystem
be used only in a Class A environment. All SW500-series
departmental servers and SW800-series data center cabinets
can be used only in a Class A environment.

For information about a specific type device, see the following sections:
Cartridge tape drives—Section 2.7
CD–ROMs—Section 2.8
Disk drives—Section 2.5
Magazine tape subsystems—Section 2.10
Solid-state disks—Section 2.9
Optical disk drives—Section 2.6
Information is presented in a tabular form and is organized by form factor, either
3½-inch or 5¼-inch, with their basic specifications (for example, capacity, media,
transfer rate, rotational speed, and so forth). Detailed specifications are listed in
the Digital Systems and Options Catalog.

2.1 StorageWorks Building Blocks
The primary StorageWorks building block (SBB) is a SCSI–2 storage device
mounted in either a 3½-inch or 5¼-inch carrier. The first step in designing a
system is selecting storage devices with the following features:
•

Compatible media

•

Required storage capacity
Note
The SBB connectors are 96-pin female DIN connectors that provide
positive mating with the SBB shelf male connectors. The connector design
ensures that dc power is present until after the SCSI bus connection is
broken and that dc power is applied before the SCSI bus connection is
made. This feature protects the integrity of the SCSI data bus and avoids
introducing noise on the bus that could either distort data or cause the
bus to ‘‘hang.’’
The SBB connector is a simple, highly reliable mechanism that can
support 200 SBB replacement cycles. Removing and replacing an SBB
constitutes one replacement cycle. Over the projected StorageWorks
active product life of 5 years, this equates to 40 replacement cycles per
year, or approximately 1 cycle every 9 days. Excessive replacement cycles
wear away the gold contact coating and thus destroys the integrity of
the connection. The replacement cycle limit applies equally to shelf
connectors and device connectors.
Environments requiring a greater number of replacement cycles are not
supported and are considered as improper treatment or use (paragraph
9.4b of U.S. Standard Terms and Conditions). Products or connectors
damaged because of a higher number of replacement cycles are not
eligible for return under warranty and standard service plans.
Digital Equipment Corporation markets a distinct family of removable
storage elements for higher replacement cycle environments. Contact
your Digital Account Representative for more information.

2–2 StorageWorks Storage Devices

2.2 5¼-inch SBBs
The 5¼-inch SBB shown in Figure 2–1 can accommodate the following 5¼-inch
form factor devices:
•

Fixed media devices

•

Removable media devices

•

One full-height (82.6 mm [3.25 inch]) device

•

Two half-height (43.2 mm [1.7 inch]) devices

•

Three one-third height devices (_ _._ mm [_._ inch]) devices

Figure 2–1 Typical Full-Height 5¼-inch Storage Device SBB

CXO-4197A-PH

The following are the general rules for mounting half-height and one-third height
devices in one 5¼-inch carrier:
•

Different device types can be mounted in the same carrier, for example, a
tape drive and a CD–ROM.

•

The first device is normally mounted in the lower part of the carrier.1

•

The second device is normally mounted in the upper part of the carrier.
Unless specifically stated otherwise, the second device can be installed by the
user.

The InfoServer SWDCI–AA is an exception. It is always mounted in the upper part of
the carrier even when it is the only device in the carrier.

2.3 3½-inch SBBs
The 3½-inch SBB shown in Figure 2–2 can accommodate either a full-height (40.7
mm [1.6 inch]) or a low-profile (less than 25.4 mm [1-inch]) fixed or removable
media 3½-inch form factor storage device.
Figure 2–2 Typical 3½-inch Storage Device SBB

CXO-4196A-PH

2.4 SCSI Device Addresses
The SBB device addresses can be assigned either automatically by the SBB
shelf connectors or manually with the device address switches on the rear of the
SBB. See the StorageWorks Solutions Shelf and SBB User’s Guide for detailed
information on setting SBB device addresses.
Note
Not all 3½-inch SBBs have a device address switch. In these cases, the
device address is always assigned by the SBB shelf connector.

2.5 Disk Drives
Table 2–2 describes the Digital StorageWorks disk drives.
CAUTION
Do not operate 5¼-inch disk drives in the inverted position or the media
may be damaged.

StorageWorks Shelves
The following basic StorageWorks shelf types are described in this chapter:
•

The StorageWorks building block (SBB) shelf in which 3½-inch and 5¼-inch
form factor storage devices, controllers, and adapters are installed

•

The controller shelf in which controllers and the associated cache memory are
installed

•

The special purpose controller and SBB shelf in which controllers, the
associated cache memory, and 3½-inch and 5¼-inch form factor storage
devices, controllers, and adapters are installed1

The BA350–SB2 is the basic StorageWorks shelf. It can have a maximum of two
buses—a four-device bus and a three-device bus. A single, seven-device bus can
be created using the bus jumper board supplied with each SBB shelf. A dual-bus
storage devices SCSI terminator board is furnished with each SBB shelf. Each
SBB shelf can accommodate a maximum of eight 3½-inch SBBs as shown in
Figure 3–1. The 3½-inch SBB shelf power supply is always installed in Slot 7.
The shelf can have a combination of 3½-inch and 5¼-inch, SBBs as shown in
Figure 3–2. Remember, a 5¼-inch SBB occupies three shelf slots. Table 3–1 lists
some of the possible configurations.

3.2 Shelf Power Supplies
Each StorageWorks shelf requires an ac or dc input power supply. The power
supply type is determined by the internal enclosure power system, either ac or dc.
Any shelf can have a redundant power supply to preclude a single power supply
failure from disabling the shelf. In most cases, battery backup units (BBUs)
can be combined with the shelf power supply to provide extended system data
integrity. See Table 3–3 and the StorageWorks Solutions Shelf and SBB User’s
Guide for more information about the power supplies.
Table 3–3 contains the specifications for the BA35X–HA, the BA35X–HB, and the

StorageWorks Controllers, Converters, and Adapters

4–1

4.1 HSJ-Series Controllers
The HSJ controller series (the HSJ40 [6 SCSI ports] and HSJ30 [3 SCSI ports]
controllers), shown in Figure 4–1, connect a CI bus to a SCSI bus. These
controllers, their cache memories, and the power supplies are mounted in a
BA350–MA controller shelf. The SBBs are mounted in SBB shelves. Both the
controller and the SBB shelves can be installed in either an SW500-series or
SW800-series cabinet.1 There is no provision for installing these controllers in a
deskside expansion unit.
CAUTION
Installing CD–ROM devices and other storage devices on the same
HSJ-series controller SCSI bus can cause time-out problems. Do not
install any other storage device on a SCSI bus with a CD–ROM when
using an HSJ-series controller.

Figure 4–1 Typical HSJ-Series Controller Shelf Installation

CXO-3660A-PH

4.2 HSZ40-Series SCSI Controllers
The HSZ40 SCSI disk controller is a member of the Digital HSZ family of storage
array controllers and is installed in BA350–Mx series controller shelf. The HSZ40
controller connects a 16-bit wide, differential host computer SCSI port to six 8-bit,
single-ended SCSI device ports. A DWZZA SCSI signal converter is required.
The HSZ40 controller can be connected to a Digital host SCSI ports when the host
is running Digital OSF/1® software. Support for non-Digital hosts is provided for
the original equipment manufacturer (OEM) environment.

SW500-series and SW800-series cabinets can be only installed in an FCC Class A
environment regardless of the SBB shelf type.

4–2 StorageWorks Controllers, Converters, and Adapters

4.3 HSD05 DSSI Storage Array Controller
The HSD05 array controller, shown in Figure 4–2, connects a DSSI host to a
StorageWorks SCSI bus. This 3½-inch SBB connects to the DSSI bus with a
50-pin micro-ribbon cable attached to the connector on the front. Switches on the
back of the SBB define the DSSI node identification (node ID), the SCSI ID,
and the DSSI bus termination. The DSSI trilink connector and DSSI terminator
block provided with each HSD05 array controller are used to either position the
controller in the mid-bus position, or to permit its removal without interrupting
the bus.
The HSD05 has two connectors: a 68-pin high-density DSSI connector to which
the DSSI cable is attached, and a 96-pin DIN connector that connects to the SBB
shelf backplane connector. The single-ended terminators are mounted internally
and the converter can be used in either the end-bus or mid-bus position with an
HSD trilink connector.
Figure 4–2 HSD05 DSSI Storage Array Controller

CXO-4052A-PH_R

The HSD05 storage array controller is connected to the host with one of the DSSI
cables listed in Chapter 14. The 96-pin connector connects the controller to the
8-bit wide, single-ended SBB shelf SCSI bus.

4.4 HSD30 Array Controller
The HSD30 array controller can be configured either as a single controller, or
with another HSD30 in a dual-redundant configuration (failover support). The
HSD30 has three SCSI–2 device ports.
•

In the dual-redundant configuration, each port can support six devices.

•

In the single controller configuration, each port can support seven devices.

StorageWorks Controllers, Converters, and Adapters

4–3

4.5 SCSI Bus Signal Converters
The SBB shelf SCSI buses are 8-bit, single-ended, SCSI–2 buses. Some
controllers and hosts, or their SCSI adapters, use a 16-bit, differential SCSI
bus. Singled-ended and differential buses are incompatible and the SCSI protocol
will disable both buses when they are connected together.
As shown in Figure 4–3, SCSI bus signal converters permit connecting singleended and differential buses together without modifying the SCSI devices. For
an SBB shelf, the DWZZA-series SCSI bus signal converters are used perform the
following:
•

Establish compatibility between the host SCSI bus and the SBB bus

•

Extend the length of the SCSI bus

Two SCSI bus signal converters are used with StorageWorks products—the
DWZZA–Ax and the DWZZA–VA. Electrically and operationally, these models are
identical. The primary differences are as follow:
•

The DWZZA–Ax is a desktop model with a self-contained power supply
that can be connected to an SBB shelf or a DWZZA–VA converter. The
DWZZA–Ax has two female cable connectors—a 68-pin, high-density and a
50-pin, low-density.

•

The DWZZA–VA is always installed in slot 0 of an SBB shelf. It has a single
female cable connector—a 68-pin, high-density.
Note
The DWZZA–VA input connector is a 68-pin, differential connector. There
is no provision for connecting a 50-pin, single-ended connector to the
DWZZA–VA.

Both the DWZZA–Ax and DWZZA–VA models have internal differential SCSI
and single-ended SCSI terminators. These converters can be installed in either
the end-bus or the mid-bus position. The mid-bus position requires using the
H885–Ax trilink connector block.
The primary differences between the –Ax and the –VA convertors exist in
the enclosures (the –VA is mounted in a 3½-inch SBB; the –Ax is mounted
in a desktop enclosure) and the connectors. All of the cable connectors are
high-density (HD). Table 4–1 describes the major differences between these
converters.

4.6 HSZ1x-Series Disk Array Controllers
The HSZ1x-series SCSI disk array controller supports RAID levels 0, 1, 3, and
5. The controller is only used with RAID array subsystems and is mounted in
a controller and SBB shelf. This shelf has 5 SCSI buses, or channels, with one
3½-inch per bus (a one rank\ BOLD)2 bus) that can be expanded by adding SBB
shelves and 3½-inch SBBs up to a maximum of 30 SBBs (5 buses of 6 SBBs each,
a 5x6 configuration). All the StorageWorks RAID Array Subsystem shelves are
installed in deskside expansion units. The controller and SBB shelf is mounted
in two deskside expansion units, as shown in Figure 4–4.
The host SCSI channel is a synchronous/asynchronous, 10 MB/s (fast), 8-bit/16-bit
differential channel, and supports the SCSI–2 protocol. The host connector is a
68-pin, high-density, female connector. The second connector is a SCSI output
connector for connecting another controller or shelf in series.
There are five 8-bit, single-ended, synchronous/asynchronous, SCSI–2 channels
or interfaces. The controller provides active SCSI termination and terminator
power. For additional details, see the StorageWorks RAID Array 110 Subsystem
User’s Guide.

4.7 HSC Controller SCSI Channel Card
The HSC controller SCSI channel card HSS9X–Ax, shown in Figure 4–5
(commonly referred to as ‘‘K.scsi’’) expands the capabilities of the HSC-series
controllers3 to include SCSI devices. These controllers can operate with either
a single-ended host or a differential host operating in the 8-bit mode and can
be installed in either an HSC controller cabinet, such as the HSC95™ or in an
HSR95-series data center cabinet.
Figure 4–5 HSS9X–Ax ‘‘K.scsi’’ Controller Card

CXO-4202A-PH

Bus control is provided by the host adapter. The HSC-series controller uses
OpenVMS preferred pathing for dual pathing so two controllers can share the
SCSI bus and control a maximum of six SCSI devices. Only one adapter has
access at a time. In the event of a problem that does not involve the SCSI bus,
the other controller can assume control of the devices.

The InfoServer SW1000 controller SWDCI–AA, shown in Figure 4–6, is
an inexpensive means of connecting a remote network client system to a
StorageWorks SCSI bus. The SWDCI–AA is always installed in the upper half of
a 5¼-inch SBB. The client system is connected to the SBB front panel connector
with a thin-wire Ethernet cable. The SBB is always mounted in the the first
three SBB shelf slots (slots 0, 1, and 2). The InfoServer SW1000 connector mates
with the SBB shelf backplane connector in slot 0. The InfoServer SW1000 SBB
device address switch is set to 7, the host controller address, thereby overriding
the SBB backplane connector address.
A half-height storage device, such as a CD–ROM, can be mounted in the lower
portion of the SBB and its connector mates with SBB shelf backplane connector
in slot 2. This device also has a SCSI device address switch.

Alpha AXP System
StorageWorks Configurations
This chapter lists the basic data required for configuring Digital Alpha AXP
computer systems for operation with StorageWorks subsystems. A supported
system has been evaluated in the specified configuration (that is, the host
computer and SCSI adapter, and the StorageWorks controller, shelf, enclosure,
SCSI cable, and supported StorageWorks building blocks (SBBs) and complies
with country-specific standards (for example, FCC, TUV, and so forth) and Digital
standards.
Note
The information in this chapter is general in nature and is for guidance
only. See the Digital Systems and Options Catalog as well as Alpha
AXP system, controller, shelf, and enclosure publications for detailed
information about each element of the configuration. See Part III for
information about configuration rules and SCSI buses.

Column

Information
Host System

Models

Self-explanatory

SCSI Adapter—
Model and
Speed

The host SCSI adapter, or controller, used with the StorageWorks shelves and
the adapter’s bus speed , either fast (10 MB/s) or slow (5 MB/s). Some systems
have an embedded SCSI adapter in the host that can be used both for the internal
and the external SCSI–2 buses. In many cases, the external SCSI bus requires
another adapter, such as the KZMSA–AB, for the SBB SCSI bus.
The rate at which the adapter can transmit data over the SCSI–2 bus, either
fast (10 MB/s) or slow (5 MB/s), is independent of the other elements in the
configuration. However, the devices on the bus, such as an RZ25–VA, may not be
able to process data at a fast rate. The adapter identifies the maximum rate at
which individual devices can process data and uses this rate for that device.

Note
When the adapter can transmit at the fast rate and there is at least
one fast device on the bus, the SCSI bus must be designed as a fast bus
(maximum length 3.0 meters [9.8 feet]). This bus cannot function as a
slow bus.

StorageWorks—
SCSI Cable

The SCSI cable recommended for connecting the host system to the controller,
shelf, or enclosure. The cable length is a function of the physical configuration and
the bus speed. SCSI cables are described in detail in Chapter 12.

StorageWorks—
Component

The information in this column defines the following:
The shelves used for the controllers or the SBBs
The enclosures containing the shelves

StorageWorks—
Devices

The devices that are supported in a specific configuration. Other devices may be
compatible, but have not been evaluated in this configuration.

Note
Unless specifically stated otherwise, all buses are assumed to operate
as a single-ended, slow SCSI bus with a transfer rate of 5 MB/s and a
maximum cable length of 6.0 meters (19.7 feet).

StorageWorks Configurations
This chapter lists the basic data required for configuring Digital PC (personal
computer) systems for operation with StorageWorks subsystems. A supported
system has been evaluated in the specified configuration (that is, the host
computer and SCSI adapter, and the StorageWorks controller, shelf, enclosure,
SCSI cable, and supported StorageWorks building blocks (SBBs), and complies
with country-specific standards (for example, FCC, TUV, and so forth) and Digital
standards.
Note
The information in this chapter is general in nature and is for guidance
only. See the Digital Systems and Options Catalog as well as PC system,
controller, shelf, and enclosure publications for detailed information about
each element of the configuration. See Part III for detailed information
about configuration rules and SCSI buses.

General Configuration Rules
This chapter describes the general configuration rules for StorageWorks products.
These rules may appear multiple times in this chapter because some rules apply
to multiple products.
There are two types of configurations rules—logical and physical.
•

Logical rules describe items such as selecting a device address.

•

Physical rules define capacities, cable lengths, and so forth.

The following sections are organized by general subject and include both the
logical and physical configuration rules.
Note
Configuration rules for a specific StorageWorks product have precedence
over the general configuration rules listed in this chapter.

General Configuration Rules 11–1

11.1 Device Addresses
The following general configuration rules apply to StorageWorks device addresses:
•

Either the physical location of the storage device in the shelf or the device
address switch setting determines the SCSI device address (small computer
system interface) or ID of the following devices:
–

3½-inch devices 1

–

All 5¼-inch devices

The physical location device addresses are assigned from right to left as
viewed from the front, as shown in Figure 11–1.
Figure 11–1 Typical SBB Shelf—Device Addresses

(7)
POWER

SCSI
CONNECTORS

CXO-3617B-PH

•

The available device addresses for each shelf are 0 through 6.

•

The shelf slot numbers and the device addresses for 3½-inch SBBs
(StorageWorks building blocks) are the same.

•

The device addresses for most SBBs can be set either manually using the
address switch on the rear of the SBB or automatically by the shelf connector.
The default address is ‘‘automatic’’ to activate the shelf connector device
address. (For detailed information on setting device addresses with the
switches, see the StorageWorks Solutions Shelf and SBB User’s Guide.)

•

The shelf power slot is always slot 7 and does not have a device address.

Some 3½-inch disk drives do not have a device address switch.

11–2 General Configuration Rules

11.2 SBB Shelves
The following general configuration rules apply to SBB shelves:
•

Shelf capacity is measured by the number of 3½-inch SBBs in the shelf (refer
to Figure 11–1).

•

Each 3½-inch SBB occupies one slot in a shelf.

•

All shelf power supplies and battery backup units (BBUs) are mounted in
3½-inch modular carriers.

•

Shelf power requirements are based on a maximum of seven 3½-inch SBBs.

•

All devices in a shelf must spin up sequentially under software control at a
4-second or greater intervals.

•

A 5¼-inch SBB requires three slots for mounting, as shown in Figure 11–2.

Figure 11–2 Typical 5¼-Inch SBB Installation

CXO-3608A-PH

•

The 5¼-inch SBB can hold either one full-height (FH), two half-height (HH)
devices, or three one-third height devices.
–

A 5¼-inch SBB with an FH device has one connector mounted in the
center position.

–

A 5¼-inch SBB with two HH or one-third height devices has two
connectors. The connector in the center position is for the lower HH
device; the other connector is for the HH device.

–

A 5¼-inch SBB with three one-third devices has three connectors. The
connector in the center position is for the lower device; the connector on
the left rear is for the upper device, and the connector on the right rear is
for the middle device.

General Configuration Rules 11–3

11.3 SCSI Bus
The following general configuration rules apply to StorageWorks SCSI buses:
•

The maximum number of storage devices on a single SCSI–2 bus is seven.

•

The total length of an 8-bit, single-ended, SCSI bus is the distance between
the two bus terminators.

•

The total length of an 8-bit, single-ended, SCSI bus operating at 10 MB/s
cannot exceed 3.0 meters (9.8 feet).

•

The total length of an 8-bit, single-ended, SCSI bus operating at 5 MB/s
cannot exceed 6.0 meters (19.7 feet).

•

The rate at which data is transferred over an 8-bit, single-ended, SCSI
bus is primarily determined by the capabilities of the host SCSI adapter or
controller. A controller is rated as either fast or slow based on the maximum
rate at which it can transfer data. Prior to transferring the data, the
controller determines the maximum rate at which each device can accept
data. If this rate is lower than the controller’s maximum rate, the controller
uses the lower rate for the transfer.
This capability enables the reliable transfer of data to both slow and fast
devices on the same bus, provided the bus is designed as a fast bus with a
maximum bus length of 3.0 meters (9.8 feet).
Note
When the adapter can transmit at the fast rate and there is at least
one fast device on the bus, the SCSI bus must be designed as a fast bus
(maximum length 3.0 meters [9.8 feet]).

•

The total length of a fast-wide, 16-bit, differential SCSI bus cannot exceed 25
meters (82 feet).

•

Both a single-ended and a differential SCSI bus can be extended using SCSI
signal converters. A maximum of two SCSI signal converters, including one
installed in the shelf, such as a DWZZA–VA, can be used on any one bus.

•

A single, fast SCSI bus cannot be used for more than two shelves.

•

All SCSI buses require termination at both ends of the bus.

•

The single-ended SCSI buses are terminated on the last shelf on the bus.
Note
SCSI buses must be terminated at both ends for proper operation. SBBs
do not terminate a bus; a BA35X–MB terminator board must be installed
on the shelf backplane.

•

The rules for installing SCSI bus terminators and jumpers are shelf specific.

•

Multiple SCSI buses on a shelf can be connected together using a jumper
board (BA35X–MC). For example, two buses can be connected into one; three
buses can be connected into two, and so on.

11–4 General Configuration Rules

•

The target ID addresses for hosts and controllers are normally as follow:
–

First (single) host or controller: slot 7

–

Second (dual) host or controller: slot 6

For a detailed description of the StorageWorks shelf SCSI buses, including
lengths, see Chapter 12.

11.4 HSZ-Series Disk Array Controllers
The basic rules for configuring the HSZ10–AA and HSZ15–AA disk array
controllers (part of the StorageWorks Redundant Array of Independent Disks
[RAID] subsystem) are primarily concerned with the disk drives. These rules,
listed in Table 11–1, are dependent upon the RAID level (0, 1, 3, or 5). For
detailed configuration rules, see the DEC RAID Subsystem User’s Guide.
Table 11–1 StorageWorks Raid Array Subsystem 110 Configuration Rules

Mirrored pair drives cannot be on the same channel

An LU (logical unit) is a grouping of drives that has its own device SCSI ID and number.
For most purposes, a logical unit is equivalent to an array.

11.5 HSZ40 SCSI Disk Array Controller
You must observe the following rules when configuring an HSZ40 SCSI disk array
controller:
•

The HSZ40 supports only disk storage devices.

•

There is no provision for dual-redundant (two controller) HSZ40
configurations.

•

An HSZ40 SCSI controller supports the following host adapters:

General Configuration Rules 11–5

11.6 HSJ Array Controller Family
The hierarchical storage controller (HSC) CI configuration rules for supporting
from 1 to 31 host nodes also apply to the HSJ array controller family. See the
Software Product Descriptions (SPDs) and release notes for specific configuration
rules for the following host adapters:
If Your System Is a

The Controller Supported Is:

SBO-based system

CI780

BI-based system

CIBCA–B

CIXCD

CAUTION
Installing CD–ROM devices and other storage devices on the same
HSJ-series controller SCSI bus can cause time-out problems. Do not
install any other storage device on a SCSI bus with a CD–ROM when
using an HSJ-series controller.

There are two types of HSJ array controllers—the HSJ40-series and the
HSJ30-series. The HSJ40-series has six SCSI ports (buses) and the HSJ30-series
has three SCSI ports (buses). The basic difference between these two types of
controllers is the total number of devices supported. The HSJ40-series supports
twice as many devices as does the the HSJ30-series.
A single controller shelf, such as the BA350–MA, can contain two controllers and
cache memories. Therefore, there are two sets of configuration rules:
•

Rules that apply to only the single controller configuration—see
Section 11.6.1.

•

Rules that apply to both configurations—see Section 11.6.2.

See the HS Family of Array Controllers User’s Guide for detailed information
about the HS family of array controllers.

11.6.1 HSJ Single Controller
The following general rules apply only to the single-controller configuration:
•

Install the controller either in the top slot or the right-hand slot.

•

A single controller port can support a maximum of two 5¼-inch, full-height
(FH) SBBs in a single SBB shelf.

•

A single controller port can support a maximum of four 5¼-inch, FH SBBs in
two adjacent SBB shelves.

•

A single controller port can support a maximum of six devices, using a
combination of 3½-inch and 5¼-inch SBBs.

•

A single controller port can support a maximum of seven 3½-inch storage
devices.

11–6 General Configuration Rules

11.6.2 HSJ Single and Dual-Redundant Controllers
The following configuration rules apply to both the single- and dual-controller
configurations:
•

The minimum number of power supplies per controller shelf and SBB shelf is
one.

•

The preferred number of power supplies per controller shelf and SBB shelf is
two.

•

The maximum number of SBBs supported by a single HJSJ40 controller is 42
(that is, seven devices per SCSI channel).

•

The preferred number of devices supported by a single HSJ40 controller is 36
(that is, six devices per SCSI channel).

•

The maximum number of SBBs supported by a single HJSJ30 controller is 21
(that is, seven devices per SCSI channel).

•

The preferred number of devices supported by a single HSJ30 controller is 18
(that is, six devices per SCSI channel).

•

CD–ROMs must be on a dedicated bus. No other storage devices, such as
disks or tapes, can be on the same bus.

•

A maximum of two adjacent SBB shelves3 can be connected to a single
controller port.

•

Half-rack or full-depth devices, such as the TZ867 tape drives, must have a
dedicated controller port. No more than two devices can be connected to a
single port.

The second shelf is mounted directly below the first shelf with no space between them.

General Configuration Rules 11–7

11.7 HSC SCSI Controller
This section describes the general rules for configuring the HSC SCSI controller,
commonly referred to as a ‘‘K.scsi controller.’’ For detailed configuration rules, see
the HSC Controller User’s Guide.

11.7.1 HSC Controller SBB Shelf—Single SCSI Bus

•

The SCSI bus is a slow bus with a maximum bus length of 6.0 meters (19.7
feet).

•

Place the HSC controller in the end bus position for differential SCSI bus
operations with a maximum bus length of 25 meters (82 feet).

•

Install the DWZZA–VA SCSI signal converter in slot 0.

•

using a trilink connector block (H885–AA).

11.7.2 HSC Controller SBB Shelf—Dual SCSI Buses
The following configuration rules apply when using both SCSI–2 buses on a shelf:
•

Install the terminator board (BA35X–MB) in the backplane connector
adjacent to slot 5.

•

Install the jumper board (BA35X–MC) in the backplane connector adjacent to
slot 1 for safekeeping. This board has no function in this configuration and
installing it here does not affect the SCSI bus operations.

•

The SCSI bus is a slow bus with a maximum bus length of 6.0 meters (19.7
feet).

•

Place the HSC controller in the end bus position for differential SCSI bus
operations with a maximum bus length of 25 meters (82 feet).

•

Install the DWZZA–VA SCSI signal converter in slot 0 or slot 1.

when a SCSI ‘‘A’’ cable is connected to the upper (JA1) shelf connector.

•

Disable the slot 1, DWZZA–VA SCSI signal converter, single-ended terminator
when a SCSI ‘‘A’’ cable is connected to the lower (JB1) shelf connector.

•

Disable the DWZZA–VA SCSI signal converter, differential terminators when
using a trilink connector block (H885–AA).

•

Only the HSC controller connected to the upper SCSI connector (JA1) can
monitor the SHELF_OK signal.

11–8 General Configuration Rules

11.7.3 HSC Controller Multiple SBB Shelves
Multiple SBB shelves can be used with an HSC controller, and they can be
configured as either a single- or dual-bus shelf using the following rules:

StorageWorks SCSI Buses
This chapter describes the basic StorageWorks data bus.

12.1 StorageWorks Data Bus Description
The StorageWorks data bus is an 8-bit, single-ended, small computer system
interface (SCSI). This bus has eight device addresses (0 through 7) that identify
devices on the bus.
•

Device address 7 is normally reserved for the host computer address.

•

The remaining seven addresses (0 through 6) are used for the individual
storage device addresses.

StorageWorks shelves use a SCSI bus that can transfer data either at a slow
rate (5 MB/s [Megabytes per second]) or the fast rate (10 MB/s). The rate at
which data is transferred is affected by many things. However, the two primary
concerns are as follow:
•

The maximum rate at which the controller or initiator can transmit data

•

The maximum rate at which the target device can process data

The rate at which data is transferred over an 8-bit, single-ended, SCSI bus is
primarily determined by the capabilities of the host SCSI adapter or controller.
A controller is rated as either fast or slow based on the maximum rate at which
it can transfer data. Prior to transferring the data, the controller determines the
maximum rate at which each device can accept data. If this rate is lower than
the controller’s maximum rate, the controller uses the lower rate for the transfer.
This capability enables the reliable transfer of data to both slow and fast devices
on the same bus provided the bus is designed as a fast bus with a maximum bus
length of 3.0 meters (9.8 feet).
CAUTION
When the adapter can transmit at the fast rate and there is at least
one fast device on the bus, the SCSI bus must be designed as a fast bus
(maximum length 3.0 meters [9.8 feet]).

StorageWorks SCSI Buses

12–1

The maximum length of the fast and slow buses, including all cables and shelf
buses, is shown in Table 12–1. All bus lengths are rounded off to the nearest
tenth of a unit.

12.2 Terminating SCSI Buses
The shelf end of the SCSI bus is terminated with a terminator board mounted on
the shelf backplane. See the individual controller documentation for termination
options.
Note
All StorageWorks SBB shelf SCSI buses are terminated on the shelf
backplane. There is no SCSI bus termination on any SBB device.

12.3 Computing SCSI Bus Lengths
Operation of an 8-bit, single-ended, SCSI bus is affected by the total bus
length (that is, the total distance between the two bus terminators). Failure to
accurately determine the total SCSI bus length can cause signal degradation
to the point where the bus is non-operational. Practical experience, especially
when dealing with a fast SCSI bus (10 MB/s transfer rate), has shown that the
limitations stated in Section 12.1 are applicable for most bus operations.
Use the procedures in the following sections to determine the SCSI bus lengths
for either single or multiple SBB shelves.

12.3.1 Single StorageWorks Shelf SCSI Bus Lengths
As shown in Figure 12–1, the SCSI bus for a single shelf is composed of the
following segments:
•

Segment A—The distance from the controller terminator (T1) to the SCSI
bus connector (BC).

•

Segment B—The length of the SCSI cable from the controller shelf to the
SBB shelf (either 1 meter [3.3 feet] or 2 meters [6.5 feet]).

•

12.3.2 Multiple StorageWorks Shelves SCSI Bus Lengths
As shown in Figure 12–2, the SCSI bus for multiple SBB shelves on a single SCSI
bus is composed of the following segments:
•

Segment A—The distance from the controller terminator to the shelf
backplane connector (port) and from there to the SCSI bus connector

•

Segment B—The length of the BN21H-series cable from the controller shelf
to the SBB shelf (either 1 meter [3.3 feet] or 2 meters [6.5 feet])

•

Segment C—The distance from the first or second SBB shelf input connector
through the jumper (J) to the shelf output connector

•

Segment D—The length of the SCSI cable (0.5 meters or 1.6 feet) that
connects the SBB shelves

•

Segment E—The distance from the last shelf input connector to the bus
terminator on the same shelf.

StorageWorks SCSI Cables
The process for selecting SCSI cables is basically the same whether or not the
host system is a Digital system. Part II lists the Digital systems StorageWorks
configurations to include the compatible SCSI cables. All you have to do is
determine the cable length.
For a non-Digital system, you must refer to the host system and controller
documentation and determine the following:
•

The SCSI adapter or controller type

•

The SCSI connector pin configuration (50-pin or 68-pin)

•

The connector configuration (straight, right-angle) and latching mechanism
(thumb latches, thumb screws, bale locks, and so forth)

•

The controller bus speed (fast [10 MB/s] or slow [5 MB/s]).

For all host systems you must then calculate the maximum SCSI bus cable
length. This is the difference between the maximum SCSI bus length, which is
determined by the bus speed, and the total of the following:
•

The SCSI bus length between the controller terminator and the controller
cable connector

•

The SCSI bus length between the shelf input connector and either the shelf
terminator or shelf output connector

•

The special cables

•

The cables connecting the SBB shelves

It is recommended that you select the shortest cable possible to connect the host
to the StorageWorks subsystem.

StorageWorks SCSI Cables

13–1

13.1 SCSI Cable Connectors
All BA350–SB SBB shelves have two SCSI, 50-pin, high-density, female
connectors. Only cables, such as the BN21H-series, with a SCSI 50-pin,
high-density, male, straight connector can be attached to the SBB shelves. The
BN-series StorageWorks SCSI cables are built to SCSI–3 specifications and
operate reliably as part of either a fast or slow bus.
Controllers can have both 50-pin, high-density, female connectors and 68-pin,
high density, female connectors. Only connectors with a 50-pin, high-density,
male, straight connector or a 68-pin, high-density, right-angle connector can be
attached to the StorageWorks controller shelves. The following sections contain a
general description of the StorageWorks-compatible SCSI cables for use with the
following components:
•

Shelves

•

Controllers

•

Host computers or adapters

All of the StorageWorks BN-series SCSI cables conform to SCSI–3 standards.

13.2 StorageWorks Shelf SCSI Cables
All the StorageWorks shelves and expansion units, such as the BA350–KB
deskside expansion unit and the BA353–Ax desktop expansion unit, have
SCSI ‘‘A’’ type 50-pin, high-density, female, straight connectors. Only cables
with a 50-pin, high-density, male, straight connectors, such as found on the
BN21H-series cables, can be used.
The following sections contain detailed descriptions of the compatible SCSI
cables, to include connectors, typical use, and lengths:
•

SCSI–2, 50-conductor, single-ended ‘‘A’’ cables—Section 13.4

•

SCSI–3, 68-conductor, differential ‘‘P’’ cables—Section 13.5

•

SCSI–2 and SCSI–3 special purpose cables, such as ‘‘Y’’ cables, trilink
connectors, and terminator blocks—Section 13.6

13.3 Recommendations for StorageWorks Shelves
Digital strongly recommends that the same length cables be used to connect all
the SBB shelves to the controller shelves in a cabinet or deskside expansion unit.
The following advantages can be realized:
•

The cables between shelves will not be under any strain.

•

All the SCSI–2 buses are the same length.

•

The possibility of unbalancing a bus by inadvertently exceeding the maximum
bus length is avoided.

13–2 StorageWorks SCSI Cables

13.4 SCSI ‘‘A’’ Cables
The SBB shelf SCSI bus is an 8-bit wide, single-ended bus with two 50-pin,
high-density, female connectors (JA1 and JB1). The compatible cable for these
connectors is a 50-conductor cable with a 50-pin, high-density, shielded male,
straight connector with thumb latches (also known as squeeze-to-release latches).
This combination of conductors and connectors is a SCSI ‘‘A’’ cable.
The primary difference between the ‘‘A’’ cables is the connectors. The following
sections describe the different types of SCSI ‘‘A’’ cables that are compatible with
the SBB shelves. Table 13–1 lists the SCSI ‘‘A’’ cable specifications, to include
connectors, length, and cable order numbers.

13.6 Special SCSI Cables
There are many compatible SCSI devices that cannot be connected together using
the standard SCSI ‘‘A’’ or ‘‘P’’ cables. In some special cases there is a requirement
to connect a SCSI adapter to multiple controllers, place a device in the middle of
the bus, or other special configurations. Most of these cases can be handled using
a trilink connector block (a ‘‘Y’’ connector) or a ‘‘Y’’ cable.
Table 13–3 lists the StorageWorks-compatible adapter SCSI cables by function
(listed alphabetically).
Note
The length of all ‘‘–0B’’ ‘‘Y’’ adapter cables is 0.15 meters (6 inches).

13–8 StorageWorks SCSI Cables

Table 13–3 Selecting a ‘‘Y’’ SCSI Cable
To do this

Use this cable

Connect a 16-bit bus (operating in the 8-bit mode) ‘‘P’’ cable to a
50-pin low-density connector.

See Figure 13–14.

Use with Sun Microsystems® or Hewlett-Packard® systems.

Connect a high-availability OSF™ configuration host cables, such

You must also use a 68-pin, differential, terminator block
(H879–AA).

As shown in Figure 13–10, you can adapt a 68-pin ‘‘P’’ cable to a 50-pin ‘‘A’’
connector simply by connecting a ‘‘Y’’ cable, 68-pin, female connector to the male
cable connector. By installing the differential terminator block in the other 68-pin
‘‘Y’’ cable connector, you now could disconnect the ‘‘Y’’ cable to the adapter without
interrupting the SCSI bus because the differential terminal block in the ‘‘Y’’ cable
now terminates the bus.

StorageWorks DSSI Cables
The process for selecting DSSI (DIGITAL standard system interface) cables is
basically the same whether or not the host system is a Digital system. You
must refer to the host system and controller documentation and determine the
following:
•

The DSSI adapter or controller type

•

The connector configuration (straight or right-angle)

For all host systems you must then calculate the maximum DSSI bus cable
length. This is the difference between the maximum DSSI bus length and the
total of the following:
•

The DSSI bus length between the host controller terminator and the host
controller cable connector

•

The DSSI bus length between the HSD-series controller cable connector and
the HSD-series controller DSSI terminator

Digital recommends that you select the shortest cable possible to connect the host
to the StorageWorks subsystem.
The HSD05 storage array controller SBB is connected to the host with one of
the DSSI cables listed in Table 14–1. The SBB 96-pin connector connects the
controller to the 8-bit wide, single-ended SBB shelf DSSI bus.

Designing a StorageWorks Subsystem
Designing a StorageWorks subsystem is a complex process that requires you to
consider many factors. This chapter contains examples of the steps involved in
configuring some of the more basic subsystems. To reduce the complexity of the
process, the examples are limited to subsystems that use the following:
•

HSZ10–AA disk array controller

•

BA350–Ex controller and SBB (StorageWorks building block) shelf

•

BA350–Sx SBB shelf

•

BA350–Kx deskside expansion unit with an ac distribution unit

•

120 Vac 60 Hz input power

15.1 Before You Begin
Before designing a StorageWorks subsystem, you should do the following:
1. Determine the storage requirements, to include the media, the storage
capacity, and so forth.
2. Determine the bus type and the device that will control the bus.
3. Select the SBBs, controllers, shelves, and enclosures listed in Part I that meet
your requirements.
4. Familiarize yourself with the configuration rules in Chapter 11 for the
preferred configuration.
5. Determine which SCSI (small computer system interface) cables, listed in
Chapter 12, are compatible with the preferred configuration, taking into
account the shelf bus length, bus speed (fast or slow), and cable length.
6. Study the configuration examples presented in the following sections.

Assumptions: The following assumptions have been made about this
configuration:
•

The user wants one HSZ10–AA disk array controller.

•

The HSZ10–AA disk array controller is operated from a KZESA adapter.

•

The user wants a battery backup unit (BBU) to maximize data integrity.

•

The user needs 4 GB of storage in a RAID 5 (Redundant Array of Independent
Disks, level 5) configuration.

•

The user wants the SBB shelf in deskside expansion enclosures.

•

The configuration will be used in France.

Storage Capacity: This configuration uses five disk drives. Four RZ26–VA disk
drives are used to meet the user’s storage requirements, providing 4.20 GB of
storage. Because RAID 5 configurations require n+1 disks, an additional (fifth)
disk drive is used to meet RAID requirements.
Enclosure: Two BA350–Kx deskside expansion enclosures.

15–2 Designing a StorageWorks Subsystem

SCSI Connections: In this example, two levels of SCSI connections must be
considered:
•

The first is the SCSI connection from the KZESA adapter to the HSZ10–AA
disk array controller.

•

The second is the SCSI connection from the controller and SBB shelf to the
SBBs.

The SCSI connection from the KZESA adapter to the HSZ10–AA disk array
controller is accomplished with a BN21K cable and a ‘‘Y’’ cable (described in
Chapter 12). A 68-pin terminator is also needed for this arrangement.
The controller and SBB shelf can accommodate up to six SCSI buses. Each
disk drive has its own separate SCSI bus from the HSZ10–AA controller. This
connection is made on the backplane.
Power Cord: A BN19W–2E power cord is used.
Parts Lists: The parts list for the controller and SBB configuration in this
example is as follows:
•

One BA350–Ex controller and SBB shelf

•

Two BA350–Kx deskside expansion enclosures

•

One HSZ10–AA disk array controller

•

Five RZ26–VA disk drives

•

Two BA350–HA ac input power supplies

•

One BA350–HC BBU

•

One BN21K–03 SCSI cable

•

One BN21P–0B ‘‘Y’’ cable

•

One H879–AA 68-pin terminator

•

One BN19W–2E Central Europe 220 V ac power cord (France)

Assumptions: The following assumptions have been made about the
configuration in this example:
•

The user wants one HSZ10–AA disk array controller.

•

The HSZ10–AA disk array controller is connected to a KZESA adapter.

•

The user wants a BBU for the RAID controller and redundant power for the
disks.

•

The user needs 9 GB of storage.

•

The user wants the SBB shelf in deskside expansion enclosures.

•

The system will be used in France.

Storage Capacity: The configuration in this example has a total of 10 RZ26–VA
disk drives, 5 in each shelf. These disks provide a total storage capacity of 10.5
GB: 9.45 GB to satisfy the user’s storage requirements, plus an additional disk to
satisfy the RAID 5 requirement of n+1 disks.
Enclosure: Three BA350–Kx deskside expansion enclosures.

15–4 Designing a StorageWorks Subsystem

SCSI Connections: In this example, two levels of SCSI connections must be
considered:
•

The first is the SCSI connection from the KZESA adapter to the HSZ10–AA
disk array controller.

•

The second is the SCSI connection from the controller and SBB shelf to the
SBB shelf.

The SBBs in the controller and SBB shelf are connected to the SCSI buses
internally, on the shelf backplane.

•

The SBB shelf is connected to the controller and SBB shelf with a BN21H–02
SCSI cable.

Power Cord: A BN19W–2E power cord is used. Only two power cords are
needed since the controller and SBB shelf can be powered from one ac distribution
unit.
Parts Lists: The parts list for this combination subsystem is as follows:
•

One BA350–Ex controller and SBB shelf

•

One BA350–Sx SBB shelf

•

Three BA350–Kx deskside expansion enclosures

•

One HSZ10–AA disk array controller

•
