Intended Audience
The guide is intended for all Digital Customer Service engineers installing SF7x-HA/-JA and SF3x-BA/HA/JA DSSI disk storage enclosures
as embedded storage into a VAX 6000 Series Processor Cabinet. Reading
this manual is necessary for proper installation.

Chapter 1
Safety Precautions
1.1 Introduction
This chapter discusses hazards and safety precautions. The Digital
Services engineer should be aware of these hazards and precautions
when installing SF7x/SF3x disk storage enclosure options as embedded
storage in a VAX 6000 Series Processor cabinet.
WARNING
Only qualified Digital Services engineers can perform installation and maintenance of any equipment described or referred
to in this manual.
Digital customer access to VAX 6000 embedded storage options is limited to SF7x/SF3x enclosure operator control panels (OCPs) through openings in the system cabinet front door.
Digital customer access to embedded storage options by opening
system cabinet front or rear doors is prohibited.

1.2 Hazards and Safety Precautions
The front and rear doors of a VAX 6000 series processor cabinet are
considered safety barriers. High voltages and the blower assembly are
accessible once the front door is opened and high voltages are accessible
once the rear door is opened.

Safety Precautions 1–1

Both cabinet doors are locked and cannot be opened without a 5/32 hex
key. Only Digital Services engineers can open the front or rear door
without violating Digital safety measures.

1.3 ESD Precautions
Only Digital Service engineers with training in electrostatic discharge
(ESD) procedures should install VAX 6000/SF7x/SF3x embedded storage
options and hardware or work with the processor cabinet.
Digital Services engineers must wear proper ESD protective ground
straps connected to a good ground when accessing, installing, or repairing embedded storage options or VAX 6000 series processor cabinets.
ESD kits, containing protective ground straps, are behind the front
and rear doors of the processor cabinet. Use these ground straps
when performing services on the processor cabinet. When installing or
servicing an option, use a separate ground strap, connected directly to
the option.

1.4 System Grounding Precautions
Proper grounding is required between the VAX 6000 system and any
enclosures connected via a common DSSI bus.
WARNING
If the enclosures are not connected to a common ground, a
personal safety hazard could result.

If the ground offset voltages generated in the power distribution system
exceed allowable limits, data transmission across the DSSI bus can be
affected. System(s) performance could be degraded significantly and data
could be corrupted.

1–2 Safety Precautions

For a DSSI installation, the maximum ground offset voltage differential
allowed between enclosures is:
DSSI Bus Length1

Allowable Offset

Meters

Feet

Up to 20

Up to 65

200 mv

70 mv (rms)

20-25

65-82

40 mv

14 mv (rms)

1 The total length includes all DSSI cable lengths, internal and external to the enclosures.

Ensure that the power distribution systems meet local codes prior to
DSSI system installation. In a properly wired power distribution system(s) connected to properly functioning (no ground faults) equipment,
generally no further attention to grounding is needed. The power distribution system provides a satisfactory path between enclosures.
To ensure proper grounding, perform a power system survey before
installation by answering the following questions:
1. Do any outlets being used not have power ground connections?
2. Is the grounding prong missing on any of the computer equipment
power cords?
3. Are any of the power outlet neutral connections actually ground
connections?
4. Are the grounds for any of the power distribution cirtuits (outlets)
not connected to the same power distribution panel?
5. Are any devices not UL or IEC approved connected to the same
breaker as any of the DSSI computer equipment?
If the answers to all of the above questions are "no", then the grounding
should be adequate for DSSI operation.
It is recommended that the ground offset voltage between any two enclosures be measured. However, this only provides data for that particular
moment in time. Ground offset values may change as additional devices
are connected to the same power source.

Safety Precautions 1–3

If the installation shows ground offset voltages between interconnected
enclosures exceeding the allowable limits, use one of the following solutions:
a. Have an electrician correct any deficiencies detected during the
power system survey. This solution is recommended.
b. Install grounding cables between enclosures. Grounding cables,
available from Digital, come with the necessary hardware for installation.
Installation of additional grounding cables normally reduces the
ground voltage offset sufficiently to meet the requirements. In severe
cases, however, the cables may not be large enough. This is revealed
by the ground offset voltage measurements.
If the additional grounding cables are not adequate, trace the source
of the ground offset voltage, which should be reduced or eliminated.

procedure is necessary.

2.3 Storage Enclosure Overview
The SF-series storage enclosures are available as follows::
•

SF3x enclosure, which contains up to twelve half-height, 3-1/2" ISEs

•

SF7x enclosure, which contains up to four full-height, 5-1/4" ISEs.

Each disk ISE within an SF-series enclosure is independently controlled
from the operator control panel (OCP) on the front of the enclosure. A
power supply in the enclosure provides the DC power and cooling for all
disk ISEs installed in the enclosure.

2.3.1 SF3x Storage Enclosure
The SF3x storage enclosure (Figure 2–3) holds up to twelve RF3x series
ISEs. Six slots are in the front of the enclosure and six slots are in the
rear. Disk ISEs installed in these slots plug directly into a backplane,
which is cabled to a connector tray on the top rear of the storage
enclosure.
The SF3x enclosure can be configured in:
•

Through-bus mode

•

Split-bus mode

In through-bus mode, the six ISEs in the front of the SF3x enclosure are
connected to a single DSSI bus, and the six ISEs on the rear of the SF3x
enclosure are connected to a second DSSI bus.
In split-bus mode, each end of the enclosure (front and rear) is further
divided into left-side ISEs and right-side ISEs, each connected to a
separate DSSI bus. Thus, in split-bus mode there are four DSSI buses,
each with three drives connected to it.

VAX 6000/SF7x/SF3x Embedded Storage Options 2–9

2.3.2 SF7x Storage Enclosure
The SF7x series storage enclosure (Figure 2–4) holds either two or four
RF7x series ISEs. The ISEs in the SF7x storage enclosure can also be
configured in:
•

Through-bus mode

•

Split-bus mode

In through-bus mode, all four disk ISEs are connected to a single DSSI
bus.
In split-bus mode, the left-side ISEs are connected to one DSSI bus, while
the right-side ISEs are connected to a second DSSI bus.
Both SF-series storage enclosures have the following features:
•

Operate in one of two modes: through-bus or split-bus.

•

Each disk ISE has its own set of switches and indicators on the OCP.

•

The enclosure power supply provides operating power to all disk ISEs
and other subassemblies in the enclosure.

•

The drive DC power switches for the disk ISEs are on the front panel
of the storage enclosure.

Specifications for the SF3x series storage enclosure are shown in Table 2–4. Specifications for the SF7x series storage enclosure are shown
in Table 2–5.

4.8.2 SF3x DSSI Node Numbers
The SF3x embedded storage enclosure DSSI node numbers are preset at
the factory as nodes 0-5. Table 4–2 lists the DSSI node IDs set at the
factory:
Table 4–2: SF3x Factory-set DSSI Node IDs
Position

Backplane Location

DSSI Node ID

upper left slot

upper right slot

middle left slot

middle right slot

lower left slot

lower right slot

In some installations, SF3x DSSI node numbers may have to be changed
to accommodate other devices configured on the same DSSI bus.
To determine if it is necessary to change the node numbers, consider:
1. The number of RF3x ISEs installed in the SF3x enclosure
•

If this is a (2) drive option (SF3x-BA), only node 0 and 5 will be
used leaving nodes 1-4 for other devices.

•

If this is a (6) drive option (SF3x-HA), nodes 0-5 inclusive will be
used. The rear half (DSSI bus 1) of the SF3x Option will be fully
populated.

•

If this is a (12) drive option (SF3x-JA), nodes 0-5 inclusive will
be used on both DSSI buses (front and rear of the SF3x enclosure
are fully populated).

2. KFMSA DSSI node numbers
•

DSSI node numbers assigned to the KFMSA XMI Adapter Module(s) should not conflict with the DSSI node numbers of the ISEs
within the SF3x enclosure.

•

Installing the SF3x Embedded Storage Option in a DSSI VAXCluster environment may produce conflicting DSSI node numbers.
Installing the SF7x/SF3x Embedded Storage Options 4–29

3. TF85B-AA Embedded Tape Drive Node number
•

The TF85B-AA embedded tape drive subsystem is preset at the
factory as DSSI node number 0. If you are connecting the SF3x
option to the same DSSI bus as that of the TF85B-AA, ensure
each DSSI node number is unique.

If it is necessary to change the SF3x DSSI node numbers, follow Section 4.8.2.1.
4.8.2.1 Changing the SF3x Node Numbers
You can change the DSSI node ID for an ISE in any given slot position by
using DIP switches provided on the SF3x enclosure’s transition module.
Figure 4–13 shows the location of the switches for each slot position.
Table 4–3 shows what the switches must be set to for each slot position.
To set the SF3x DSSI node numbers, use the following tables. Refer to
Figure 4–13 for switch pack location of each RF3x ISE within the SF3x
storage enclosure.
NOTE
In SF3x enclosure options not fully populated (-BA and -HA
variations), empty RF3x ISE slots do not occupy a DSSI node
on that specific bus. To prepare for upgrades to these SF3x
enclosures, switch settings may be set at initial installation.

Appendix A
Split–Bus/Disk Striping VAX 6000/SF7x/SF3x
Embedded Storage Systems
A.1 Disk Striping Overview
The software, VAX Disk Striping Driver, implements disk striping for
the VMS Operating System. Disk Striping interleaves multiple disks
to improve I/O performance in the same way high-performance memory
systems interleave memory banks.
In each case, data requests are decomposed and distributed to storage
components processing those requests in parallel.
Disk Striping is a layered product that can relieve three types of I/O
performance problems:
•

Applications requiring very high data transfer rates

•

Systems in which static disk load balancing is ineffective

•

Applications prohibited from distributing data across multiple disks,
but need higher throughput than is available from a single disk

The VAX Disk Striping Driver software is furnished under the licensing provisions of Digital Equipment Corporation’s Standard Terms and
Conditions. For more information, refer to Software Product Description, SPD 31.66.01, (AE-NZ29B-TE) and SSA 31.66.01-A, (AE-NZ30BTE), April 1991.
