RZ28L, RZ29L, and RZ40

This document provides product notes for the Digital StorageWorks RZ28L, RZ29L, and RZ40 Fast Narrow Disk Drive Building Blocks (SBBs), detailing their specifications and application notes.

These are SCSI single-ended disk drives compatible with a wide array of operating systems and platforms, including Alpha Windows NT, DIGITAL UNIX, OpenVMS, Intel Windows (NT), Novell, HP9000 (700/800), IBM RS/6000, and Sun SPARC systems.

Key features include:

• Performance: Magneto Resistive (MR) heads, 7200 rpm spindle speed, 8 ms average seek time.
• Data Transfer: Asynchronous and Synchronous data transfer protocols.
• Management: Programmable sector size reallocation, tagged command queuing with multi-initiator support, staggered disk spin-up (to prevent power supply overloads).
• Reliability: Self-diagnostics, 5-year warranty, and compliance with UL, CSA, and VDE standards.

The models offer formatted capacities of 2.10 GB (RZ28L), 4.29 GB (RZ29L), and 9.10 GB (RZ40). The document includes detailed tables for physical dimensions, environmental conditions, power requirements, logical configuration, and disk geometry data for all models.

Application notes provide operating system-specific guidance:

• Alpha/Intel Windows NT, MS-DOS, Netware: No special OS-specific instructions are needed.
• DIGITAL UNIX and OpenVMS: The RZ40 model requires specific OS versions (3.2D/4.0 for UNIX, 6.0/6.2 for OpenVMS) for support.
• HP-UX V10.x: Instructions are provided for optimizing filesystem size using disktab and newfs.
• IBM AIX RS/6000: Details cover drive installation and volume group management via SMIT or command-line utilities.
• Solaris: Guidance is given for configuring disk label information using /etc/format.dat and the format utility.
