RZ1BB, RZ1CB, and RZ1DB

This document provides product notes for the Digital Equipment Corporation RZ1BB, RZ1CB, and RZ1DB Ultra Wide Disk Drive StorageWorks Building Blocks (SBBs).

These SBBs are designed for compatibility with SCSI single-ended interfaces and are supported across a wide range of operating systems, including Alpha Windows NT, DIGITAL UNIX, Intel-compatible Windows/NT/Novell, HP9000, IBM RS/6000, SGI IRIX, and Sun SPARC platforms.

Key specifications highlight their performance and features: they are Ultra Wide SCSI drives utilizing Magneto Resistive (MR) heads, operating at 7200 rpm with an 8 ms average seek time. They support both asynchronous and synchronous data transfer protocols, programmable sector size reallocation, tagged command queuing, and multi-initiator support. A notable feature is staggered disk spin-up, designed to prevent power supply overloads by sequentially powering up drives based on SCSI ID. The drives offer capacities of 2.10 GB (RZ1BB), 4.29 GB (RZ1CB), and 9.1 GB (RZ1DB), come with a 5-year warranty, and comply with UL, CSA, and VDE standards.

The document also includes extensive application notes, detailing specific operating system requirements and configuration procedures for integrating these drives into various environments, such as DIGITAL Unix, OpenVMS, HP-UX, IBM AIX RS/6000, SGI IRIX, and Solaris.
