Enterprise Storage Array for I/O Intensive Applications

This document is a user's guide for the Digital Equipment Corporation StorageWorks Enterprise Storage Array (ESA), designed for I/O intensive applications. It provides detailed concepts and procedures for the installation, configuration, and use of the ESA across multiple operating systems. The guide describes the major components of the ESA, which include the cabinet, StorageWorks Building Block (SBB) shelves for disk drives, power supplies, and external cache batteries (ECBs), Cable Distribution Units (CDUs), array controllers with their operating software (HSOF), and fan trays. It also covers the operation and fault notification for SBB devices and controllers, redundant power configurations, and cabling interconnections. A substantial part of the manual is dedicated to preparing various host systems—including Digital UNIX, HP-UX, IBM AIX, Solaris, Windows NT (Alpha and Intel)—to operate with the ESA, detailing host adapter installation, device driver setup, kernel configuration, and logical unit number requirements. Finally, the document introduces the StorageWorks Command Console (SWCC), a graphical user interface and network management program for monitoring, configuring, and troubleshooting the ESA, outlining its features, program modules, supported RAID configurations (RAID 0, 1, 0+1, 3/5), and installation process.
