29 Chapter 1. Introduction This chapter proides the following information: An oeriew of the IBM TotalStorage Enterprise Storage Serer (ESS) Descriptions of data integrity features and performance features A description of how the ESS is configured as logical subsystems Oeriew of the IBM TotalStorage Enterprise Storage Serer The IBM TotalStorage Enterprise Storage Serer (ESS) is a member of the Seascape family of storage serers. The ESS concurrently supports dierse host systems oer dierse attachment protocols. You can allocate data storage among the attached host systems with the ESS Specialist, a Web-based interface. The ESS proides integrated caching and support for the attached disk drie modules (DDMs). The DDMs are attached through a serial storage architecture (SSA) interface. Disk storage on an ESS is aailable in modules that contain eight DDMs. IBM calls these modules disk eight packs. The ESS proides the following major features. See ESS data integrity, aailability, and performance features on page 21 for more details. Support of an intermix of types of RAID (redundant array of independent disks) Support of non-raid disk groups Note: ESS Models 800 and 750 do not support non-raid disk groups. Fast reduced instruction-set computer (RISC) processors A fault-tolerant system Fast disk dries with speeds of and reolutions per minute (rpm) Disk capacity that you can assign and reassign among attached host systems Instant copy solutions with FlashCopy Disaster recoery solutions with Peer-to-Peer Remote Copy (PPRC) The ESS models support the following features: Model 750 Supports a two-way processor. Supports 8 GB of cache. Support for 72.8 GB and GB RPM dries that can be intermixed and configured as RAID 5, 10, or a both. Supports up to eight disk eight-packs and up to TB of physical capacity. Model 800: Supports either a standard processor or an optional turbo processor. Supports 8 GB of cache and an optional 16, 24, 32, or 64 GB of cache. Models F10 and F20: Support a standard processor. Note: Models F10 and F20 are no longer aailable from the factory. Model 800 supersedes Model F20. This publication includes information about Models F10 and F20 for those models that are currently in the field. IBM will continue to support these models. Copyright IBM Corp. 1999,
