Chapter 1. Introduction
This chapter describes the operating specifications, features, and components for
the IBM System Storage DS5100 and DS5300 (Machine Type 1818) Storage
Subsystem (hereafter referred to as
DS5100 and DS5300 or storage subsystem ).
This chapter also includes an inventory checklist and important information on best
practices guidelines and product updates for your DS5100 and DS5300.
Overview
The DS5100 and DS5300 supports the large and growing data storage
requirements of business-critical applications. The storage subsystem offers you
data access and protection to meet your existing enterprise storage requirements
and prepare for the future.
The DS5100 and DS5300 is designed to provide solutions to meet the needs of
midrange/departmental storage requirements, delivering high performance,
advanced function, high availability, modular and scalable storage capacity, with
SAN-attached 4-Gbps fibre channel (FC) connectivity, and support for RAID levels
0, 1, 3, 5, and 6.
The DS5100 and DS5300 supports attachment of EXP5000 and EXP5060 storage
expansion enclosures. The DS5100 and DS5300 supports configurations of FC or
Serial Advanced Technology Attachment (SATA) disks, or a mix of both types of disk
drives. For details on the maximum number of disk drives supported, maximum
storage capacity, and other features of the storage subsystem, see “Features at a
glance” on page 2.
The DS5100 and DS5300 has two slots per controller for Host Interface Cards
(HICs). The supported HICs are four-port 4 Gbps Fibre Channel (FC), four-port 8
Gbps Fibre Channel (FC), and two-port 1 Gbps iSCSI. Any combination of HICs is
supported; however, each controller must have the same type HICs in identical slot
positions.
Advanced DS4000, DS5100, and DS5300 storage management, copy service
options, and optional advanced disaster recovery functions are available for the
DS5100 and DS5300, including FlashCopy
®
, VolumeCopy, and Enhanced Remote
Mirroring.
The DS Storage Manager client is also available for the DS5100 and DS5300. This
storage management software is designed to help centralize storage management,
help simplify partitioning of the DS5100 and DS5300 series storage into as many as
512 virtual servers, and strategically allocate storage capacity to maximize storage
space.
Models
The DS5100 and DS5300 Storage Subsystem includes these models:
v DS5100 (Model type 51A)
v
DS5300 (Model type 53A)
Both models are primarily the same; however, cache memory size and internal
processor bus speed differ. See Table 6 on page 17 for details. For additional
