7 days a week. In the U.K., these services are available Monday through Friday,
from 9 a.m. to 6 p.m.
Fire suppression systems
A fire suppression system is the responsibility of the customer. The customer’s own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should be consulted in selecting a fire suppression system that provides the correct
level of coverage and protection. IBM designs and manufactures equipment to
internal and external standards that require certain environments for reliable
operation. Because IBM does not test any equipment for compatibility with fire
suppression systems, IBM does not make compatibility claims of any kind nor does
IBM provide recommendations on fire suppression systems.

xxvi IBM TotalStorage DS4500 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide
Chapter 1. Introduction
This chapter describes the operating specifications, features, and components for
the IBM TotalStorage DS4500 Storage Subsystem (hereafter referred to as DS4500
or storage subsystem).
This chapter also includes an inventory checklist and important information on best
practices guidelines and product updates for your DS4500.
Overview
IBM DS4000 solutions support the large and growing data storage requirements of
business-critical applications. These scalable IBM DS4000 solutions offer you data
access and protection to meet your existing enterprise storage requirements and
prepare for the future.
The DS4500 Storage Subsystem (Machine type 1742, models 90U and 90X)
supports direct attachment of up to four hosts that contain two host adapters each,
and is designed to provide maximum host-side and drive-side redundancy. By using
external Fibre Channel switches in conjunction with the DS4500, you can attach up
to 64 hosts with two adapters each to a DS4500 Storage Subsystem.
Each DS4500 Storage Subsystem contains several removable components, called
customer replaceable units (CRUs), that you can access from either the front or
back of the unit. These CRUs include the battery unit, RAID controllers, storage
subsystem fan, power supplies, fan and communications module, and mini hubs.
The DS4500 Storage Subsystem also has a removable front bezel.
The DS4500 Storage Subsystem functions with at least one external storage
expansion enclosure containing Fibre Channel (FC) or Serial Advanced Technology
Attachment ( SATA) hard drives. The DS4500 Storage Subsystem supports a
maximum of 224 hard drives when the drives are configured using IBM DS4000
EXP700, DS4000 EXP710, DS4000 EXP100, or DS4000 EXP810 storage
expansion enclosures. If the drives are configured using IBM FAStT EXP500
storage expansion enclosures only, a maximum of 220 hard drives are supported.

Attention:
v To attach DS4000 EXP drive expansion enclosures to a DS4500, refer to the
various sections in this IBM TotalStorage DS4500 Fibre Channel Storage
Subsystem Installation, User’s, and Maintenance Guide for the required software
and firmware version, supported drive expansion enclosures and drive loop
cabling rules and instructions. In addition, you must purchase the FC/SATA
Enclosure Intermix premium option to combine DS4000 EXP100s or DS4000
EXP810s with SATA enhanced disk drive modules (E-DDMs) with DS4000
EXP700s, DS4000 EXP710s, or DS4000 EXP810s with fibre channel drives in
the same DS4500 Storage Subsystem configuration. You can also refer to the
IBM System Storage™ DS4000 Hard Drive and Storage Expansion Enclosure
Installation and Migration Guide for additional information on the required version
of the DS4500 controller firmware and the supported combination of enclosure
types intermix behind a DS4500 subsystem.
v The DS4500 controller units are not compatible with the DS4400 or FAStT500
controller units. The DS4500 controller units are keyed to prevent them from
being mistakenly inserted in the non-supported storage subsystem units. Do not
force fit the controller units or the backplane might be damaged.
DS4000 Storage Manager client is also available for the DS4500. This storage
The
management software is designed to help centralize storage management, help
simplify partitioning of the DS4000 series storage into as many as 64 virtual
servers, and strategically allocate storage capacity to maximize storage space.
Operating system support
Microsoft® Windows 2000 Server and Advance Server, Microsoft Windows 2003
Server and Enterprise Edition, Sun®Solaris, IBM AIX, RedHat Enterprise Linux
Server, and SuSE Linux Enterprise Server, HP-UX, Novell Netware, Linux on
POWER and VMware ESX Server are the supported operating systems for host
servers that have mapped LUNs created in the DS4500 with storage expansion
enclosures. See the latest DS4000 Storage Manager host software readme file and
the IBM DS4000 series products interoperability matrix at the following Web site for
additional host operating system support:

Fibre channel defined
Fibre channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre channel is a high-speed data transport technology that
is used for mass storage and networking.
Using a fibre channel arbitrated loop (FC-AL), more than 100 fibre-channel devices
can be supported, compared to 15 small computer system interface (SCSI) devices.
The fibre channel connection speed from the DS4500 to storage expansion
enclosures is either 2 Gbps depending on the type of enclosures to which the
DS4500 is connected, allowing data transfer rates up to 200 Mbps half-duplex and
400 Mbps full-duplex on optical interfaces.
SATA defined
The Serial Advanced Technology Attachment (SATA) interface offers increased data
rate performance over Parallel Advanced Technology Attachment (ATA), while
maintaining the benefits of ATA. S ATA is designed to overcome the performance
barriers that have been forecasted for current parallel technologies while
maintaining the cost-efficiency of Parallel ATA . SATA specifications allow for thinner,
