Chapter 1. Introduction
The IBM BladeCenter S SAS RAID Controller Module provides a fully-integrated
shared storage solution in an IBM BladeCenter S chassis. This guide contains
instructions for the installation of the IBM BladeCenter S SAS RAID Controller
Modules (SAS RAID Modules) into an IBM BladeCenter S chassis. This guide also
contains information about the interfaces you can use to configure and maintain
your SAS RAID Modules and other associated components you might be using.
Data storage subsystems
Two subsystems are involved in IBM BladeCenter S data storage: the Disk Storage
Module (DSM), and SAS RAID Module. The Disk Storage Module (DSM) is an
enclosure holding up to six Disk Drive Modules (DDMs). There are a maximum of
two DSMs installed in an IBM BladeCenter S chassis.
SAS RAID Module subsystems
The SAS RAID Module includes two subsystems: a RAID Controller subsystem,
and a SAS Switch subsystem. The SAS RAID Modules provide a connection
between the Blade servers and the DSMs that allow you to design storage
configurations and volumes for your data.
In addition, a SAS Expansion Card must be installed in each blade server for the
blades to connect to the RAID Data Storage subsystem and modules.
Firmware updates
The DDM, DSM, RAID Controller, and SAS Switch require firmware updates. Two
methods of updating the firmware are as follows:
v
IBM Storage Configuration Manager (SCM)
The IBM Storage Configuration Manager is a web-based system management
application that you can use to update firmware on the IBM BladeCenter S SAS
RAID Controller Module, DSM, and DDM, as well as manage and configure

devices.
Note:
1.
Firmware update and Raid configuration through IBM Storage Configuration
Manager is NOT supported for DSM_SFF (DSM-12) configuration or mix
configuration (DSM_LFF (DSM-6) combined with DSM_SFF).
2.
Install IBM Storage Configuration Manager on an Ethernet connected
workstation or laptop. For installation and configuration instructions, refer to
the IBM Storage Configuration Manager documentation.
v
SAS RAID Controller Firmware Update Package
The SAS RAID Controller Firmware Update Package is a CLI- based application
package that you can use to update the IBM BladeCenter S SAS RAID Controller
Module, DSM and DDM firmware. You can also write scripts automating
firmware updates of single or multiple IBM BladeCenter S units.
Note:
Install the SAS RAID Controller Firmware Update Package on an Ethernet
connected workstation or laptop running a Windows or Linux operating system.
