2.10.1 IBM BladeCenter S Disk Storage Modules
The BladeCenter S supports up to two storage modules, These modules provide integrated
SAS storage functionality to the BladeCenter S chassis.
The storage module’s collection of disk drives are made accessible to blade servers through
a SAS Connectivity Module or SAS RAID Controller Module installed in the BladeCenter S
chassis and SAS expansion cards installed in the blades. The SAS RAID Controller Module
provides RAID 0, 1, 5, and 10 support.
Each of the two storage modules contain up to six 3.5 inch hot-swap hard drives, for a total of
12 internal drives. The storage module supports SAS, SATA, and Near Line SAS (NL SAS)
drives. Intermixing SAS and SATA or SAS and NL SAS drives within the same storage
module is supported.
