Components of the BladeCenter S system
BladeCenter S system components include an advanced management module,
blade servers, I/O modules, storage modules, power modules, fan modules, a
serial pass-thru module, and a media tray.
Front view of the BladeCenter S chassis
Blade servers, storage modules, and the media tray are installed in the front of the
BladeCenter S chassis.
Note: For proper cooling, each bay in the BladeCenter S chassis must have either a
device or a filler installed.
The following illustration shows the front of the BladeCenter S chassis.

Storage modules
You can install a maximum of two storage modules in the BladeCenter S chassis
and each storage module contains hot-swap hard disk drives. A storage module
and the hard disk drives installed in that storage module are commonly referred to
as
integrated shared storage because this storage is integrated in the BladeCenter S
chassis and shared among the blade servers in the BladeCenter S system.
Each storage module can support up to six hot-swap, 3.5-inch hard disk drives. If
you are installing SAS connectivity modules, both SAS and SATA hard disk drives
are supported, and you can use both types of hard disk drives in each storage
module. If you are installing SAS RAID controller modules, you must install SAS
hard disk drives.
Within each storage module, hard disk drives are numbered 1 through 6 from left
to right, and top to bottom.
Note: Each hard disk drive bay must contain either a hard disk drive or a
drive-bay filler.
