Required: If you are going to use this configuration, the placement of the blade
servers in the BladeCenter S system is important. Blade servers must be installed
in blade server bays 1, 3, and 5. Blade servers installed in any other blade server
bay will not be able to access the integrated shared storage.

Predefined storage configuration 08
Use predefined storage configuration 08 to implement two blade servers, two SAS
connectivity modules, and up to two storage modules, each with up to six hard
disk drives. Each blade server can access three hard disk drives in each storage
module and all external ports on both SAS connectivity modules.
This configuration has the following characteristics:
v
Each blade server can access up to three hard disk drives in each storage
modules (for a maximum of six hard disk drives if you are implementing both
storage modules).
With this predefined configuration, blade server bays are mapped to hard disk
drive locations in each storage module. The location of the hard disk drives in
each storage module is important. For example, if you install a blade server in
blade server bay 4, it can access only the hard drives located in hard drive bay
2, hard drive bay 4, and hard drive bay 6 of each storage module.
v
The SAS connectivity module in I/O module bay 3 controls access to the hard
disk drives in storage module 1.
v
The SAS connectivity module in I/O module bay 4 controls access to the hard
disk drives in storage module 2.
