Predefined storage configuration 07
Use predefined storage configuration 07 to implement three blade servers, one SAS
connectivity module, and up to two storage modules, each with up to six hard
disk drives. Each blade server can access two hard disk drives in each storage
module and all external ports on the SAS connectivity module.
This configuration has the following characteristics:
v
Each blade server can access up to two hard disk drives in each storage modules
(for a maximum of four 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 3, it can access only the hard drives located in hard drive bay 3
and hard drive bay 5 of each storage module.
v The SAS connectivity module must be installed in I/O module bay 3 and
controls access to the hard disk drives in both storage modules.
v
All blade servers have access to all external ports on the SAS connectivity
module.
Note: This configuration maps the hard disks to the blade servers and the blade
servers to the external ports on the SAS connectivity module. You will need to use
the LSI Configuration Utility, MegaRAID Storage Manager, or ServerGuide to set
up mirroring.
