Predefined storage configuration 04
Use predefined storage configuration 04 to implement a single blade server, two
SAS connectivity modules, and up to two storage modules, each with up to six
hard disk drives. The blade server can access all hard disk drives in both storage
modules and all external ports on both SAS connectivity modules.
This configuration has the following characteristics:
v
The blade server has access to all hard disk drives in both storage modules (for
a maximum of 12 hard disk drives if you are implementing both storage
modules).
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.
v
The blade server has access to all external ports on both SAS connectivity
modules.
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.
