Integrated RAID

Use Integrated RAID (IR) where either storage capacity, redundancy, or both of a RAID configuration
are required. Two components of IR are:
Integrated Mirror (IM)

Global Hot Spare

Integrated Mirror

The advantage of an IM is there is always a mirrored copy of the data. An IM provides data
protection for the system boot volume to safeguard critical information such as the operating system
on servers and high performance workstations. An IM supports two simultaneous mirrored volumes,
making an array, providing fault-tolerant protection for critical data. Typically, one of these volumes
is the boot volume. If a disk in an IM fails, the hot swap capability enables the volume to be easily
restored by replacing the failed disk. The firmware then automatically re-mirrors to the replaced
disk.
Global Hot Spare
Each SAS controller can have one global hot spare disk available to automatically replace a failed
disk in the one or two IM volumes configured on the controller. The hot spare makes the IM array
more fault tolerant. Up to two IM volumes are supported per SAS controller plus the hot spare.
