3) When creating a Redundant Array (RAID 1, 5, 10, 50), specify an
initialization method. Select Background of Foreground from the
drop down menu:
No Initialization: Not recommended for most configurations. This option
will not build parity. Select this when testing storage. The array must be
verified manually if this option is selected
Foreground: The RAID initialization process will be set as high priority.
The array cannot be utilized this procedure is complete, but the build
process will take considerably less time, as the host adapter will dedicate
it’s resources to completing this task. This is most secure option.
Background: This option lowers the priority of RAID initialization. This
option will start to build parity like the Foreground option, but at a lesser
rate of speed. This option allows the array to be accessed immediately.
However, as a result, protection against data loss is much lower
compared to the Foreground option.
4) If you are creating a Redundant Array (RAID 1, 5, 10, 50), specify the
array’s Cache Policy. If you are creating a JBOD or RAID 0 array,
skip to step 6. Select Write-Back or Write-Through from the drop
down menu:
Write Back – this setting is best for optimal transfer rates, and fully
utilizes the available memory to enhance read and write performance.
However, this option raises the risk of data loss in the event of hardware
failure.
