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), 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.
Write Through – this option raises the level of data security. Data is written directly to
disk when this Cache Policy is enabled.
However, this lowers the overall performance of the array, when compared to Write
Back.
5. Assign hard disks to the array. To add a hard disk to the array, check the box
displayed before each disk’s entry. You can also use the “Select All” button to
quickly select all disks attached to the host adapter.
6. Specify the capacity. Manually enter the desired RAID capacity (in MB). If you
wish to use all available hard disk capacity, leave the “Maximum” entry in place,
and proceed to the next space. If you choose to specify the capacity, make a note
