Creating a RAID Array
After you install the physical disks, you can create the RAID arrays. Before you create a RAID array,
either for the first time, or when you are rebuilding it as a result of failed disks in the array, it is a
good idea to set the Rebuild Priority (
see Setting the RAID Rebuild Priority
) to determine how you
want to allocate the system resources for the rebuild.
NOTE:
When adding disks to an array, we recommend you use the same model of disk with
the same capacity. With the exception of a JBOD, RAIDs are configured to use the
maximum of the smallest disk capacity in the array for each additional disk in the
array. For example, if you install two, 250 GB disks and one 500 GB disk in a
RAID0 array, the total capacity is only 750 GB.
To create an array:
1. From the
Manager Menu
, click
Storage
RAID.
The
RAID
page appears:
2. The available disks appear in the
New RAID Device
table. Select each disk that you want to
include in the array.
3. From the
RAID Level
drop-down menu, click the RAID level of the RAID array you want to create.
4. Click
Add
.
The RAID creation can take some time to complete (depending on the size of the disks and the
selected RAID level). When the build is finished, the array appears in the
RAID Arrays
table. The
disks used in the array are no longer available for creating additional arrays.
