5.
If you are creating a redundant RAID array (RAID1, 5, 6, 10, 50), select an
initialization option for the array.
Note: An un-initialized RAID1 or RAID10 array can still provide redundancy in
case of a disk failure. A RAID5 array, however, is not fault-tolerant until initializa-
tion is finished.
6.
Specify a cache policy:
Write-back
When the write-back setting is selected, writes to the array are cached. This will
result in higher performance, but data loss may occur in case of a power failure.
Write-through
When the write-through setting is selected, writes to the array are always passed
directly to the disks. Subsequent reads may still be completed from the cache, if
appropriate.
None
Neither write-back nor write-through cache is used. I/O data will be passed to disks
directly.
7.
Select disks from the Available Disks list.
8.
Enter a capacity for the array, or use the default value (the maximum capacity for
the array).
9.
Click Create. If you have specified an initialization option, the initialization
process will start automatically.
Deleting an Array
To delete an array:
1) Select
"Manage -
Array" from the menu.
2) Click on the
Maintenance
Web RAID Management Interface
button. An Array Information window will appear.
