Note
The number of hard disk drives in the array
determines the RAID levels available for the
array.
Ÿ
If the array contains one hard disk drive, you
can select only RAID level-0 for the logical
drive.
Ÿ
If the array contains two hard disk drives,
you can select RAID level-0 or RAID level-1
for the logical drive.
Ÿ
If the array contains three or more hard disk
drives, you can select RAID level-0, RAID
level-1, or RAID level-5 for the logical drive.
5. Enter the Requested Space in the entry field.
The ServeRAID program uses the maximum available
space for the selected RAID level to calculate the
default value that it assigns.
Note
The actual logical drive size might be slightly
different from what you type in the Requested
Space field. The RAID level and the number of
hard disk drives determine the size of the logical
drive. For example, a disk array consisting of
three, 1 GB hard disk drives with a requested
RAID level-0 logical drive of 1000 MB will actually
contain only 999 MB because the data is striped
across all three drives, with 333 MB on each
drive.
6. Select OK to create the disk array.
Deleting disk arrays:
To delete a disk array:
1. Select the on the Tool Bar or select Manage
Disk Arrays from the Advanced pull-down menu;
then, select Delete Disk Array. A screen similar to
the following appears.
Deleting a disk array deletes all logical drives that are defined
in that disk array. All data and programs on the logical drives
in the disk array will be lost during this procedure.
