Including Different-sized Disk Drives in a Logical Drive

You can combine disk drives of different sizes in the same logical drive. If the logical drive includes
redundancy, however, the size of each segment can be no larger than the size of the smallest disk drive.
(See Selecting the Best RAID Level
Note: We recommend that you do not combine SAS and SATA disk drives within the
same logical drive. maxView Storage Manager displays a warning if you try to create
a logical drive using a combination of SAS and SATA disk drives.
To create a logical drive with disk drives of different sizes, follow the instructions in
on page 41. When the wizard displays the RAID Members panel, select different size drives, as shown
in the figure below, then complete the wizard.
When the logical drive is created, check its resources on the Storage Dashboard: it should appear similar
to the next figure, where a RAID 5 logical drive includes two disk drives of one size and one of another.
