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 for more information about redundancy.)

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 Custom Configuration. 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.

You can include a disk drive's available space in a new logical drive (see Creating a Logical Drive Using Available Segments), or add it to an existing logical drive (see Increasing the Capacity of a Logical Drive).
