Connecting Physical Disks
After installing the RAID controller, connect physical disks to the RAID controller.
To connect physical disks
1. Select a RAID level that is best suited for your application. For information on RAID levels, see Selecting a RAID Level.
2. Connect the required number of physical disks, as specified in Table 1, to available ports on the controller either directly or through a backplane or enclosure. Refer to the RAID controller HBA or evaluation board documentation for installation instructions.

Note: Installing disks of similar capacity enhances RAID performance.
3. Power-up the physical disks.
Note: To create virtual disks and arrays, only use physical disks connected to a single controller.
