3-2 Configuring Arrays and Logic Drives

This section provides detailed instructions for configuring arrays and logical drives with the MegaRAID BIOS CU. LSI recommends that you use drives with the same capacity when you create a storage configuration. If you use drives with different capacities in one array, the CU limits each drive to the capacity of the smallest drive.

The number of physical drives in a specific array determines the possible RAID levels that you can implement with the array.

RAID 0 requires from one to eight physical drives.

RAID 1 requires two physical drives.

RAID 5 requires three physical drives.

RAID 10 requires four, six, or eight physical drives.
