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 10 requires four, six, or eight physical drives.
Starting the MegaRAID BIOS CU
Follow these steps to start the MegaRAID BIOS CU:
1. During boot-up, wait for the following message to appear on the screen:
