2-3 RAID Minimum Drive Requirements
Use Table 2-4 to determine the minimum number of hard drives needed to set up a
RAID environment in SR mode for the AOC-USAS2-L8i add-on card. Use Table 2-5 to
determine the minimum number of hard drives needed to set up a RAID environment in
IR mode for the AOC-USAS2-L8i add-on card. The AOC-USAS2-L8e add-on card uses
HBA and not RAID, so it does not use these modes.
