All operating systems supported by the RAID controller may not be supported by your
server board. To verify compatibility, see the Tested Operating System List for your server
board at http://support.intel.com/support/motherboards/server/.
To make sure the RAID controller supports your operating system, refer to the Tested

Usability
• The card ships with both a standard and a low-profile bracket.
• Small, thin cabling with up to 6.0 Gbps serial, point-to-point data transfer rates
• Support for non-disk devices and mixed capacity drives
• Support for intelligent XOR RAID levels 0, 1, 5, 6, 10, 50, and 60
• Dedicated or global hot spare with auto rebuild if an array drive fails
• User-defined stripe size per drive: 8, 16, 32, 64, 128, 256, 512, or 1024 KB
• Advanced Array configuration and Management Utilities provides:
— Online Capacity Expansion (OCE) adds space to existing drive or new drive.
See Appendix A for limitations on OCE and RAID migration.
— Online RAID level migration (upgrade of RAID mode may require OCE).
— Drive migration
— Drive roaming
— No reboot necessary after expansion
— Load Balancing
• Upgradeable Flash ROM interface
• Allows for staggered spin up, hot-plug, and lower power consumption
• User-specified rebuild rate (percent of system resources to use from 0-100%)
Caution: Exceeding 50% rate may cause operating system errors due to waiting for
controller access.
• Background operating mode can be set for Rebuilds, Consistency Checks,
Initialization (auto restarting Consistency Check on redundant volumes), Migration,
OCE, and Patrol Read.
• Allows mixed connections to SAS targets or SATA II targets
Note: Intel recommends that you carefully assess any decision to mix SAS and SATA drives
within the same virtual drive. Although you can mix drives within the same virtual drive,
Intel strongly discourages the practice. However, you should never mix SAS and SATA
drives within the same enclosure.
