The operating systems supported may not be supported by your server board. See the Tested operating system list for your server board at http://support.intel.com/support/motherboards/server/. To make sure the RAID module supports your operating system, see also the Tested Hardware and Operating System List for the Intel® Integrated RAID Module SROMBSASMR. Usability • Small, thin cabling with serial point-to-point 3.0 Gbps 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 provide: - Online Capacity Expansion (OCE) adds space to existing drive or new drive. See Appendix A: Drive Roaming and Drive Migration Install 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 • 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. Redundancy and Error Handling • In-band and out-of-band SES2. • Enclosure management support. • Fault indicators per drive. • Drive coercion (auto-resizing to match existing disks).
