— 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
— 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.
Redundancy and Error Handling
• SGPIO enclosure management support
