— 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.
