3. Enter changes, as needed, to the following task rates:
Rebuild Rate. Enter a number from 0 to 100 to control the rate at which a rebuild will be performed on a
—
drive when one is necessary. The higher the number, the faster the rebuild will occur (and the system I/O rate
may be slower as a result).
Patrol Rate. Enter a number from 0 to 100 to control the rate at which patrol reads will be performed. Patrol
—
read monitors drives to find and resolve potential problems that might cause drive failure. The higher the
number, the faster the patrol read will occur (and the system I/O rate may be slower as a result).
Background Initialization (BGI) Rate. Enter a number from 0 to 100 to control the rate at which virtual
—
drives are initialized "in the background. " Background initialization establishes mirroring or parity for a RAID
virtual drive while allowing full host access to the virtual drive. The higher the number, the faster the
initialization will occur (and the system I/O rate may be slower as a result).
Check Consistency Rate. Enter a number from 0 to 100 to control the rate at which a consistency check is
—
done. A consistency check scans the consistency data on a fault tolerant virtual drive to determine if the data
has become corrupted. The higher the number, the faster the consistency check is performed (and the
system I/O rate may be slower as a result).
Reconstruction Rate. Enter a number from 0 to 100 to control the rate at which reconstruction of a virtual
—
drive occurs. The higher the number, the faster the reconstruction occurs (and the system I/O rate may be
slower as a result).
4. Click Ok to accept the new task rates.

Changing Power Settings

The RAID controller includes Dimmer Switch technology that conserves energy by placing certain unused drives into
Power-Save mode. In Power-Save mode, the drives use less energy, and the fan and the enclosure require less energy
