Setting Adjustable Task Rates

Perform the following steps to set the adjustable task rates.

1.	In the Controller dashboard, select More Actions > Set Adjustable Task Rate.

The Set Adjustable Task Rates dialog appears.

2.	Enter changes, as needed, in the following task rates:

Rebuild Rate – Enter a number from 0 to 100 to control the rate at which a rebuild is performed on a drive when it 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 is 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).
