Setting Adjustable Task Rates
Perform these steps to set the adjustable task rates.
-
Select More Actions > Set Adjustable Task Rate on the Controller Dashboard.
The Set Adjustable Task Rates dialog appears.
-
Enter changes, as needed, in the following task rates:
Note: Setting any of these rates to perform faster can result in the system I/O rate being slower.
- 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 occurs.
- Patrol Rate – Enter a number from 0 to 100 to control the rate at which Patrol Read operations are performed.
The Patrol Read function monitors drives to find and resolve potential problems that could cause drive failure. The higher the number, the faster the Patrol Read operation occurs.
- Background Initialization (BGI) Rate – Enter a number from 0 to 100 to control the rate at which logical drives are initialized in the background.
Background initialization establishes mirroring or parity for a RAID logical drive while allowing full host access to the logical drive. The higher the number, the faster the initialization occurs.
- Check Consistency Rate – Enter a number from 0 to 100 to control the rate at which a consistency check is performed.
A Consistency Check operation scans the consistency data on a fault tolerant logical drive to determine whether the data has become corrupted. The higher the number, the faster the Consistency Check operation is performed.
- Transformation Rate – Enter a number from 0 to 100 to control the rate at which transformation of a logical drive occurs.
The higher the number, the faster the transformation occurs.
- 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.
- Click Save to set the new task rates.
