Setting The Rebuild Rate
Does my controller support this feature? See Supported Features.
The Set Rebuild Rate task allows you to change the rebuild rate for a controller.
During a rebuild, the complete contents of a physical disk are reconstructed. The rebuild rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated for rebuilding failed physical disks. At 0%, the rebuild has the lowest priority for the controller, takes the maximum time to complete, and is the setting with the least impact to system performance. A rebuild rate of 0% does not mean that the rebuild is stopped or paused.
At 100%, the rebuild is the highest priority for the controller, minimizes the rebuild time, and is the setting with the most impact to system performance.
On the PERC controllers, the controller firmware also uses the rebuild rate setting to control the system resource allocation for the following tasks:
- Performing A Check Consistency
- Background Initialization. See Cancelling Background Initialization
- Full Initialization. A BIOS setting determines whether a full or fast initialization occurs. See Format, Initialize, Slow And Fast Initialize
- Reconfigure. See Virtual Disk Task: Reconfigure (Step 1 of 3)
