Controlling the impact of RAID operations on system performance

You can reduce the impact of RAID operations on system performance by decreasing the speed of the RAID operations.

You can control the speed of the following RAID operations with RAID options:

The speed that you select for each of these operations might affect the overall performance of the storage system. However, if the operation is already running at the maximum speed possible and it is fully utilizing one of the three system resources (the CPU, disks, or the disk-to-controller connection bandwidth), changing the speed of the operation has no effect on the performance of the operation or the storage system.

If the operation is not yet running, you can set a speed that minimally slows storage system network operations or a speed that severely slows storage system network operations. For each operation, use the following guidelines:
