Balancing disk pool data

You can balance the data in your disk pool using various balance options.

You can start or stop the balancing of data in disk pools by selecting one of several balance options.

*CAPACITY moves the data in the disk pool so that the disk units in the disk pool are approximately the same percent full.
Note: If there are Solid State Disks (SSD) and High Density Disk (HDD) disk types in the disk pool, the data on the SSDs is balanced among the SSD disks, and the data on the HDDs is balanced among the HDD disks.
*HSM moves the data in the disk pool so that the frequently used data is moved to the SSD units, and the infrequently used data is moved off the SSD disks onto the HDD disks.
*USAGE moves the data in the disk pool so that the frequently used data is evenly spread over all of the disk units in the disk pool.
