FASTORA DAS-315SA Disk Array

RAID Rebuild Priority

The “Raid Rebuild Priority’ is a relative indication of how much time the

controller devotes to a rebuild operation. The RAID subsystem allows user to

choose the rebuild priority (low, normal, high) to balance volume set access

and rebuild tasks appropriately.

Terminal Port Config.
