Background Task Priority:
The Background Task Priority indicates how much time and system resource the RAID
controller devotes to a background task, such as a rebuild operation. The RAID
subsystem allows user to choose the background task priority (High 80%, Medium 50%,
Low 25%, and Ultra Low 5%) to balance between background task process and
Volume Set access. For high RA I D subsy stem performance, specify a low value.
JBOD/RAID Configuration:
The RAID subsystem supports JBOD and RAID configuration.
