3.7.5.5 Background Task Priority
The “Background Task Priority” is a relative indication of how
much time the controller devotes to a rebuild operation. The
SAS RAID controller allows the user to choose the rebuild prior-
ity (UltraLow, Low, Normal, High) to balance volume set access
and rebuild tasks appropriately.
3.7.5.6 SATA NCQ Support
RAID controller supports both SAS and SATA disk drives. The
SATA NCQ allows multiple commands to be outstanding within
a drive at the same time. Drives that support NCQ have an
internal queue where outstanding commands can be dynami-
cally rescheduled or re-ordered, along with the necessary track-
ing mechanisms for outstanding and completed portions of the
workload. The SAS RAID controller allows the user to select the
SATA NCQ support: “Enabled” or “Disabled”.
