The “System Beeper Setting” function is designed for “Disabled” or“Enabled”
the 6Gb/s SAS RAID controller alarm tone.
Background Task Priority
The “Background Task Priority” is a relative indication of how much time the
controller devotes to a rebuild operation. The 6Gb/s SAS RAID controller allows
the user to choose the rebuild priority (UltraLow, Low, Medium and High) to
balance volume set access and rebuild tasks appropriately. For high array
performance, specify a “Low” value.
JBOD/RAID Configuration
JBOD is an acronym for “Just a Bunch Of Disk”. A group of hard disks in a RAID
box are not set up as any type of RAID configuration. All drives are available to
the operating system as an individual disk. JBOD does not provide data
redundancy. User needs to delete the RAID set, when you want to change the
option from the RAID to the JBOD function.
SATA NCQ Support
The 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
dynamically rescheduled or re-ordered, along with the necessary tracking
mechanisms for outstanding and completed portions of the workload. The
6Gb/s SAS RAID controller allows the user to select the SATA NCQ support:
“Enabled” or “Disabled”.
