RAID subsystem controller alarm tone generator.
• Background Track Priority:
The Raid background Track Priority is a relative indication of
how much time the controller devotes to a background opera-
tion such as rebuilding or migrating. The RAID subsystem allows
user to choose the background priority to balance volume set
access and background tasks appropriately. For high array per-
formance, specify a Low value.
• Terminal Port Configuration:
Speed setting values are 1200, 2400, 4800, 9600, 19200,
38400, 57600, and 115200.
Stop Bits values are 1 bit and 2 bits.
Note: Parity value is fixed at None.
Data Bits value is fixed at 8 bits.
• JBOD/RAID Configuration:
JBOD is an acronym for “Just a Bunch Of Disk”. It repressents a
volume set that is created by the concatenation of partitions on
the disks. For the ARC-5030/6020, it can see the five individual
disks, when you select the JBOD option. User needs to delete
the RAID set, when you want to change the option from the
RAID to the JBOD function.
• Maximum SATA Mode Supported:
Within the subsystem, the SCSI chip acts as a target and 5 SATA
ll bus are connected to the drive. The 5 SATA drive channel can
support up to SATA ll, which runs up to 300MB/s. NCQ is a com-
mand protocol in Serial ATA that can only be implemented on
native Serial ATA hard drives. It allows multiple commands to be
outstanding within a drive at the same time. Drives that sup-
port NCQ have an internal queue where outstanding commands
can be dynamically rescheduled or re-ordered, along with the
