bind
The process of configuring unassigned disks into a LUN disk group. Disks can be
bound into one of the following LUN disk groups: RAID 5, RAID 1 (single mirrored
pair), RAID 0/1 (multiple mirrored pairs).
bootware
This controller firmware comprises the bring-up or boot code, the kernel or executive
under which the firmware executes, the firmware to run hardware diagnostics, initialize
the hardware and to upload other controller firmware/software from Flash memory,
and the XMODEM download functionality.
bus
A physical connection between printed-circuit boards in a CPU or a disk array used to
communicate data. See also SCSI-2 bus.
caching
The technique of temporarily storing data in RAM on the disk array controller to
improve performance during an I/O. By using higher-speed RAM whenever possible,
I/Os can be executed faster than accessing the disk.
cascaded FC-AL hubs
One FC-AL hub connected to another FC-AL hub to increase arbitrated loop distances.
Cascaded hubs allow distances up to 500 meters between hubs, or between a hub and a
device.
channel
One of the six SCSI busses connecting the disk array controller enclosure to the disk
enclosures. Each channel is an independent LVD SCSI bus.
channel:ID
The two-part value used to identify a disk module within the disk array when using the
array management tools. The channel value indicates the SCSI channel that the disk
enclosure containing the disk is connected to. The ID value indicates the SCSI ID
assigned to the slot in which the disk is installed.
