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. 392
