RAID Redundant Array of Inexpensive Disks

receiver A terminal device that includes a detector and signal processing.

Reset SCSI For a specific SCSI bus, the host clears all inputs and outputs and then resets

the bus and all the devices connected to it.

responder The logical function in an N_Port responsible for supporting the exchange

initiated by the originator in another N_Port. A FC responder is comparable to

a SCSI target. The 4x50 is often the responder.

router A device which selectively forwards data between networks based on

administratively defined preferences. The forwarding decision is based on

paths between address mappings among dispersed devices. Storage Routers

focus on the SAN environment. See Storage Bridge.

Router-to-Router Configuration involving at least two storage routers where one router is in

Initiator Mode and another in Target Mode.

SAN Storage Area Network

SCC addressing A menu name. SCSI-3 Controller Commands (SCC) addressing is used to

address SCSI devices attached to the 4x50 using the SCC logical unit

addressing method. In SCC addressing mode, the 4x50 will respond to FCP

commands as a SCC controller device.

SCSI Small Computer Standard Interface. An industry standard for connecting

peripheral devices and their controllers to an initiator.

SCSI adapter A 16-bit fast/wide differential or 8-bit narrow single-ended physical

connection between the 4x50 and the SCSI devices. Each SCSI adapter

supports up to sixteen (for fast/wide) or eight (for narrow) SCSI devices,

including itself.

SCSI addressing A SCSI adapter supports up to 16 devices, including itself. Each device has its

own unique SCSI address. The SCSI address of a device dictates the device's

priority when arbitrating for the SCSI bus. SCSI address “7” has the highest

priority. The next highest priority address is “6” followed by 5, 4, 3, 2, 1, 0,

15, 14, 13, 12, 11, 10, 9, 8, with “8” being the lowest priority address.
