Glossary 133
processor Contains the arithmetic and logic, control, and internal memory units that
control the Interface Manager.
protocol A data transmission convention encompassing timing, control formatting, and
data representation.
R
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.
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.
S
SAN Storage Area Network
SCC addressing A menu name. SCSI-3 Controller Commands (SCC) addressing is used to
address SCSI devices attached to the FC interface cards in the Interface
Manager using the SCC logical unit addressing method. In SCC addressing
mode, the Interface Manager 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 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.
