EMC Connectrix B Series DS-8B3 and DS-16B3 Hardware Reference Manual
A software product that allows multiple ports on a switch to create a
logical loop. Devices connected via QuickLoop appear to each other
as if they are on the same arbitrated loop.
Allows initiator devices to communicate with private or public
devices that are not in the same loop.
R
Resource allocation time-out value. The maximum time a frame can
be delayed in the fabric and still be delivered. See also E_D_TOV.
R_CTL
Route control. The first 8 bits of the header, which defines the type of
frame and its contents.
R_RDY Receiver ready. A primitive signal indicating that the port is ready to
receive a frame.
Receiver transmitter timeout value, used by receiver logic to detect
loss of synchronization between transmitters and receivers.
Radius The greatest "distance" between any edge switch and the center of a
fabric. A low-radius network is better than a high-radius network.
RAID Redundant array of independent disks. A collection of disk drives
that appear as a single volume to the server and are fault tolerant
through mirroring or parity checking. See also JBOD.
RAIT
Redundant array of independent tapes.
A device that performs detection and signal processing.
Having multiple occurrences of a component to maintain high
availability (HA).
A fabric that spans across WANs by using protocol translation (a
process also known as tunneling) such as Fibre Channel over ATM or
Fiber Channel over IP.
An optional product for long-distance fabrics, requiring a Fibre
Channel-to-ATM or SONET gateway.
A circuit that uses a recovered clock to regenerate and transmit an
outbound signal.
