Glossary
R_T_TOV Receiver transmitter time-out 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.
RCS Reliable Commit Service. Refers to Brocade-specific ILS Command
Code.
RCS_SFC
RCS Stage Fabric Config. Refers to Brocade-specific ILS Command
Code.
Receiver A device that performs detection and signal processing.
Redundancy Having multiple occurrences of a component to maintain high
availability (HA).
Remote Switch
An optional product for long-distance fabrics, requiring a Fibre
Channel-to-ATM or SONET gateway.
Repeater A circuit that uses a recovered clock to regenerate and transmit an
outbound signal.
Request Rate The rate at which requests arrive at a servicing entity. See also Service
Rate.
Resilience A fabric's ability to adapt to or tolerate a failure of a component
within the fabric.
Resilient Core/Edge
Two or more switches acting as a core to interconnect multiple edge
Topology switches. Nodes attach to the edge switches.
Responder The N_Port with which an exchange originator wants to
communicate.
Retimer
A circuit that uses an independent clock to generate outbound
signals.
