management protocol (SNMP) trap recipients are two examples of
remote notification programs that can be implemented on
director-class switches.
remote user
workstation
Workstation, such as a personal computer (PC), using EFC Manager
application and Product Manager application software that can
access the EFC Server over a local area network (LAN) connection.
repeater A device that generates and often amplifies signals to extend
transmission distance.
rerouting delay An option that ensures that frames are delivered in order through the
fabric to their destination.
resource allocation
time-out value
R_A_TOV. R_A_TOV is a value used to time-out operations that
depend on the maximum possible time that a frame could be delayed
in a fabric and still be delivered.
rewriteable optical
cartridge
ROC. A plastic cartridge with a recording medium that uses
magneto-optical read/write technology, and is removable from a
computer and used to store and transport data (D).
RFI See radio frequency interference.
ring topology A logically circular, unidirectional transmission path without defined
ends, in which control is distributed or centralized (D). See also
token
ring.
RISC Reduced instruction set computer. A type of microprocessor that
recognizes a limited number of instructions. A benefit of this is that a
RISC is faster than a complex central processing unit (CPU) which
has more instructions to follow.
ROC See rewriteable optical cartridge.
ROM See read-only memory. Contrast with random access memory.
routed SAN A collection of individual fabrics, connected by intermediate
(multi-protocol) storage networking devices. This SAN functions as a
single large storage network providing any-to-any connectivity,
while maintaining the autonomous nature of each of the individual
fabrics. The storage networking devices that are interconnecting the
various fabrics are called SAN Routers and the process by which
