ROM. An information storage chip with permanent memory. Stored
information cannot be changed or deleted except under special
circumstances (D). Contrast with
Performance characteristic of a system or product whose integral
components are backed up by identical components to which
operations will automatically failover in the event of a component
failure. Redundancy is a vital characteristic of virtually all
high-availability (24 hours/7 days per week) computer systems and
networks.
RAID. Grouping of hard drives in a single system to provide greater
performance and data integrity. RAID systems have features that
ensure data stored on the drives are safe and quickly retrievable.
A process by which a system is able to inform remote users of certain
classes of events that occur on the system. E-mail notification and the
configuration of simple network management protocol (SNMP) trap
recipients are two examples of remote notification programs that can
be implemented on director-class switches.
An option that ensures that frames are delivered in order through the
fabric to their destination.
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.
A logically circular, unidirectional transmission path without defined
ends, in which control is distributed or centralized (D). See also
ring.
The Electronic Industry Association (EIA)-recommended
specification for asynchronous serial interfaces between computers
and communications equipment. It specifies both the number of pins
and type of connection, but does not specify the electrical signals (D).
