PSP bucket
See preventive service planning bucket.
R_A_TOV
See resource allocation time-out value.
redundancy
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
hr./7 days per week) computer systems and networks.
redundant FRU
SFP LC transceivers, power supplies, and cooling fans that can be removed or replaced
without disrupting switch or Fibre Channel link operation.
remote access link
Connection to a device or program on a computer network via a (geographically) remote
workstation.
remote notification
A process by which a system is able to inform remote users and/or workstations of certain
classes of events that occur on the system. E-mail notification and the configuration of SNMP
trap recipients are two examples of remote notification programs that can be implemented.
remote user workstation
Workstation, such as a PC, using HAFM and Product Manager software that can access the
HAFM server over a LAN connection.
rerouting delay
Enabling rerouting delay ensures that frames are delivered in order through the fabric to their
destination. If there is a change to the fabric topology that creates a new path (for example, a
new switch is added to the fabric), frames may be routed over this new path if its hop count is
less than a previous path with a minimum hop count. This may result in frames being delivered
to a destination out of order since frames sent over the new, shorter path may arrive ahead of
older frames still in route over the older path.
resource allocation time out value
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.
