Glossary
remote notification
A process by which a system is able to inform remote users and workstations 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.
remote user workstation
Workstation, such as a personal computer (PC), using HAFM application and Product
Manager application software that can access the HAFM server over a local area network
(LAN) connection.
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.
ring topology
A logically circular, unidirectional transmission path without defined ends, in which control is
distributed or centralized (D). See also
RS-232
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).
S/390 mode
The mode that is most useful when attaching to IBM S/390 Enterprise servers. See also
systems mode; operating
SAN
See storage area network; system area network.
SBAR
See serial crossbar assembly.
scalable
Refers to how well a system can adapt to increased demands. For example, a scalable network
system could start with just a few nodes but easily expands to thousands of nodes. Scalability
is important because it allows the user to invest in a system with confidence that a business
will not outgrow it. Refers to anything whose size can be changed.
