segmented E_Port
Expansion port (E_Port) that has ceased to function as an E_Port within a multiswitch fabric
due to an incompatibility between the fabrics that it joins. See also expansion port.
serial crossbar assembly
(SBAR) — Responsible for Fibre Channel frame transmission from any director port to any
other director port. Connections are established without software intervention.
SFF
(small form factor) — A type of Fibre Channel connector). See also fiber port module card.
simple network management protocol
(SNMP) — A protocol that specifies a mechanism for network management that is complete,
yet simple. Information is exchanged between agents, which are the devices on the network
being managed, and managers, which are the devices on the network through which the
management is done.

SNMP community
Also known as SNMP community string. An SNMP community is a cluster of managed
products (in SNMP terminology, hosts) to which a server or managed product running the
SNMP agent belongs.
SNMP community name
The name assigned to a given SNMP community. Queries from an SNMP management station
to a device running an SNMP agent will only elicit a response if those queries are addressed
with the correct SNMP community name.
SSP
See system services processor.
storage area network
(SAN) — A high-performance data communications environment that interconnects computing
and storage resources so that the resources can be effectively shared and consolidated.
subnet mask
Used by a computer to determine whether another computer with which it needs to
communicate is located on a local or remote network. The network mask depends upon the class
of networks to which the computer is connecting. The mask indicates which digits to look at in
a longer network address and allows the router to avoid handling the entire address.
switchover
Changing a backup FRU to the active state, and the active FRU to the backup state.
