SVR4
SVR4. System V Release 4, a specific implementation of UNIX. See also System V.
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
SWAN 2 concentrator. See ServerNet wide area network (SWAN) 2 concentrator.
SWAN manager task (SMT). A manager task that is provided as part of the wide area
network (WAN) subsystem. The SMT runs in each communications line interface
processor (CLIP) and provides a variety of management functions such as
coordinating data link control (DLC) and diagnostic task downloads.
SWID. The software identification tool invoked by the SYSGENR program that audits file
identification information about your software.
switch. See HP NonStop™ Cluster Switch (model 6770) and HP NonStop™ ServerNet
Switch (model 6780).
switch enclosure. See cluster switch enclosure.
switch group. See cluster switch group.
switch layer. See cluster switch layer.
switch layer number. See cluster switch layer number.
switch logic board. See cluster switch logic board.
switch mode power supply. A computer power supply that uses a pulse-width modulation
switching inverter and nonlinear current draw characteristics. Switch-mode power
supplies are widely used because of their small size and efficiency.
switch rack. See cluster switch rack.
switch zone. See cluster switch zone.
switched connect. Connection to the Enterprise Storage System (ESS) through a Fibre
Channel switch (FC switch).
symbol. (1) The symbolic name of a value, typically a function entry point or a data location.
In the context of loadable libraries, symbols are defined in loadfiles and referenced in
the same or other loadfiles. (2) Within the ServerNet architecture, the nine or more bits
that encode 8-bit data and protocol commands.
symbolic link. In the Open System Services (OSS) file system and Network File System
(NFS), a type of special file that acts as a name pointer to another file. A symbolic link
contains a pathname and can be used to point to a file in another fileset. Symbolic links
are not included in ISO/IEC IS 9945-1:1990. Contrast with hard link
.
symbolic reference. An occurrence in code or data of the value of a symbol. The symbolic
reference is bound (resolved and made usable) by assigning to it the value of a
