ServerNet System Area Network (SAN)
ServerNet System Area Network (SAN). A wormhole-routed, full-duplex, packet-switched,
point-to-point network designed with special attention to reducing latency and ensuring
reliability. The ServerNet SAN provides the communication path used for interprocessor
messages and for communication between processors and I/O devices.
ServerNet Wide Area Network (SWAN) concentrator. A Tandem data communications
peripheral that provides connectivity to a Himalaya S-series server. The SWAN
concentrator supports both synchronous and asynchronous data over RS-232, RS-449,
X.21, and V.35 electrical and physical interfaces.
service-level agreements. Agreements between the operations group and the group’s users
that specify the group’s objectives, requirements, and standards.
Simple Network Management Protocol (SNMP). An asynchronous request/response
protocol (implemented in the Transmission Control Protocol/Internet Protocol (TCP/IP)
protocol suite) used for network management. In the SNMP management framework,
each managed node is viewed as having several variables. By reading these variables,
the managed node is monitored. By changing the value of these variables, the managed
node is controlled.
site update tape (SUT). A tape that contains software and documentation for a particular
release.
SNAX/HLS. A tool that provides a general-purpose, high-level interface by which Tandem
application programs can communicate with intelligent SNA devices and software
products.
SNMP. See Simple Network Management Protocol (SNMP).
SPI. See Subsystem Programmatic Interface (SPI).
SPOOLCOM. A utility program that helps operations personnel monitor and maintain the
spooler and spooler components.
spooler. A set of programs that acts as an interface between users (and user applications) and
the print devices of a system.
SQL. Abbreviation for structured query language. See NonStop SQL/MP.
SQLCI (NonStop SQL/MP conversational interface). A line-oriented terminal interface
that enables a user to enter NonStop SQL/MP statements and commands, format and run
reports, and operate database utilities.
SSG. See SeeView Server Gateway (SSG).
Subsystem Control Facility (SCF). A utility program used to control a variety of
subsystems. For G-series systems, you can use SCF online to configure, control, and
display information about configured objects within SCF subsystems. SCF has been
enhanced to perform many of the functions performed on D-series systems by
DSC/COUP and PUP.
