ServerNet/FX adapter
fabric for a group. (2) A collective term for both SEBs and modular SEBs (MSEBs)
when a distinction between the two types of SEBs is not required.
ServerNet/FX adapter. A ServerNet adapter that logically extends the ServerNet X and Y
fabrics to other clusters in a Fiber Optic Extension (FOX) ring by using fiber-optic lines.
Two 6740 ServerNet/FX adapters are used, one for the X ring and one for the Y ring.
ServerNet/FX 2 adapter. A ServerNet adapter that logically extends the ServerNet X and Y
fabrics to other clusters in a Fiber Optic Extension (FOX) ring by using fiber-optic lines.
Two 6742 ServerNet/FX 2 adapters are used, one for the X ring and one for the Y ring.
ServerNet LAN Systems Access (SLSA) subsystem. A subsystem of the HP NonStop™
Kernel operating system for configuration and management of ServerNet local area
network (LAN) objects in G-series release version updates (RVUs).
ServerNet wide area network (SWAN) concentrator. an HP data communications
peripheral that provides connectivity to a NonStop 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 connection. A connection between the TSM client software running on a system
console and the TSM server software running on an HP NonStop S-series server. A
service connection can be used only to communicate with the server when the HP
NonStop Kernel operating system is running. A service connection provides a
comprehensive service and maintenance picture of the server and is used to perform
most service management tasks. See also low-level link.
service processor (SP). A physical component of the processor multifunction (PMF)
customer-replaceable unit (CRU) or I/O multifunction (IOMF) CRU that controls
environmental and maintenance functions (including system load functions) in the
enclosure. SPs operate in pairs to provide fault tolerance. The two SPs in group 01 are
designated the master service processors (MSPs). Other pairs of SPs within a system
are called expansion service processors (ESPs).
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your NonStop S-series server. The TSM package
allows you to use the help of a service provider by configuring TSM to support remote
notification and remote access.
shared run-time library (SRL). A collection of procedures whose code and data can be
loaded and executed only at a specific assigned virtual memory address (the same
address in all processes). SRLs use direct addressing and do not have run-time
resolution of links to and from the main program and other independent libraries.
Contrast with dynamic-link library (DLL).
shell. In the Open System Services (OSS) environment, a program that interprets
sequences of text input as commands. A shell can operate on an input stream, or it
can interactively prompt and read commands from a terminal.
