Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP). An asynchronous request-response
protocol used for network management. SNMP originated as a means for managing
Transmission Control Protocol over Internet Protocol (TCP/IP) and Ethernet networks.
slot. A physical, labeled space for a customer-replaceable unit (CRU) or field-replaceable
unit (FRU) that is part of a module. A module contains one or more slots.
slot location. A three-number identifier for a particular slot on a system that consists of the
group number, module number, and slot number. EXAMPLE: 02,01,08 (group 02,
module 01, slot 08).
SLSA subsystem. See ServerNet LAN Systems Access (SLSA) subsystem.
SNMP. See Simple Network Management Protocol (SNMP).
state. (1)The current condition of a device or path to a device. (2) In SCF subsystems, one
of the generally defined possible conditions of an object with respect to the
management of that object, for example, DEFINED, STARTED, and STOPPED.
subsystem. (1) a secondary or subordinate system, usually capable of operating
independently of or asynchronously with a controlling system. (2) A program or set of
processes that manages a cohesive set of Subsystem Control Facility (SCF) objects.
Each subsystem has a manager through which applications can request services by
issuing commands defined by that subsystem. See also subsystem manager.
Subsystem Control Facility (SCF). An interactive interface for configuring, controlling, and
collecting information from NonStop S-series and NonStop NS-Series subsystems.
Subsystem Control Point (SCP). The management process for all Subsystem Control
Facility (SCF) subsystems. There can be several instances of this process. Using the
Subsystem Programmatic Interface, applications send each command for a subsystem
to an instance of this process, which in turn sends the command to the manager
process of the target subsystem. SCP also processes a few commands itself. It
provides security features, version compatibility, support for tracing, and support for
applications implemented as NonStop process pairs.
subsystem manager. A Subsystem Control Facility (SCF) process that performs
configuration and management functions for an SCF subsystem.
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
SWAN 2 concentrator. See ServerNet wide area network (SWAN 2) concentrator.
system area network (SAN). A high-speed network, within a system, that connects
processors to each other and to peripheral controllers. A SAN has the performance of
a massively parallel interconnect, but has distribution capabilities similar to a local area
network (LAN). NonStop S-series servers support the ServerNet system area network
(ServerNet SAN).
