ServerNet addressable controller (SAC)
systems; and return reply messages to the clients or requesters. A server process is a
running instance of a server program.
ServerNet addressable controller (SAC). An I/O controller that is uniquely addressable by
a ServerNet ID in a ServerNet system area network (ServerNet SAN).
ServerNet SAN. See ServerNet system area network (ServerNet SAN).
ServerNet system area network (ServerNet 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.
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 HP NonStop S-series server.
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.
storage area network (SAN). A high-speed subnetwork of shared storage devices
connected through a LAN or WAN.
Subscriber Channel (SC). A type of head on a fiber-optic cable in which the pins connect
through a push-pull mating interface.
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 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.
switched connect. Connection to storage using a storage area network (SAN).
