SS7TE plug-in card (PIC)
SS7TE plug-in card (PIC). A plug-in card (PIC) used in the 6763 Common Communication
ServerNet adapter (CCSA) that supports the EIA-232, EIA-449, V.35, and X.21
interfaces.
SS7TE2 plug-in card (PIC). A plug-in card (PIC) used in the 6763 Common
Communication ServerNet adapter (CCSA) that supports the E1, J1, and T1 interfaces.
S-SAC. See SCSI ServerNet addressable controller (S-SAC).
SSI log. See System Service Information (SSI) log.
stackable enclosure. An enclosure that can rest on top of another enclosure. A stackable
enclosure is not installed on a frame base. Contrast with base enclosure
.
standby power generator. A turbine-driven or engine-driven generator that provides a
backup source of power to designated loads. Often used to supplement an
uninterruptible power supply (UPS)
in the event of extended utility outages.
star group. One set of X and Y HP NonStop™ Cluster Switches and the ServerNet nodes
(up to eight) that are connected to them. A star group can be thought of as a segment
of a split-star or tri-star topology. A split-star topology can contain up to two star
groups. A tri-star topology can contain up to three star groups.
start mode. An attribute of Subsystem Control Facility (SCF) PROCESS objects that
controls when and if an application process starts in G-series release version updates
(RVUs).
star topology. A network topology in which all nodes are connected to a central hub (HP
NonStop™ Cluster Switch). Each node has its own connection to the network, so a
break in the connection does not affect other nodes in the network. In a ServerNet
cluster, a star topology requires one cluster switch for each external fabric and can
support up to eight nodes. See also split-star topology
, tri-star topology, and layered
topology.
startup file. A file invoked by the local operator or by another startup file that contains
commands to start up system devices, communications lines, and system and
application software. Contrast with shutdown file
.
state. In Subsystem Control Facility (SCF), one of the generally defined possible conditions
of an object with respect to the management of that object. Examples of states are
DEFINED, STARTED, and STOPPED.
static information. Information that represents the set of customer-replaceable units
(CRUs) on an HP NonStop™ S-series system. Contrast with dynamic information
.
static server. In the Guardian environment, a process that runs continuously and provides a
specific service to other processes. A static server differs from a traditional UNIX
demon in that a demon actively looks for tasks to perform. A static server performs
only tasks brought to its attention by a client (requestor) process. See also demon
.
