STFs
STFs. See super time factors (STFs).
storage pool. A set of physical disk volumes administered as a set of logical disk volumes.
A logical disk volume can span multiple physical disk volumes. When a logical disk
volume becomes full, more physical disk volumes can be added.
storage-pool file. A file containing a list of disk volumes to be used by an Open System
Services (OSS) fileset. As these volumes are filled, more volumes can be added to the
storage-pool file.
storage subsystem. A subsystem of the HP NonStop™ Kernel operating system that
handles configuration and management of disk and tape devices in G-series release
version updates (RVUs).
storage subsystem manager process. The generic process that starts and manages disk
and tape drives. The $ZZSTO storage subsystem manager process is started and
managed by the $ZZKRN Kernel subsystem manager process through the $ZPM
persistence manager process.
store and forward routing. A form of message routing whereby a router must receive an
entire packet or message before it can start to forward the packet or message to the
next router. Contrast with wormhole routing
.
STP. See shielded twisted pair (STP).
strictly conforming POSIX.1 application. An application that requires only the facilities
described in ISO/IEC IS 9945-1:1990 and the applicable computer language
standards. Such an application must accept any behavior or value described in
ISO/IEC IS 9945-1:1990 as unspecified or implementation-defined and, for symbolic
constants, accept any value permitted by ISO/IEC IS 9945-1:1990.
structured view of the user ID. A view of the HP NonStop™ Kernel user ID, normally used
in the Guardian environment, that consists of either the
group-number,
user-number pair of values or the group-name.user-name pair of values.
subnet. See subnetwork.
subnetwork. A physical network within an Internet protocol (IP) network. Each IP network
can be divided into a number of subnetworks. Within a given network, each
subnetwork is treated as a separate network. Outside the network, the subnetworks
appear as part of a single network. The terms
subnetwork and subnet are used
interchangeably.
subnetwork address. An extension of the Internet protocol (IP) addressing scheme that
allows a site to use a single IP address for multiple physical networks. A subnetwork
address is created by dividing the local part of an IP address into a subnetwork number
(identifying a particular subnetwork) and a host number (uniquely identifying the host
system within the subnetwork). The terms
subnetwork address and subnet address are
used interchangeably.
