Glossary-31
volume
(OSS) environment normally uses the scalar view of this user ID, also known as the
UID, which is the value (group-number * 256) + user-number. For example, the
scalar view of the super ID is (255 * 256) + 255 = 65535.
volume. A logical disk drive, which can be one or two physical disk drives. In a NonStop
system, volumes have names that begin with a dollar sign ($), such as $DATA. See
also mirrored disk or volume.
WAN. See wide area network (WAN).
wide area network (WAN). A network that operates over a larger geographical area than a
local area network (LAN)—typically, an area with a radius greater than one kilometer.
The elements of a WAN might be separated by distances great enough to require
telephone communications. Contrast with local area network (LAN).
wild-card character. A character that stands for any possible character or characters in a
search string or in a name applying to multiple objects. In Subsystem Control Facility
(SCF) object-name templates, two wild-card characters can appear: ? (question mark)
for a single character and * (asterisk) for zero or more consecutive characters.
wormhole routing. A technique for reducing network latency in a router. Packet bytes are
immediately switched to the appropriate output port as soon as they arrive, rather than
accumulated in a buffer until an entire packet has been received. Contrast with store
and forward routing.
X fabric. The X side of the internal or external ServerNet fabrics. See also fabric, external
ServerNet fabrics, and internal ServerNet fabric.
Y fabric. The Y side of the internal or external ServerNet fabrics. See also fabric, external
ServerNet fabrics, and internal ServerNet fabric.
zone. See cluster switch zone.
$ZPM. The process name for the persistence manager process
that starts generic
processes and manages their persistence.
ZSCL. See ServerNet cluster subsystem
.
ZSMN. The subsystem identifier for the external system area network manager process
(SANMAN). See also external system area network manager process (SANMAN).
$ZZFOX. The name of the Fiber Optic Extension (FOX) monitor process in the
ServerNet/FX adapter subsystem.
$ZZKRN. Kernel subsystem manager process. The generic process that starts and
manages other generic processes, some system attributes, and the ServerNet X and Y
fabrics. $ZZKRN is started and managed by the $ZPM persistence manager process.
$ZZSCL. The process name for the ServerNet cluster monitor process.
