hop count
hop count. The number of routers that form a route between a ServerNet source and
ServerNet destination. Hop count is used to determine the best route. If two alternate
routes have the same time factor, the path with the lower hop count is the better route.
host database. An SQL database maintained for the host system and containing
information about requests, software inputs, snapshots, targets, and profiles.
host system. (1) A computer system that supports very large databases and does batch
processing, usually for an entire network of smaller systems. (2) The central site on
which the Distributed Systems Management/Software Configuration Manager
(DSM/SCM) is managed, the Archive is maintained, and configuration revisions are
built. The host system is also a target system.
HP NonStop™ Cluster Switch (model 6770). An assembly that routes ServerNet
messages across an external fabric of a ServerNet cluster. The cluster switch consists
of a ServerNet II Switch, an uninterruptible power supply (UPS), and AC transfer
switch, and it can be packaged in a switch enclosure or in a 19-inch rack. The cluster
switch is used with star, split-star, and tri-star topologies. See also HP NonStop™
ServerNet Switch (model 6780).
HP NonStop™ Open System Services (OSS). The product name for the OSS
environment. See also Open System Services (OSS)
.
HP NonStop™ Kernel operating system. The former name of the operating system for HP
NonStop systems. See HP NonStop™ operating system user ID
.
HP NonStop™ operating system user ID. A user ID within an HP NonStop system. The
Guardian environment normally uses the structured view of this user ID, which consists
of either the
group-number, user-number pair of values or the
group-name.user-name pair of values. For example, the structured view of the
super ID is (255, 255). The Open System Services (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.
HP NonStop™ K-series servers. The set of NonStop servers having product numbers
beginning with the letter
K. These servers run the HP NonStop Kernel operating
system, but they do not implement the ServerNet architecture.
HP NonStop™ Open System Management (OSM) Interface. Identifies software used to
manage or service HP NonStop servers.
HP NonStop™ operating system. The operating system for HP NonStop systems.
HP NonStop™ S700 server. A special configuration of HP NonStop S-series server that is
limited to one processor enclosure and a maximum of two I/O enclosures. A matched
pair of any model of PMF CRU can be used in a NonStop S700 server.
