HP NonStop™ Cluster Switch (model 6770)
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™ ServerNet Switch (model 6780). The cluster switch used in the layered
topology. The 6780 switch consists of a switch logic board, a midplane, plug-in cards,
power supplies, and fans.
HP NonStop Open System Management (OSM) Interface. Replacement for TSM as the
system management tool of choice for NonStop S-series servers. OSM provides the
same functionality as TSM while overcoming limitations of TSM. OSM is required for
support of new functionality released in G06.22 and later.
HP NonStop servers. The entire line of HP NonStop servers, including NonStop K-series
and NonStop S-series servers.
hybrid shared run-time library (hybrid SRL). A shared run-time library (SRL) that has
been augmented by the addition of a dynamic section that exports the SRL’s symbols
in a form that can be used by position independent code (PIC) clients. A hybrid SRL
looks like a dynamic-link library (DLL) to PIC clients (except it cannot be loaded at
other addresses and cannot itself link to DLLs). The code and data in the SRL are no
different in a hybrid SRL, and its semantics for non-PIC clients are unchanged.
incremental discovery. Discovery of a NonStop S-series server when the TSM client
software has locally saved information but where there have been configuration
changes on the server since that information was saved.
initial discovery. Discovery of a NonStop S-series server with which the TSM client
software has had no prior contact and for which the TSM client software has no locally
saved information.
installation subvolume (ISV). A subvolume containing files that perform a specific function
during the installation process, such as organizing documentation in a specific location,
providing the components of the HP NonStop™ operating system image (OSIMAGE),
and containing files that are used after the installation process.
I/O adapter module (IOAM). A collection of modular components that provides I/O
connectivity and can include ServerNet switch boards, Fibre Channel ServerNet
adapters (FCSAs), fans, and power supplies. In the IOAM, each module is a logical
entity that represents a single service domain.
I/O adapter module enclosure (IOAM enclosure). The sheet-metal carrier that is installed
in a standard 19-inch rack and contains the IOAM components.
IOMF CRU. See I/O multifunction (IOMF) CRU.
