Terminology
These terms are used in locating and describing components:
DefinitionTerm
Computer system housing that includes a structure of
external panels, front and rear doors, internal racking, and
dual PDUs.
Cabinet
Structure integrated into the cabinet into which
rackmountable components are assembled.
Rack
The physical location of components installed in a modular
cabinet, measured in U values numbered 1 to 42, with 1U
Rack Offset
at the bottom of the cabinet. A U is 1.75 inches (44
millimeters).
A subset of a system that contains one or more modules.
A group does not necessarily correspond to a single
physical object, such as an enclosure.
Group
A subset of a group that is usually contained in an
enclosure. A module contains one or more slots (or bays).
Module
A module can consist of components sharing a common
interconnect, such as a backplane, or it can be a logical
grouping of components performing a particular function.
A subset of a module that is the logical or physical location
of a component within that module.
Slot (or Bay or Position)
A connector to which a cable can be attached and which
transmits and receives data.
Port
A notation method used by hardware and software in
NonStop systems for organizing and identifying the
location of certain hardware components.
Group-Module-Slot (GMS)
A set of two or three NonStop Blade Elements, identified
as A, B, or C, and their associated LSUs. Each NonStop
NonStop Blade Complex
Blade Complex usually has four logical processors. A
16-processor system employs four NonStop Blade
Complexes.
A physical portion of a logical processor containing up to
four processor elements, Each processor element supports
a different logical processor numbered 0-15.
NonStop Blade Element
A component of the system that synchronizes the processor
elements of a logical processor and validates all output
LSU
operations from each processor element before passing
the output to the ServerNet fabric.
