NonStop NS1000 Planning Guide (H06.08+)

Terminology
These are terms 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 at the bottom of the cabinet. A U is 1.75 inches
(44 millimeters).
Rack Offset
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).
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.
Module
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)
In an Integrity NonStop NS1000 system, OSM uses this
term to hierarchically differentiate between each blade
element. See “Blade Complex” (page 37).
Blade complex
An HP Integrity rx2620 server that contains the PE, power
supplies, fan assemblies, and firmware. An Integrity
NonStop NS1000 system includes up to eight blade
elements.
Blade element
On Integrity NonStop NS1000 systems, locations of the modular components are identified by:
• Physical location:
— Rack number
— Rack offset
• Logical location: group, module, and slot (GMS) notation as defined by their position on
the ServerNet rather than the physical location
OSM uses GMS notation in many places, including the Tree view and Attributes window, and
it uses rack and offset information to create displays of the server and its components. For
example, in the Tree view, OSM displays the location of a power supply in a VIO enclosure in
group 100, module 2, slot 15 in this form:
Power Supply (100.2.15)
Rack and Offset Physical Location
Rack name and rack offset identify the physical location of components in an Integrity NonStop
NS1000 system. The rack name is located on an external label affixed to the rack, which includes
the system name plus a 2-digit rack number.
