Terminology
These are terms used in locating and describing components in an NS2100 commercial system:
Definition
Term
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
rack-mountable 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)
•
Group-Module-Slot-Bay (GMSB)
•
Group-Module-Slot-Port (GMSP)
In an NS2100 system, OSM uses this term to
hierarchically differentiate between each blade element.
Blade complex
An HPE Integrity rx2800 i2 server that contains the
processor element, power supplies, fan assemblies, and
rx2800 i2 blade element
firmware. An NS2100 system includes up to four blade
elements.
On NS2100 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)
