Terminology
Terminology
Terms specific to an Integrity NonStop NS1000 system that are used in locating and
describing components are:
On Integrity NonStop NS-series systems, locations of the modular components are
identified by:
•
Physical location:
°
Rack number
°
Rack offset
•
Logical location: group, module, and slot (GMS) notation
Rack and Offset Physical Location
Rack name and rack offset identify the physical location of components in an Integrity
NonStop NS-series 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.
Rack offset is labeled on the rails in each side of the rack. These rails are measured
vertically in units called U, with one U measuring 1.75 inches (44 millimeters). The rack
is 42U high with 1U located at the bottom and 42U at the top. The rack offset is the
lowest number on the rack that the component occupies.
Blade Element Group-Module-Slot Numbering
•
Group:
°
In OSM Service Connection displays, 400 through 407 relates to blade
complexes 0 through 7. Each blade complex includes a blade element and its
associated processor.
Example: group 403 = blade complex 3
°
In the OSM Low-Level Link, 400 relates to all blade complexes.
Example: group 400 = any blade complex
•
Module:
°
In OSM Service Connection displays, a module represents either the blade
element or the processor:
°
In an Integrity NonStop NS1000 server, all blade elements are module 1.
Term Definition
blade complex In an Integrity NonStop NS1000 system, OSM uses this term to
hierarchically differentiate between each blade element. See
Blade Complex
on page 4-2.
blade element 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.
