NonStop NS2200 Series Planning Guide

DefinitionTerm
In a NonStop NS2200 series system, OSM uses this term
to hierarchically differentiate between each blade element.
Blade complex
A DC-powered HP Integrity rx2800 i2 server that contains
the PE, power supplies, fan assemblies, and firmware. A
rx2800 i2 blade element
NonStop NS2200 system includes up to four blade
elements.
On NonStop NS2200 series 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 a NonStop NS2200
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). A 36U rack or seismic rack has
36U with 1U located at the bottom and 36U at the top. A 42U rack has 1U located at the bottom
and 42U at the top. The rack offset is the lowest number on the rack that the component occupies.
The rack offset is the lowest number on the rack that the component occupies.
