NonStop NS14000 Planning Guide (H06.08+)

On Integrity NonStop NS14000 systems, locations of the physical and logical 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
NS14000 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, 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.
This example shows the location of NonStop Blade Element A in rack 1 with an offset of 3U and
NonStop Blade Element B with an offset of 8U:
NonStop Blade Element Group-Module-Slot Numbering
• Processor group: 400 through 401 relates to NonStop Blade Complex 0 through 1. Example:
group 401 = NonStop Blade Complex 1
• Module: 1 through 3 relates to the processor NonStop Blade Element ID A through C.
Example: module 2 = NonStop Blade Element B
