Rack and Offset Physical Location

On Integrity NonStop NS16000 systems, locations of the physical and logical modular

components are identified by:

•

Physical location:

Rack number

Rack offset

•

Logical location: GMS notation determined by the position of the component on

ServerNet

In NonStop S-series systems, group, module, and slot (GMS) notation identifies the

physical location of a component. However, GMS notation in Integrity NonStop

NS16000 systems is the logical location of particular components rather than the

physical location.

Rack and Offset Physical Location

Rack name and rack offset identify the physical location of components in an Integrity

NonStop NS16000 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.

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:
