Rack and Offset Physical Location
On Integrity NonStop NS-series 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
NS-series 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 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.
Port A connector to which a cable can be attached and which
transmits and receives data.
Group-Module-Slot
(GMS)
A notation method used by hardware and software in NonStop
systems for organizing and identifying the location of certain
hardware components.
NonStop Blade Complex A set of two or three NonStop Blade Elements, identified as A,
B, or C, and their associated LSUs. Each NonStop Blade
Complex usually has four logical processors. A 16-processor
system employs four NonStop Blade Complexes. See NonStop
Blade Complex on page 4-2.
NonStop Blade Element A physical portion of a logical processor containing up to four
processor elements, Each processor element supports a
different logical processor numbered 0-15.
LSU An component of the system that synchronizes the processor
elements of a logical processor and validates all output
operations from each processor element before passing the
output to the ServerNet fabric.
