Example 16-Processor Triplex System Cabling
the two-controller, two-disk drive enclosure configuration shown in detail in Two
FCSAs, Two DDEs, One IOAM Enclosure on page 4-24.
For details and instructions on connecting cables as part of the system installation,
refer to the NonStop NS-Series Hardware Installation Manual.
Example 16-Processor Triplex System Cabling
The next two illustrations show an example 16-processor triplex system with four
cabinets. The first illustration shows the cabinets that house the slice, LSU, and
p-switch enclosures, with the second illustration showing the two cabinets that house
the IOAM enclosures and disk drive enclosures.
This illustrations are simplified and conceptual representations of the X and Y
ServerNet cabling between the slice, LSU, p-switch, and IOAM enclosures. For clarity,
power and Ethernet cables are not shown. For cable-by-cable interconnect diagrams,
see Internal ServerNet Interconnect Cabling on page 4-4.
The example system represents the cabling between cabinets using overhead cable
handling equipment rather than under-floor cable routing.
