Integrity NonStop NS1000 ServerNet Connectivity

ServerNet connections between I/O devices and processors depend on whether the Integrity NonStop NS1000 system has an IOAM enclosure or VIO enclosures. For more information on Integrity NonStop NS1000 systems, see the NonStop NS1000 Planning Guide, NonStop NS1000 Hardware Installation Manual, or the Versatile I/O (VIO) Manual.

System I/O ServerNet Connections

For Integrity NonStop NS16000 systems, ServerNet connections to the system I/O devices (storage disk and tape drive as well as Ethernet communication to networks) radiate out from the p-switches for both the X and Y ServerNet fabrics.

ServerNet cables connected to the p-switch PICs in slots 10 through 13 come from the LSUs and processors. Cables connected to the PICs in slots 4 though 9 connect to one or more IOAM enclosures or to NonStop S-series I/O enclosures equipped with IOMF2 CRUs. Figure 7-3 shows the connections to the PICs in a fully populated p-switch.

For Integrity NonStop NS14000 systems, see Integrity NonStop NS14000 ServerNet Connectivity on page 7-3.Like NS14000 systems, Integrity NonStop NS1000 systems use 4PSEs to provide ServerNet connections between I/O devices and processors. However, there are no LSUs; the 4PSEs connect directly to the Blade Elements. For more information, see the NonStop NS1000 Hardware Installation Manual.

Monitoring the Status of the ServerNet Fabrics

The ServerNet fabrics provide the communication paths used for interprocessor messages, for communication between processors and I/O devices, and (in the case of
