For Integrity NonStop NS16000 servers, ServerNet communications are controlled by processor switch (or p-switch) modules; one for each of the ServerNet fabrics (represented by X and Y ServerNet Switching blocks in Figure 9-1). P-switches connect input/output components to the NS-series processors. I/O components usually tap into the ServerNet fabrics through ServerNet adapters in IOAMs (represented by Modular I/O blocks in the diagram). These adapters provide the system I/O to fibre channel storage devices and gigabyte Ethernet communications networks. However, P-switches also provide connectivity for legacy I/O through I/O enclosures equipped with IOMF2s (represented by S-Series I/O blocks in the diagram).

Integrity NonStop NS14000 systems do not have p-switches and cannot be connected to legacy NonStop S-series I/O enclosures. For more information, see Integrity NonStop NS14000 ServerNet Connectivity on page 7-3).
