NonStop NS14000 Series Planning Guide (H06.13+)

VIO Enclosure ServerNet Connections
ServerNet connections to the system I/O devices (storage disk and tape drive as well as Ethernet
communication to networks) radiate out from the VIO enclosures for both the X and Y ServerNet
fabrics. (VIO enclosure module 2 provides X fabric connectivity, and VIO enclosure module 3
provides Y fabric connectivity.)
I/O configurations in NonStop NS14000 series systems are flexible, with few restrictions. Those
few restrictions prevent I/O configurations that compromise fault tolerance or high availability,
especially with disk storage as outlined in “Configuration Restrictions for Fibre Channel Devices”
(page 75).
