That's great, if I was wanting to rework the entire mainframe network. My plans were just to route any intra-mainframe IP traffic onto a VSwitch and leave all of the external communication to the current method(s) (dedicated OSA). (You know the adage KISS).
I do like the redundancy with VSWITCH with multiple OSAs though. (Maybe sometime in the future.) Frank M. Ramaekers Jr. Systems Programmer MCP, MCP+I, MCSE & RHCE American Income Life Insurance Co.

Do you have any other surprises? :-) So you have one OSA chpid per z/VSE? To get bandwidth > 1 OSA, you have to run with "Link Aggregation" which requires capability in the physical switch. You could choose instead to create 8 VSWITCHes, each with one OSA or, more likely, 4 VSWITCHes, each with 2 OSAs (1 per for failover).
