Asking to confirm my resoning/understanding of B200 M3 with VIC 1240 + expander architecture.
I'm going to implement vSphere 5.1 on running UCS B200 M3 blades equiped with VIC 1240 + mezzanine expanders.
As I understood documentation, all physical links per fabric between host and IOM are automatically agregated by UCS, so if I create only one UCS vNIC per fabric, ESXi should 'see' vmnic with 40 Gbps capability (with 10Gbps limitation for single 'flow').
Saying this other way - there is no need to create 8 vNICs to utilize all 8 physical links?
Have a good day!
