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!

Thank you - I saw the documentation you provided - I can see that there is a 'hardware port-channel' on figures, but I still can't find confirmation that hypervisor will be able to see aggregate speed of physical links (for example table for VIC 1280 shows: 'performance: 10-Gbps line rate per port' - but is it physical port or vNIC ?
The specification of the VIC1240
Number of interfaces: 256 virtual interfaces (approximately 8 are reserved for internal use; other factors such as the OS and hypervisor may limit this number further)
The number of vifs depend on FI model (61xx or 62xx) AND the number of links between IOM and FI (see attachment)
