Hi All,
I have B420M3 4CPU's w/1240+Port Expander+1280+ IOM 2208+ESXi 5.5
based on my understanding I should get 40GB+40Gb+40GB+40GB=160GB total bandwidth per blade, see attached diagram.
How many vNICs should be created in the service profile in order to achieve 160GB of bandwidth?
if 4 vNICs, how should vNIC/vHBA be mapped to vCONs?
Thanks in advance.

Correct: its 80G full duplex per fabric
my 2c
- between each I/O adaptor and IOM there is a pc of 4 10G links; therefore per stream you have a 10G limitiation
- consider the oversupscription Northbound, IOM - FI, and FI Northbound
- with 2 I/O adaptors, you have 2 vCON's
- if you create vnic's, use manual placement to assign them to fabric A or B, and vCON 1 and 2.
- min number of vnic's is 4 (vCON 1 & 2 Fabric A, (vCON 1 & 2 Fabric B)
