Hi all, we're in the process of replacing much older UCS hardware (6120's serving B440M2's with M81KR adapters) with 6248's serving B200M4's with VIC 1340 adapters in chassis using 2208XP i/o modules. I'm presenting 10 vNIC's to the servers.
While installing ESXi on the first of the new blades, I noticed that the first five NICs show as:
MLOM Slot: relative bdf 03:00.0
With the number going from 3 through 7. The next five NICs show as:
Chassis slot f; function 0; relative bdf 03:00.0
With the same progression of that bdf number 3 through 7.
I can't find any documentation on why these show up with the different presentation between the first five and remaining five, or if there's any consequence to it from either an efficiency of throughput perspective. From ESXi's perspective they all show the available speed as being a match to the port channel that is serving them on the back end. All our QoS policies are set to either platinum or best effort with line rate limit in case that's relevant, but prior to doing that, the vNIC's that had Bronze defined were showing in vmware as 1gbps cards so I changed them to best effort to get line rate.
Thanks in advance
