Hi guys
I just got two Mellanox cards from eBay to use those as 10GbE adapters.
However there are two things I don't get.
1. One card shows up as expected with two ports / vmnics. OK the namig of one vmnic is a bit off but at least it's working. Also the card shows some regular MAC addresses.
2. The other card pops up with just a single vmnic and a weird MAC (this is probably normal in the IB world?)

However I would like to find out why one card only shows up with a single port, any ideas? I have seen some similar screenshots floating around but no fix.
Some tips would be really appreciated!

Hi Patrick,
Were you able to find a resolution on this? I am seeing the same issue using ESXi 5.1 U2.
Thanks,
Darren

TLDR: VMware detects some network cards as one PCI-E address with multiple physical nics.
It then uses an algorithm to generate a vmnic alias for the other ports on the card, its a non-issue overall.
1000000 + (pciIndex*100) + p#
I have a connectx-3 dual port card that does the same thing in 6.0 U2.
Heres the VMware article on it with instructions how to change the alias under "Changing the names assigned by the ESXi host":
