Lenovo Thinkserver RD650MLK with 4* Intel x520-DA2 adapters - all NIC's are not working within vSphere 6.x

Hi Guys,

We're encountering a strange problem, which involves 3* servers with the same HW as in the title (Lenovo Thinkserver RD650MLK with 4* Intel x520-DA2 adapters - 3* PCIe, 1* on board - total of 8* 10GbE SFP+ based ports).

After installing vSphere 6.x on all the servers, we're encountering the same problem on all of them; all of the NIC's are viewable within the vCenter, BUT only the 1*on-board x520 is actually working. The rest of the PCI-e cards are not working at all (with or without transceiver connected light).

Elimination which we've tried:
    Using same transceivers (from the External x520) on the internal - all are working well.
      We're about to install the a new OS (MS Win server based) - so we'll be able to eliminate it on the OS level as well

      We would appreciate your advice, since it's a new production environment which is critical to our customer.

      Thanks!

      1. Are you using the correct version of ESXi, e.g. the OEM version from Lenovo, which contains all the drivers ?

      see here

      2. Is the server firmware, storage controller firmware, and network firmware up to date ?

      3. Is this server on the HCL ?

      4. Install additional drivers if required.

      You might also check that BIOS is up to date. That was a issue at one client when one server out of two did now work properly.

      Do you have Lenovo Support?  Call them and lodge a case.

      Hi guys,
      Thanks for assisting !

      The problem was solved by taking out all the x520 PCI cards, are replacing them with 2* x710 cards (QP).
      Seems pretty mysterious to me..

      Anyone can take a guess?

      You would have to ask Lenovo. Some hardware compliance issue somewhere.
