Will ConnectX-3 VPI HBA work with ConnectX-2 VPI HBAs on same IB switch?

Moving forward with cluster build I have been working on for a few months now. The main server is going to be a LGA 2011 Intel Xeon Supermicro GPU server while the 10 nodes will be using older LGA 1366 Xeons with a built in QDR ConnectX-2 VPI HBA in each node motherboard. The switch I plan on using is the SX6012 and I want to use a ConnectX-3 VPI HBA on the main server since it has PCI-E 3.0 slots. I just want to know if it is possible to use QDR ConnectX-3 HBAs with QDR ConnectX-2 HBAs on the same IB switch without any problems. Thankyou in advance.

Thanks again yairi, just wanted to make sure before I moved forward!

Hi Michael,

Shouldn’t be a problem. both cards are fully compliant one with each other and both with all aspects of the IB protocol.
