[dpdk-dev] mellanox connectx-2 support

[Vasiliy Tolstov]

Hello. I have some mellanox (ConnectX-2 ?) cards (MT26428) does it possible
to use it with dpdk? Why dpdk supports only X-4 and X-5  cards?
Thanks!

Vasily, 

ConnectX-2 is very, very old card.
We don't support it. 
You can run DPDK on ConnectX-3 Pro, ConnectX-4 /LX and ConnectX-5 NICs.
The best performance and better feature set you will get with ConnectX-5 

Best Regards,
Olga

Probably, provided both an up-to-date firmware version and that ports accept
Ethernet mode configuration [1].

change ports to ethernet.
Does dpdk can work with vfio ?

You can use rdma over Ethernet, AKA ROCE
Mellanox PMDs  don't  need vfio 
I am not sure what you are trying to achieve, you want  to run DPDK on Infiniband?

As i need to use rdma to storage traffic i don't understand benefits of
using ethernet for dpdk and roce for ib over ethernet to storage....

Infiniband?

I have node that serve storage traffic via infiniband and wont to switch
from IPoIB to dpdk based setup but i don't want to drop infiniband from
storage traffic.
