I’m currently having a question regarding ConnectX4 VPI cards.
I have test environment with connectX4 EDR card, and I would like to test some per VL QoS.
Basically, I have 7 client accessing 1 server, and I would like to dedicate some bandwidth to each client.
My computer are running Centos7.1 with MLNX_OFED_LINUX-3.1-1.0.3 (OFED-3.1-1.0.3).
Regarding the Product description of ConnectX4, the card should support 8 VL, so on the paper, everything is ok.
My HCA details are :
HCA : ibv_devinfo
transport: InfiniBand (0)
state: PORT_ACTIVE (4)
max_mtu: 4096 (5)
active_mtu: 4096 (5)
On the wire, I see that :
So the card is only supporting 4 VL.
What can I do to get 8VL functionning ?
