Hi,

The card you have is an ETH only card and not a VPI card (IB/ETH)

[pavel_v1]

Thank for so sad answer.

So, I can’t connect it with InfiniBand switch? Only with other such card? And could you say what is its bandwidth?

[dwaxman]

It is a 100Gb Ethernet card.

It cannot be used in an infiniband setup.
