Hello, we reading this manual for vma:
For example there is ““Dummy Send” feature is supported in hardware starting from ConnectX-4 NIC”
and “Multi Packet Receive Queue: Mellanox ConnectX-4 LX / ConnectX-5 or above.”
Will it work on connectx-4 lx? or only starts from connectx-4?
Which card “better”?
Thx for your cooperation, Alex.
If you are trying to use Multi Packet Receive Queue with VMA API it’s focused on Media use cases.
I think it will be best if you be more specific with your use case and needs and we can direct you how it can be achieved.
I cant find info about working it on X-4 or X-4LX, there is only vma manual for 8.4.* version, not higher.
you are referring to two different features:
- Dummy send is supported on ConnectX-4, ConnectX-4LX and ConnectX-5
- Multi Packet Receive Queue is supported on ConnectX-4LX and ConnectX-5
These two features are used for different use cases.
The Dummy send is been used for low rate traffic - usually in the financial market.
The Multi Packet Receive Queue is been used for Media use cases.
I hope this answers your question.
Thanks for your answer.
So does it mean that Explicit Ring Polling doesnt supported by ConnectX-4LX ?
It’s for market, but we want try Multi Packet Receive Queue too.
Can you answer about Explicit Ring Polling?
We interested in it much more than i MPRQ
In order to get data directly from the Ring you can try our SocketXtreme feature.
Thank a lot for your cooperation
