IB SR-IOV

IB SR-IOV

[Ernst Gunnar Gran]

Hi

I’m about to start experimenting with SR-IOV and IB (ConnectX-2 G2, HP
DL360p Gen8, E5-2609). Is it OK to just download the latest OFED
release and start playing, or are there any known issues that I should
know of when it comes to SR-IOV with the current release?

Thanks,
Ernst Gunnar

Adding Or Gerlitz who is mlx4_ib maintainer.

Make sure to update the FW to latest FW for your HW from mellanox.com
Upstream kernel has support in SR-IOV and IB, so you can work with it.
If using MLNX_OFED, can look at the release notes.

I would recommend using the IB/RDMA stack from the upstream kernel or 
the one provided with one of the distros that picked SRIOV support from 
upstream into the bits they ship. Note that IB and Ethernet are 
supported for ConnectX VFs, but not yet RoCE.

Or.

Also note you need to do some preparations at the node (bios, kernel 
boot command line) level and card (re-burn the firmware with sriov 
support enabled, see the web or your mellanox rep) level.

Thank you Or (and Amir) for your quick reply and valuable information.
