[ewg] "To OFED or not to OFED"

Thanks, Faisal.

I also said in the last EWG con-call that the Intel InfiniBand team is committed to OFED and the qib driver backports. We’ll have timelines by the next EWG con-call, if not sooner.

Are meeting minutes going to appear showing what we discussed in the last EWG meeting?

We had already talked in our last ewg meeting that we are working on providing backports support (for NES)  for OFED-3.2. In our next ewg meeting, timelines will be discussed.

It has taken long and as we have been going over the new OFED package and had issues earlier and hopefully we will have the package with all the drivers.

Thanks
Faisal

As a OFED User I would rather it include all the low level drivers.

The problem comes with mixed hardware environments.

If I have to go to Mellanox for their drivers they will insist I run their complete MLNX OFED build.

If I go to Qlogic/Intel they will say the same.   I will then end up with two different OFED distros running which makes our life really difficult.

At least today I can choose,  i'e as these drivers are all in OFED, they are also all in the MLNX_OFED as well so I can choose to run that if I wish.  If they are taken out of OFED,  I won't have that choice.   I like choice.

If the other vendors are not maintaining their drivers and there are know bugs with them, then this should be documented in the release notes and as a last recourse they get dropped from a specific OFED release.     We need to keep the door open to these other vendors,  then the User community can apply pressure to them.

I'll mention this to both the Chelsio and Intel sales teams when they next come knocking at my door to buy their stuff.

EWG is not recommending anything, just soliciting input from the larger

Let's have the discussion on the list first to get people's position on this

before we have any discussions at the board meeting.

Jim,

I believe that we should also include Tziporet and maybe others, therefore Friday will not work for folks from Israel.

Tziporet, I think this is a very important decision. I'd like to make it an agenda item for the Board meeting on Friday. Woody typically participates -- would this be ok?

Thanks, Jim

Hi All,

We started to work on OFED 3.2 and for now we already have the base code working with the new compat framework:

- IB core (all modules)

- IPoIB

- mlx4, mthca - Mellanox drivers

However for the last few months there was no progress on any other low level driver:

- qib - Intel

- nec - Intel

- cxgb3/4 - Chelsio

Since there is no reason to have OFED release for Mellanox only we need to understand the other companies position and commitment for OFED.

We have two options:

- Drop OFED releases all together. Focus our EWG efforts in pushing APIs, testing of the Linux inbox SW stack and driver enhancements for the RDMA technology

- Get real commitment from the vendors on dates to provide the backport support (we can move to kernel 3.3 if we decide this)

Please do your internal consideration and come back with your decision.

 The final decision will be taken in next EWG meeting on May 1.

Thanks

Tziporet & Woody
