Thanks for the replies. As I suspected, there doesnt appear to be anyone running IB with Open-E - mainly because its just too slow using IPoIB and iSCSI. I'm guessing they dont support SRP because it isnt a recognised standard. Its a shame because the benefit of using RDMA over IB coupled with the low cost of the hardware makes for very exciting possibilities when building a SAN on a budget.

IB is faster and much cheaper than 10GbE. All the drivers and software required to run IB/SRP initiators and targets on Linux are fully available. Its just a shame that no-one has yet bundled it all into a software package such as Open-E. When someone finally does this, I'm sure they will make a lot of money.

We are committed to using IB in this cloud and building all the hardware ourselves - so its just a case of spending the time looking at the OFED and SCST target drivers and going through an extended period of configuration and testing to get things just right.
