Which mode of IP over Infiniband does Open-e use? Do they use IPoIB-CM (connected mode)? Because the connected mode is WAY faster than the other implementation of IPoIB (but still not as fast, of course, as SRP or, say, NFS-RDMA). In fact, it almost isn't even worth using Infiniband if you don't use at least IPoIB-CM: http://www.cs.cmu.edu/~wtantisi/ibcl...xperiment.html
The IPoIB-CM (with SDR x4 Infiniband, i.e. 10Gb/s) achieves 500MB/s, while the slower IPoIB achieves only 100MB/s. The theoretical maximum is 1000MB/s for first-generation Infiniband cards, which can be approached using zero-copy protocols based on, say, RDMA.
Also, are any other infiniband cards compatible besides the ones listed in the product compatibility page?
I' have been using infiniband SDR for a week right now.
From The tests I have made, it seems that open-e is using IpoIB because, I haven't got better results thant 100-130 MB/s.
With this kind of performance is not usefull using IB cards on open-e, since you can reach that kind of speed also with giga ethernet.
Is IPoIB-CM available on open-e or it will be ?
We use mellanox cards.
