I've tested sheepdog, is absolutely fantastic.
But... is slow (without cache, tested on 1 gbps eth).
The idea... if I use a low cost infiniband card (HP, 2 ports, 140 $), tcp over IB, can I increase performance ?
HD storage on 3 nodes make 200 Mbyte/sec in local, in this case (3 nodes on sheepdog), the bottleneck is the 1 gbps link ?
If so, infiniband should be the best choice...
