For those that are looking for a little extra networking juice saw this for $1000, QDR (40gbps) Infiniband. 36 ports. If you were to do a big QDR build out, this might be cost effective. Power consumption would probably be a bit scary though.
Could be ridiculously fast storage network... but I've never actually played with iscsi over infiniband. I have got iscsi over ipoib working, but that adds quite a bit of latency and really doesn't seem worthwhile.I have had this in my ebay watch list for a while. I cant justify it right now though. Sad.
Thanks! I'll post more details as the gear starts coming in.Feel free to start a thread here on the build and welcome to the forums!
