You'll probably be better off looking at an infiniband-based solution. I just picked up two dual port Mellanox 10G 8x PCIe cards and a 1m cable for under US$200. Aside from just bandwidth, the other advantage 1/4 of the latency of a gigabit ethernet setup, although my suspicion is that you might lose some of this advantage after your packets traverse through the IPoIB layers. As I'm still waiting on my ebay purchases to arrive, I might come to regret this advice once I actually try to set it up and configure it. *Caveat Emptor.* Mike On Thu, May 13, 2010 at 11:06 AM, Bart Coninckx <bart.coninckx at telenet.be>wrote: > On Thursday 13 May 2010 17:01:46 Bart Coninckx wrote: > > Hi, > > > > would it make sense to use four bonded gigabit NICs when the DRBD storage > > is, let's say, a RAID 5 on 10K RPM SAS drives?
