FC Replication is not yet scheduled (not for Q1 or Q2 of 09) and it is very time consuming to develop. I realize that 1GbE may not be enough speed per vs FC , we typically see 45MBps and some will install 10GbE directly connected to each other to eliminate the any performance issues.
I believe the Supermicro is the Intel version but not sure, though we should be ok with it and if not we can provide an update for the driver. Additional list below for others that we support.
