Robert, 

just in the midst of implementing this. 
I'm using IET on toop of DRBD. The DRBD sync happens on two bonded gigabit 
links. I have yet to install the supervisors. Bottleneck now is the disks 
system. Netperf gives me 180 MB/sec, bonnie++ 120 MB/sec. This is because I 
use a RAID5 on SAS 10K drives currrently. 

Performance obviously will also be related to the number of guests.

Rgds,

Bart
