I have 2 storage servers that use DRBD to sync the disks, with an 
additional 2 servers that connect via iSCSI and mount an OCFS2 
partition. All 4 servers have dual gigabit network cards. Currently, I 
have the 2 storage servers connected via a cat6 crossover cable for DRBD 
- this is on a private network. The other 2 servers connect to the 
storage server through a gigabit switch. Someone recommended bonding all 
of the nics on each server and the ports on the switch and running 
everything over the same network at 2Gbps, rather than 1. My thought was 
that this may degrade the reliability of DRBD by it not having its own 
private communication channel. Am I correct? Or is bonding everything 
together so that it all can run at 2Gbps a good idea?
