I'm wanting to setup two mail servers in an active / active role, basically meaning both are working, operating, sharing the load. I have a layer-4 switch that I can use for the IP side of things, but I am looking for a solution for the data (mailboxes). I have 2 Dell Servers that each have 5 hard drives and 2 gigabit network cards. Here is what I would like to do, please tell me if it is possible, not possible, or just plain stupid. I would like to have a solution, so that if one server died, no user would notice, I would like to do this without a SAN or External SCSI device. My Idea is to link the 2 servers via IP using a crossover cable and one NIC from each machine. Use the remaining NIC for Internet inbout/outbound traffic. Since each server has 5 drives, I would like to setup some sort of array that DRBD would manage and keep in sync. >From what I have read on the website, DRBD doesn't support write from both nodes. Has this been changed? I think I would need write access from both nodes? If so, who is the author of DRBD? Thanks Duane Cox
