Well, LVS does not nescessarly need a third machine. See: http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS- HOWTO.localnode.html#two_box_lvs I would use two machines and put the following software on the machines: - Mail Application: potfix, cyrus - Load Balancer: LVS, ldirectord - pacmaker for the high availability. then you have high availabiliy, load balancing and nearly unlimited scalability. ldirectord integrates very nicely into a pacemaker cluster. Please feel free to contact me for further question.
