Thats close to how we did ours, although we did it w/ IPVS load balancing, and currently it's just a raided box for the mail store, no redundancy above that. IPVS doesn't require any kernel modifications per se, nor any software reconfigurations. Just place a load balancer between the real world and your real servers. -- Jesse Keating RHCE MCSE http://geek.j2solutions.net Mondo DevTeam (http://www.microwerks.net/~hugo/) Was I helpful?
