I wish it would work that way. But each "service" can run on only one node; I can't do load balancing.
Here's what I'm up to... the idea is to run virtual machines on a group of servers, say maybe two or three VMware guests per machine. VMware is nice, but without any inherent failover features running several servers on a single host presents a dangerous point of failure. So in comes the N+1 cluster. VMs will be put on a SAN or other shared storage media. It's not much, really, and is quite simple to implement using perl or some other script. But there has to be a better, "cooler" way hehehe :) Right now, I'm setting up a two-node version of my cluster. Even if I run it active/active, there's not enough processor power to run all the servers I need. Maybe I'll just go for several pairs of two-node clusters :) -----Original Message----- From: Ariz C.
