The RedHat Load balancing clustering tool (piranha) might looks a bit complex, but in reality, it's just a fancy wrapper around ipvsadm which is the user-space tool for the kernel traffic director. I havent played with Nth module, but ipvsadm is probably more tested. So, we don't have a hardware balancer ? are we searching for a software balancing solution ?

Hey Mike,

RHEL4. We've been meaning to upgrade them to RHEL5 for a while now but they are on a different network segment then the rest of our hardware and as such we cannot easily pxe boot them (it would involve a request to the SOC). I'm going to put a plan together to do this and minimize any risk that may come up. The main benefit being mod_proxy_balancer. I'm still hoping we can acquire some hardware balancers but this will help us limp along for this release :)
Have you looked at using iptables for load balancing? Nth module could help with this.
Honestly I didn't. I thought about using some of the RH clustering suite but it will add a bit more overhead then we want for our current environment. Do you have a link to some good documentation for iptables based load balancing?
