[CentOS] Replacement for Linux-HA (heartbeat) - RedHat cluster?

Hello,

I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available.

The first thing I stumbled upon is RedHat Cluster Suite ( http://www.linuxtopia.org/online_books/centos_linux_guides/centos_cluster_co...), from which I also saw some packages on my CentOS servers.

I've never heard of it before and am just starting to dig its docs, but if someone here can confirm/deny that this is a possible route to take it might save me some time or doubts.

Thanks,
