suggestions for building HA cluster?

[rickrude11]

Hey there

I have just 4 ubuntu linux servers that are running on ESXi - postfix, mysql, web, ldap - which I would like to replicate to another site.

I have a second site that I have bridged, so IP addressing can remain the same for simplicity.

Ideally, I would like to replicate the Virtual machines at a block level. I know this is impossible on ESXi, but I am willing to change platforms (virtualbox?)

I had a similar set up years ago using heartbeat and drdb on a centos box with vmware server. It worked well for the most part, I was able to shut one down and the other would just take over, but I was wanting to see what other options were around these days.

Any ideas or criticisms welcome. Second option is to to traditional replication with dodgy rsync scripts.

cheers.

as to Clustering Software, here is one, I haven't used it myself, but still worth to take a look at:
