[KLUG Members] Server Mirroring

[Jeremy Leonard]

I'm looking for a solution opensource or comercial to mirror data on two
servers in real time.
Something like Vinca standby server.

My final goal is to have a fault tolerant solution with a database.

Have the database mirrored to two server.
Use HeartBeat to fail over the actual database server application if one
fails.
I plan on having several services running on BOTH systems.
If all the data is mirrored to both systems then the services can be run on
either system.

Anyone know if any such mirroring software?
