Yes, we have two dual quad-core Intels with heartbeat running and have tested it thoroughly for failsafe. Works great!
You do have to remember that the 'inactive' server does not activate Zimbra or the mail/file/data stores until it is 'active'. Also, when you are working on a server be sure never to log into the inactive server and try to do work like transfers or importing on the active server. It will crash it with a "split brain" error.
Don't have time to go into all the intricacies. Will get back to this thread next week. |
