Default Re: Cluster across 2 sites

It is possible if your sites are not too far apart (around 30km or so max, IIRC) and you can run fiber between the sites, to bridge the sync connection. I've seen this working pretty well.

But otherwise, Jim's right, sync is your problem. If you can't get a low-latency connection for the sync link, you need to look into dynamic routing-type scenarios. Of course, this works for failover, but can be a hassle if there are any long-running connections - they will be out of state, and dropped by the backup firewall. Your options depend a bit on what sort of applications you're trying to split across sites, and your architecture.
