I'm using a virtual IP address with heartbeat over an RS232 cable to
provide HA for my application today. I've now been asked to support a
wider range of disaster recovery scenarios.
I'm really hoping to continue using a VIP, but I know that all of the
cluster nodes have to be on the same subnet. I'm an application guy,
not a data networking guy, but I believe that there are several ways to
"extend" a subnet across geographies (VLANs, bridging, etc).
So, has anyone had any success deploying a geographically separated
server cluster with a VIP/Heartbeat using some of this data networking
If so, some high level details on the data networking would be
appreciated, especially any gotchas/hurdles to be aware of.
Thanks in advance,
