The question that got brought up is if a LTM pair (two devices paired) can be in two different data centers with a point to point 100mb line in between?
The request imho is "network-wise" not ...

CirrostratusA few things;
1) I think the failover heartbeat is 1 per second and failover occurs if there are three 'lost' probes in a row. So, latency would need to be very high for this to be an issue. Network failover should work fine over very long distances.
2) Don't forget VXLAN is supported on the box.
3) Note, as far as I'm aware, failover doesn't require L2 adjacency, it's unicast UDP so should work fine if it's routed between devices.
4) I'd agree it's not ideal to split an active and standby in this way.
