DEV/QA/TEST Implementation

We are indeed using the LAB version: LTM, Lab, V with 11.2.1HF1. There are two virtual LTM's with network (unicast) failover. We have two traffic groups with one running on the Active unit and the other on the Standby, allowing us to fail over traffic groups independently.

Snapshots on the ESX server have been disabled; unexpected failovers can happen if the network interfaces are quiesced for too long. We have an external process that downloads ucs archives and imports them into rsnapshot so having ESX snapshots isn't necessary.

The only problematic issue we've come accross is related to vMotion. F5 has sensible precautions concerning potential traffic disruptions during a vMotion. For us, right after one of these magical events the trust between the two virtual LTM's exploded into tiny little shards. It's probably best pinning the LTM's to specific ESX servers to avoid it altogether.
