I think the answer would be no. Like HA, FT is designed for the failure of an individual VM running on a ESX host. VMware HA when enabled protects ALL VMs on the cluster, in contrast VMware FT is enabled per-VM and requires an FT-Logging Network with very low latency (2x1GB pipes are recommended for fault-tolerance and low latency) Given the requirements of VMotion, HA, and FT - compatible CPU with the "lockstep" attributes, shared networking and shared storage - its extremely challenging to deliver those as a "stretched cluster" solution. If you looking for a true DR solution for VMware VMs, you should be looking at storage array replication and the Site Recovery Manager product. Regards Mike
