From EMC whitepaper:
USING VPLEX™ METRO WITH VMWARE HIGH AVAILABILITY AND FAULT TOLERANCE FOR ULTIMATE AVAILABILITY
…VPLEX can support up to 5ms of round trip time latency where VMware HA solutions can be deployed, however only 1ms between clusters is supported for both VPLEX cross cluster connect topologies as well as VMware FT topologies.
Answer is < 1ms
