Long-distance vMotion is a feature available in VMware vSphere 6.0 that allows virtual machines (VMs) to be migrated over long distances. Long-distance vMotion raises the allowable network round-trip latency that vSphere will allow; this vastly extends the potential migration distance for virtual machinesContent Continues Below
Use cases for long-distance vMotion include data center upgrades, testing, workload balancing and disaster avoidance and recovery. For example if there is a hurricane coming to Florida, a company could use long-distance vMotion to reliably migrate workloads to a data center across the country or to another continent that will not be affected by the storm.
Long-distance vMotion requires the Enterprise Plus license of vSphere.
