4.6.1 Long-Distance vSphere vMotion
The enabling technology to provide seamless workload mobility to running virtual machines is long distance vSphere vMotion. This capability became available in vSphere 6.0 and enables virtual machines to be migrated across vCenter Server nodes, virtual switches, and physical data centers. The key requirements for long-distance vSphere vMotion are described in the Knowledge Base article
Long-distance vMotion requirements in vSphere 6.0.
But the key requirements are:
• Less than 150 ms latency (RTT) between data centers
• At least 250 Mbps bandwidth available for each long-distance vSphere vMotion operation
So the long-distance vSphere vMotion will not be available to everyone based on physics and geographical dispersion.
Note Long-distance vSphere vMotion operations can be executed either through the web client UI or through the API. Long-distance vSphere vMotion operations executed through the vSphere API present an option to authenticate against separate SSO domains.
