This is a demonstration of EMC VPLEX supporting vMotion over distance use cases.
In the demonstration - note that the underlying storage is simultaneously read/writeable on both sides (evidenced by the two Oracle VMs supporting Swingbench workloads accessing the same datastore).
For the 100 smaller VMs, each vMotions between the clusters 100km apart only took 2.4 seconds, and like all vMotion operations is totally non-disruptive.
This has been tested at much higher scales. EMC VPLEX can scale up to 4 storage engines (8 cluster nodes) on each side - up to thousands of disk devices.
vMotion over distance or stretched vSphere ESX Clusters requires the use of technology like EMC VPLEX and the ability to interconnect the datacenter networks, using something like Cisco's Datacenter Interconnect (DCI) family of technologies.
Should be a 2 gig link.

what is the link between 2 clusters when vm was vmotioned, 100 MBps? I am curious if you have tested ms cluster this way since you can share the disk over wan?
