version history
v1.0 - vMotion
v2.5 - Storage vMotion
v5.0 - Multi-NIC vMotion, Stun During Page Send (SDPS)
v5.1 - vMotion without shared storage
v5.5 - VPLEX Metro support, IPv6 Improvements
v6.0 - (start with change compute and storage) => vMotion across switching boundaries, vMotion across networking (L3) boundaries (subnets) (aka routed vMotion), vMotion across management boundaries, vMotion across geographical boundaries, Replication Assisted vMotion
vSphere 6.0 is a big step towards vMotion Anywhere

migration time (memory, disk, totla)
switch-over time
impact on guest applications
- application latency and throughput during vMotion
- time to resume to normal level of performance
