Metro vMotion.mp4
vSphere 5 introduces a new latency-aware Metro vMotion feature that not only provides better performance over long latency networks but also increases the round-trip latency limit for vMotion networks from 5 milliseconds to 10 milliseconds. Previously, vMotion was supported only on networks with round-trip latencies of up to 5 milliseconds. In vSphere 4.1, vMotion is supported only when the latency between the source and destination ESXi/ESX hosts is less than 5 ms RTT (round-trip time). For higher latencies, not all workloads are guaranteed to converge. With Metro vMotion in vSphere 5.0, vMotion can be used to move a running virtual machine when the source and destination ESX hosts have a latency of more than 5ms RTT. The maximum supported round trip time latency between the two hosts is now 10ms. Metro vMotion is only available with vSphere Enterprise Plus license.
