vMotion Enhancements in vSphere 6.0
- Cross vSwitch vMotion (Enterprise Plus, Enterprise, Standard)
- Cross vCenter vMotion (Enterprise Plus only)
- Long Distance vMotionv (Enterprise Plus only)
- Motion Network improvements
- No requirement for L2 adjacency any longer!
- vMotion support for Microsoft Clusters using physical RDMs
VMotion supports 4 concurrent vMotion over 1Gbit networks (or 8 with 10Gbit Ethernet vMotion Connectivity).
vSphere 5.1 enabled users to combine vMotion and Storage vMotion into one operation. The combined migration copies both the virtual machine memory and its disk over the network to the destination host. In smaller environments, the ability to simultaneously migrate both memory and storage enables virtual machines to be migrated between hosts that do not have shared storage. In larger environments, this capability enables virtual machines to be migrated between clusters that do not have a common set of datastores. VMware does not use a specific term for this (shared nothing vMotion) capability as its now considered a standard vMotion capability (no specific license needed).
vSphere 5 enhanced vMotion performance through the ability to load balance VMotion over multiple adapters. vSphere 5 also introduces a new latency-aware Metro vMotion feature that provides better performance over long latency networks and also increases the round-trip latency limit for vMotion networks from 5 milliseconds to 10 milliseconds. (With the Metro vMotion feature the socket buffers are adjusted based on the observed round trip time (RTT) over the vMotion network allowing to sustain maximum throughput number with the higher latency.
