Amidst all the fun of EMC World, there is some really important news for the VPLEX Metro and VMware community that I wanted to ensure was not lost.
What was supported until now
Prior to this change, the official vSphere Metro Storage Cluster (vMSC) support stance was that VMware HA and vMotion was supported until 5 msec RTT (Round Trip Time). There was an additional wrinkle. vMotion was supported up to 10 msec RTT with your vSphere Enterprise Plus licensing. And VPLEX Metro supported it. However, VMware HA was not supported up to 10 msec RTT.
What has changed
The big change that happened is that now as a part of vMSC both VMware HA and VMware vMotion have now been extended to be supported with VPLEX Metro up to 10 msec RTT. This qualification has been completed with both PowerPath/VE as well as with NMP (Native Multi-pathing) for the non-uniform access mode (i.e. non-cross connected configuration). This support is available starting with vSphere 5.5 and GeoSynchrony 5.2.

Many thanks to the VMware Ecosystem Engineering team as well as key technical leaders on both the VMware and EMC sides for helping drive this. This has been a long time coming.
