VxRail release 4.5.210, just released, supports vSphere 6.5U2.  See Support Matrix here:  [URL]  I'll let someone else comment on the other questions, as I do not know the answers.
Hi,  I have two queries. Given vSphere 6.7 is now GA and with 6.7U1 due to be release at VxRail 4.7 in Q3 will there be an interim release with vSphere 6.5U2? The reason for asking relates to my second question, with vCenter Enhanced Linked Mode now supported in those two release for embedded vCSA will there be a supported topology coming soon with replication possible between two VxRail clusters without an external vcenter just leveraging the supplied embedded vcsa license in linked vcenter mode?  Thanks Victor
