Several parts, all worth reading.
NO MORE vRAM ENTITLEMENTS! Okay well that’s enough for me but I guess we can review some of the other items.
– vCloud Suites
– New larger virtual machines, up to 64 vCPUs and 1TB of vRAM. New virtual machine format, version 9 which according to the twittersphere should fix quite a few problems in View 5.1 from version 8.
– Updated Virtual Distributed Switch (vDS) proficing config backup and restore, roll back, and LACP.
– vSphere vMotion now works WITHOUT shared storage.
– vSphere replication of VMs over the LAN or WAN with RPO settings as low as 15 minutes.
