When vSphere 6.5 was announced I was quite impressed about the features. Gathering more and more hands-on experience so far I am more than happy with it.
One of the new features that can have a real operational benefit hasn’t been documented so far that often (or at least I haven’t seen it anywhere).
Before vSphere 6.5 it was impossible to increase the VMDK size of a DISK that was larger than 2TB when the Virtual Machine was powered on. That was a fact that not many organizations were aware of it until they stumbled upon it.
From an architectural point of view there shouldn’t be many use cases where such a large disk layout would be the best practice. But from an operational point of view for many of my customers this has been a bigger issue.
