The disk can be used within with the fully size without any service interruption. Increasing a hard disk from 2.4 to 3TB will just work while the VM is powered on. Important: Hardware Version 13 ( vHW 13) is not required for this to work – therefore just the vSphere platform and not the VM has to be upgraded. The good thing is: With vSphere 6.5 this is not the case anymore. But from an operational point of view for many of my customers this has been a bigger issue. That was a fact that not many organizations were aware of it until they stumbled upon it.įrom an architectural point of view there shouldn’t be many use cases where such a large disk layout would be the best practice. 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).īefore 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.

Gathering more and more hands-on experience so far I am more than happy with it. When vSphere 6.5 was announced I was quite impressed about the features.
