When Windows Server 2016 will become generally available later this year, it will be possible to take advantage of hosts with more RAM and more logical processors. Also VMs will support much more RAM and virtual processors than ever before.
With Windows Server 2012 R2, Microsoft didn’t think it was necessary to increase the support numbers for memory and processors. This was based on the absence of customer demand. Of course comparison charts with competing hypervisors will show the difference, but now we can tick off much higher scalability for Hyper-V in Windows Server 2016.
Of course we have to ask ourselves, how much would one host cost that supports 24TB RAM and 512 logical processors.
