Do you need massive Virtual Machines with 240VPs, 16TB of RAM to run databases for Machine Learning, Artificial Intelligence, Data Mining and Analytics?

Windows Server 2016 Hyper-V is your right choice!

After the big announcement of the new VMware Migration Offer for Windows Server 2016 Hyper-V, Microsoft raised the bar one more time with the announcement of the new massive scalability for Windows Server 2016.

Windows Server 2012/2012 R2

Standard & Datacenter

Windows Server 2016 Standard & Datacenter
Physical (Host) Memory Support Up to 4 TB per physical server Up to 24 TB per physical server (6x)
Physical (Host) Logical Processor Support Up to 320 LPs Up to 512 LPs
Virtual Machine Memory Support Up to 1 TB per VM Up to 12 TB per VM (12x)
Virtual Machine Virtual Processor Support Up to 64 VPs per VM Up to 240 VPs per VM (3.75x)

So, based on the feedback throughout the Windows Server 2016 Technical Preview, Microsoft had numerous requests to push Hyper-V scalability to new heights to embrace interesting new scenarios around huge databases and machine learning.
