New scalability options for very large virtual machines in Windows Server 2016

Windows Server 2016 Hyper-V introduced several scalability improvements for very large virtual machines (VMs). These features help handle memory-intensive or multi-core workloads more efficiently.

Here are some updated key limits and capabilities:

• Up to 24 TB of physical memory per host (depending on hardware).
• Up to 12 TB of memory per VM (Enterprise or Datacenter editions).
• Up to 240 virtual processors per VM.
• Nested virtualization (Hyper-V inside Hyper-V).
• Discrete device assignment for direct PCIe access.

In addition to higher limits, you can use features like:

• Hot add/remove of memory and network adapters for Generation 2 VMs.
• Production checkpoints that use VSS instead of saved state snapshots.

These make large VM environments more flexible for both testing and production workloads.
