Frequently Asked Questions
How many virtual machines does Datacenter support?
An unlimited number. The Datacenter license does not restrict Windows Server virtual machines, so you can run as many as your hardware allows. This also applies to Windows containers and Hyper-V.
Does hotpatching also work on VMs?
Yes, hotpatching works on both the physical host and virtual machines. You can update the host system and guest VMs without a restart, ensuring zero downtime at every level.
How is it different from Standard 2025?
Datacenter offers unlimited VMs (Standard: 2), Storage Spaces Direct, Storage Replica, Shielded VMs, Network Controller, and Hyper-V containers. Both editions include hotpatching and SMB over QUIC.
Are 5 CALs enough?
5 User CALs cover access for 5 users. You can buy additional CALs separately or choose the 100 Users package, which is significantly cheaper per user for larger teams.
What is GPU Partitioning?
GPU Partitioning (GPU-P) allows a graphics card to be shared across multiple virtual machines. Each VM gets a portion of GPU power, making it ideal for VDI, AI/ML applications, and graphics-intensive environments.
Do I need Azure for hotpatching?
Yes, hotpatching requires the server to be registered in Azure Arc, which is free. Updates are managed through Azure Update Management. Azure Arc itself does not generate additional costs.
How long will Server 2025 be supported?
The expected support period is until approximately 2035, with 5 years of mainstream support plus 5 years of extended support. This gives it the longest support horizon among current server operating systems.
Is the license perpetual?
Yes, this is a one-time payment for the Datacenter license plus 5 User CALs. No monthly subscription applies, and the system and original license remain valid permanently.
