Buy Windows Server 2025 Datacenter – maximum scalability for your IT

The flat rate for virtual machines If you make heavy use of virtualization (e.g. with Hyper-V or VMware), the Datacenter edition is the most economical choice. While the Standard edition allows only 2 virtual instances, the Datacenter edition removes this limit entirely. License the physical host (core-based) and create as many VMs as your hardware can handle – at no extra cost.

Exclusive Datacenter features: You will look for these features in vain in the Standard edition:

  • Storage Spaces Direct (S2D): Build highly available, scalable storage systems (software-defined storage) using local hard drives. This enables cost-effective Hyper-Converged Infrastructure (HCI) solutions without expensive external SAN hardware.
  • Software-Defined Networking (SDN): Manage your network flexibly through software. Ideal for cloud providers and complex security policies (micro-segmentation).

What's new in Server 2025: The Datacenter edition also benefits from the technological leaps of the new generation:

  • Hotpatching (via Azure Arc): Apply security updates while the system is running. No reboot, no interruption to your critical VMs.
  • NVMe performance: Up to 90% more IOPS on NVMe storage makes your databases and applications faster than ever.
  • GPU partitioning (GPU-P): Split the power of a graphics card across multiple VMs – perfect for VDI environments.

Core licensing Please note: Windows Server 2025 is licensed per processor core. This offer typically includes the 16-core base license, which is the minimum for a physical server. If your CPU has more cores, you will need additional licenses ("add-on").

System requirements

Identical to the Standard edition, but features such as S2D require considerably more hardware resources (especially RAM and fast network cards).

  • Processor: 1.4 GHz 64-bit with Second Level Address Translation (SLAT).
  • Memory (RAM): 512 MB minimum (at least 64 GB+ recommended for S2D/HCI).
  • Network: At least 1 Gbit/s (RDMA-capable 10/25 Gbit/s cards recommended for S2D/HCI).
  • Security: TPM 2.0 required.
  • Storage: 32 GB minimum.
