Microsoft Windows Server 2025 Datacenter 16 Core
Microsoft Windows Server 2025 Datacenter 16 Core is the entry-level configuration of the Datacenter 2025 edition, designed for servers with processors totaling up to 16 physical cores. It provides access to all exclusive features of the Datacenter edition — unlimited virtual machines, Shielded VMs, Storage Replica, advanced SDN — combined with the major innovations of Windows Server 2025: native Zero Trust, Hotpatching via Azure Arc, and next-generation Active Directory.
16 Core vs 24 Core Datacenter — which to choose?
The 16 and 24 core versions offer exactly the same Datacenter features — the difference lies only in the number of physical cores covered. The 16 Core version is the most accessible solution to enter the Datacenter 2025 range on compact servers. If your infrastructure has more active cores, Windows Server 2025 Datacenter 24 Core is available as a digital license on Licence24.ch. For environments with moderate virtualization needs, Windows Server 2025 Standard 16 Core offers a more economical alternative.
Who is it for?
Windows Server 2025 Datacenter 16 Core is aimed at IT teams, large organizations, and companies looking to deploy a highly virtualized environment or a private cloud on compact 16-core servers, while benefiting from the latest generation Zero Trust protections. It is the ideal entry point into the Datacenter 2025 range for organizations with high virtual machine density needs on low-core-count machines.
ℹ️ Windows Server 2025 CALs are required for each user or device connecting to the server, regardless of the edition.
