Overview
What's included.
The HPE Windows Server 2025 Standard — 16-Core ROK is an HPE Reseller Option Kit licence for organisations deploying Windows Server 2025 Standard on compatible HPE ProLiant server hardware.
Standard edition is the practical choice for businesses running core infrastructure services, file and print, domain services, application workloads and light virtualisation. When all physical cores are correctly licensed, Windows Server Standard provides rights for a limited number of virtual operating system environments, making it well suited to smaller virtualised estates and traditional physical server deployments.
Key features
- HPE ROK / OEM Windows Server 2025 Standard licence
- 16-core base licence for HPE ProLiant server deployments
- Designed for physical servers and lightly virtualised environments
- Supports common Windows Server roles including Active Directory, DNS, DHCP, file services and application hosting
- CALs are purchased separately based on user or device access requirements
- Additional core packs may be required where the server has more physical cores than the base licence covers
Ideal for
- Small and mid-sized business server refresh projects
- HPE ProLiant tower and rack server deployments
- Domain controllers, file servers and business application servers
- Low-density Hyper-V environments
