Buying guide

HPE ROK is a compatibility decision, not just a part number.

Windows Server ROK licences are OEM kits for HPE ProLiant hardware. Before quoting, we check the edition, physical core count, regional route and CAL requirement so the buyer does not end up with a licence path that cannot be used on the target server.

  • Match the ROK region suffix before ordering
  • Confirm Standard, Datacenter or Essentials against the workload
  • Check physical cores, processors and CAL requirements
  • Pair the licence with compatible HPE ProLiant hardware

Regional fit

HPE ROK part numbers vary by region and fulfilment route. UK/EU is the current core market; AMS is an expansion path. We confirm the right regional suffix before quoting.

UK / EUCurrent core marketUse the main product grid below or request a quote with the server location. We confirm the current UK/EU route, stock and fulfilment before pricing.
AMSExpansion routeFor US/Americas deployments, send the server location and fulfilment requirement. We confirm the right regional route rather than assuming the UK/EU suffix applies.

Questions

The things people ask first.

  • Standard or Datacenter — which do I need?

    Standard for most setups. Datacenter only if you need unlimited VMs on that physical server. Standard covers 2 VMs per licence pair. Datacenter is unlimited.

  • Will ROK activate on a Dell or Lenovo server?

    No. ROK is BIOS-locked to HPE hardware. If you need licences for non-HPE servers, ask about standard Microsoft volume licensing.

  • Do you stock 2022 and 2025?

    Yes. Both Windows Server 2022 and 2025 editions are in stock. We'll recommend 2025 for new deployments unless you have a reason to standardise on 2022.

  • How do regional HPE ROK SKU suffixes work?

    HPE ROK part numbers can vary by region and fulfilment route. UK/EU is our current core market, while AMS is an expansion route. We do not assume a suffix from the part number alone; we confirm the server location, customer region and supply route before quoting.

  • Do I need Windows Server CALs with HPE ROK?

    For Windows Server Standard and Datacenter, users or devices accessing the server normally need Windows Server CALs. Remote Desktop Services requires separate RDS CALs if you use RDS. CALs are quoted separately from the HPE ROK server licence unless stated otherwise.

  • How many cores do I need to license?

    Windows Server Standard and Datacenter are licensed by physical cores, with a minimum of 16 core licences per server and 8 core licences per physical processor. If the server has more physical cores than the minimum, we quote the additional core packs needed for that host.

  • Should I choose Standard or Datacenter?

    Standard is usually the first check for low-density or non-virtualised servers. Datacenter is usually considered when the host is heavily virtualised because it includes broader virtualisation rights. The right answer depends on physical cores, processor count and VM count.
