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.
