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 Lenovo ROK activate on an HPE or Dell server?

    No. Lenovo ROK is OEM-locked to Lenovo ThinkSystem hardware. For HPE ProLiant, see the HPE ROK page. For Dell PowerEdge, ask about Dell ROK or standalone Windows Server.
  • Do CALs come with the server licence?

    No. CALs are a separate purchase. Tell us your user or device count and we will add the correct quantity to the quote alongside the server licence.
