All servers must have PXE boot capability and IPMI Remote Management Interface. PXE boot must be activated as a first boot option during Warren setup phase 1 only and can be deactivated afterward.
Supported CPU manufacturers are Intel, AMD and some models of ARM (Intel is preferable).
RAM version is not fixed (both DDR3 and DDR4 are supported for each node type)
Control domain servers - In case of small cluster sizes (less than 20 hypervisors) Xeon x56XX (single or dual CPU) or at least 4-core Xeon E3 and 32GB RAM per node suffice. For larger clusters, please discuss this matter before Warren deployment is started.
Virtualization domain servers - Although there are no strictly defined minimum system requirements for virtualization hosts, it is recommended to have 2 x 8-core Xeon E5 (or higher) and 256GB RAM (recommended RAM amount heavily depends on the number of cores in total).
Networking domain - Juniper EX series switches and MX series routers are prefered. preferred. (for possible device topology, please see diagrams in SDN Setup Plans) For other vendors compatibility, please be sure that routers have following options available and configured:
