Datacenter and on-premises Fibostack deployments require a minimum of 6 servers to offer virtualization-based functionality.
| Minimum | Recommended | |
|---|---|---|
| Control Domain | 3 nodes | 3 nodes | 
| Virtualization domain | 2 nodes 1 hypervisor for virtual machines and 1 for container host  | 6 nodes 3 hypervisor for virtual machines and 3 for container host  | 
| Monitoring domain | 1 node | 1 node | 
| Total | 6 node | 10 node | 
| Control and monitoring domain servers | Virtualization domain servers | 
|---|---|
| In case of small cluster sizes (less than 10 hypervisors) or at least 12-core Intel or AMD CPU and 128GB RAM per node suffice. For larger clusters, please discuss this matter before Fibostack deployment is started. | Although there are no strictly defined minimum system requirements for virtualization hosts, it is recommended to have 2 x 16-core Intel or AMD CPU (or higher) and 256GB RAM (recommended RAM amount heavily depends on the number of cores in total). | 
There are no strict requirements on networking equipment manufacturers (Juniper and Cisco are preferred).
If using a loadbalancer, an additional internal IP is required.
