Virtuozzo Hybrid Infrastructure works on top of commodity hardware, so you can create a cluster from regular servers, disks, and network cards. Still, to achieve the optimal performance, a number of requirements must be met and a number of recommendations should be followed.
You can run Virtuozzo Hybrid Infrastructure on a physical server or inside a virtual machine. The hardware requirements and recommended number of servers in a cluster depend on the services you will deploy.
