The density range completely depends upon the resources of the server, the contents of a particular containers and finally the desired amount of containers tied to a single piece of hardware. The two most critical resources that enable virtualization are CPU and RAM. The more available processing power, the fewer requirements to offload processing to virtual memory. Parallels Virtuozzo Containers for Linux can achieve a density of 100 containers with minimal content and applications on a 1.46 GHz, 1 GB RAM and 36 GB hard drive. Parallels Virtuozzo Containers for Windows is slightly more limited because the Windows operating system itself takes a large chunk of the available memory.
