Some companies offer large VPS servers,almost like you're own dedicated, but the mainframe is just ALOT larger than normal VPS main systems. To clarify, you get 2.0gHz of CPU, 1GB of RAM, 80GB Disk. The main PC has a Quad Xeon with 3.0gHz of CPU and 8GB of RAM, much more than a regular VPS host system would need. The purpose of this? management.
