The ECO Server is an rack mounted appliance type of thing. You can also build out a system on VMWare ESX (I think are the letters), and the main communication platform is a CPCI Shelf, which is a 19" rack mounted horizontal enclosure that can house 2 power supplies, 2 processor boards, and a "spare" hard drive board, and has a backplane to which you can attach local or remote "shelf" cabinets if you have applications that require physical boards. The virtual servers work with virtual boards that you create and then configure just like a real board. They also have an assortment of rack mounted media gateways you can use as well if you only need a small number of analog or trunk ports, etc. The whole system is really quite expandable and flexible, including the ability to have remote standby processors in your remote shelves in case the connection to the main host is severed and a number of other redundancy options.
