Cages and cabinets delineate the type of space that a colocation provider will convey to a customer in a retail colocation model. Cages are moveable walls on top of raised flooring to separate one customer's space from that of another. Cabinets, on the other hand, are typically lockable individual racks to house server, storage or communications equipment. Cages are typically for larger retail colocation customers, while cabinets can come in 1/3, half or full sizes. Both are used in shared room environments (other customers).
