ALSO CALLED: SAN Architecture, Storage Network, Server Area Networks, Storage SANs, Storage Area Networks
DEFINITION: Oversubscription, in a SAN (storage area network) switching environment, is the practice of connecting multiple devices to the same switch port to optimize switch use. Each SAN port can support a particular communication speed and a Fibre Channel switch may offer 1 Gb, 2 Gb, or 4 Gb FC ports. However, because ports are rarely run at their maximum speed for a prolonged period, multiple slower devices  …
