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  …

SAN DEFINITION (continued): …  may fan in to a single port to take advantage of unused capacity. For example, a single storage server may not be able to sustain 4 Gbps to a switch port, so two 2 Gb servers or four 1 Gb servers may all be aggregated to that 4 Gb switch port.Oversubscription makes good technical and financial sense. Switch ports can be expensive and dedicating ports one-on-one is not the best use of switch ports and their available bandwidth. Fanning multiple devices into a single port can improve that port's utilization. This saves money and reduces the total number of switch ports that need to be configured …
