Most Data Center systems are a mixture of LANs and SANs to interconnect the clients to the servers and the servers to the storage.  This requires support for a wide range of protocols including Fiber Channel Protocol (FC), Fiber Channel over Ethernet (FCoE), iSCSI and ethernet amongst others.  Even when protocols are based on the same transport layer (FCoE, ISCI, etc) performance and control requirements often determine the requirement for the storage protocols to be run over their own private network often in fully redundant configuration with fully diverse networks.

SANs in particular are critical to the efficient working of the system and are particularly demanding in terms of throughput and latency.  Traditionally this means that SAN networks are frequently over engineered and over provisioned leading to poor utilization and the requirement for excess capacity including the increased CAPEX and OPEX associated with it. 

Physical layer                          allows a much simpler infrastructure to be deployed with the individual assets being directly connected to the optical fabric where specific configurations can be quickly deployed, updated and re-configured or torn-down in a matter of minutes.  Delivering greater utilization, the ability to instantly deploy resources where they are needed, as they are needed; the network becomes significantly more dynamic and reactive to the demands of the system.  This also allows additional resources to be added, service upgrades, and equipment retirement to be handled seamlessly and in a fully verified process.
