An end-to-end content management and delivery architecture is disclosed which provided for end-to-end content management from a data storage facility to an requestor (5) remotely located. An End-to-End Content I/O Management (ECIM) contains a Global Infrastructure Control (GIC) (4) that monitors the composite load levels at data centers (1, 2, and 3) across network servers, and identifies the best data center from which content request is met. Each data center has a QoS enforcer that monitors content arriving at the data center and controls the entry of all traffic at the data center. Each data center also has a controller, which controls the end-to-end I/O in the local data center. The ECIM allows end-to-end control of the content delivery, scalability provisioning of the application content storage pool to meet service level agreements; dynamic load balancing of the content, and optimization of the I/O resources both locally and across data centers (1, 2, and 3) so as to maximize the service level guarantees with minimum resource usage from application servers to storage.
