A system integrates an intelligent storage switch with a flexible virtualization system to enable efficient service of file and block protocol data access requests for information stored on the system. A storage operating system executing on a storage system coupled to the switch implements the virtualization system to provide a unified view of storage to clients by logically organizing the information as named files, directories and logical unit numbers. The virtualization system is illustratively embodied as a file system having a write allocator configured to provide a flexible block numbering policy that addresses volume management capabilities, such as storage virtualization, at a finer granularity (e.g., a single block) than that of previous non-flexible storage virtualization schemes. The flexible block numbering policy also yields substantial benefits in terms of increased write efficiency and elimination of storage “hot spots”, as well as a compelling point-in-time read-only data image (snapshot) mechanism.
