Abstract
An I/O processing stack includes a proxy that can provide processing services for access requests to initialized and uninitialized storage regions. For a write request, the proxy stores write information in a write metadata repository. If the write is requested for an address in an initialized storage region of the storage system, the proxy performs a write to the initialized region based on region information in the write I/O access request. If the write is requested for an address in an uninitialized storage region of the storage system, the proxy performs an on-demand initialization of the storage region and then performs a write to the storage region based on region information provided by the proxy.
