Abstract:
Methods and apparatus for supporting cached volumes at storage gateways are disclosed. A storage gateway appliance is configured to cache at least a portion of a storage object of a remote storage service at local storage devices. In response to a client's write request, directed to at least a portion of a data chunk of the storage object, the appliance stores a data modification indicated in the write request at a storage device, and asynchronously uploads the modification to the storage service. In response to a client's read request, directed to a different portion of the data chunk, the appliance downloads the requested data from the storage service to the storage device, and provides the requested data to the client.

Claim (Index 15):
The system as recited in  claim 6 , wherein the inline metadata corresponding to the particular data chunk comprises one or more of: (a) a metadata version identifier (b) a storage device identifier indicating a particular storage device comprising the first storage space (c) a cache entry instance identifier indicative of a most recent cache eviction of the particular data chunk (d) an object identifier of the storage object (e) an object offset indicating a location of the particular data chunk within the storage object, relative to other data chunks of the storage object (f) a device offset indicating a location of the particular data chunk within a storage device comprising the first storage space (g) a state indicator for a caching state of the particular data chunk (h) a data block validity mask indicating validity of one or more data blocks of the particular data chunk stored in the first storage space, or (i) a metadata error detection code.
