Abstract
Methods and apparatus for WAN-optimized cache population at a storage gateway appliance are disclosed. A read request is received at the appliance from a client. The request is directed to a particular data block of a data chunk of a storage object of a remote storage service. A method comprises, in response to the read request, initiating a first data transfer of the data chunk from the remote storage service to an intermediate device. The method includes determining, based on one or more criteria, contents of one or more other data transfers including a second data transfer from the intermediate device to the appliance, initiating the second data transfer to transmit the requested data block to the appliance, and providing the particular data block to the client from the appliance.
