Abstract
Managing data transferred from a local storage device to a remote storage device includes maintaining the data in chunks in cache memory, where data writes to the local storage device begun during a particular time interval are associated with a chunk of data that is separate from other chunks of data and where data is transferred from the local storage device to the remote storage device by transferring a particular chunk after all data writes associated with the particular chunk have completed and after a previous chunk has been acknowledged as being received by the remote storage device and, in response to use of the cache memory exceeding a first threshold, storing data from a first chunk of the cache memory to a local disk. Data writes to the local storage device may be provided by a host coupled to the local storage device.
