  • Patent number: 9727278
    Abstract: An emulation mitigation module is configured to mitigate emulation of legacy write requests on advanced disk devices using cached data stored in a cache memory of a storage system. A legacy write request may comprise write data blocks formatted in a legacy sector size while an advanced disk device may be formatted in an advanced sector size. The emulation mitigation module may execute a first method for modifying write requests using cached data, a second method for enforcing a minimum requested data size sent to the advanced disk device, and/or a third method for conditionally retrieving data from the advanced disk device and storing to cache. In some embodiments, the second and/or third method may be used with the first method to increase the effectiveness of the first method. The emulation mitigation module may improve performance and/or data integrity for of processing legacy write requests.
