摘要： In an embodiment, a skip read command is received that requests transfer of a requested block from a storage device and that requests non-transfer of a skipped block from the storage device. The skip read command specifies a skip mask that comprises an identification of a location of the requested block relative to a location of the skipped block at the storage device. In response to the skip read command, the requested block and the skipped block are transferred from the storage device by creating a read command that requests transfer of the requested block and the skipped block and sending the read command to the storage device. In various embodiments, the skipped block is transferred to a temporary buffer and not transferred to a destination buffer, or the skipped block is transferred to the destination buffer, but overwritten by a transfer of the requested block to the destination buffer.

摘要： A method for performing a write operation on a computer system having a main store, including a plurality of pages, and a backing store, the write operation including a processing step for processing data of the write operation and a writing step for writing the processed data to the backing store. The method includes reserving a set of pages, among the plurality of pages, in the main store, retrieving a required number of pages from the reserved set in accordance with the size of the data, processing the required number of pages of the data using the retrieved pages, writing the processed data to the backing store, and returning the retrieved pages to the reserved set upon finishing the writing.
