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.
