Write caching random data and sequential data simultaneously

摘要

A method and apparatus associated with transferring data from a remote device to a recipient device having a first memory space and a second memory space. The method includes issuing a transfer command from the remote device to request transferring a set of data to the second memory space; temporarily storing the set of data in the first memory space pending a transfer to the second memory space; and appending the set of data to other sequential data in the first memory to obtain a transfer data block of a predetermined size for transfer to the second memory space. A corresponding apparatus is provided comprising circuitry configured to buffer write commands by characterizing each write command as being either a sequential write or a random write, and responsively appending data associated with sequential write commands in order to obtain a transfer block of a predetermined size.
