ABSTRACT:
In one embodiment, the present invention includes a method for maintaining a sequence of writes into a disk cache, where the writes correspond to disk write requests stored in the disk cache, and ordering cache writes from the disk cache to a disk drive according to the sequence of writes. In this way, write ordering from an operating system to a disk subsystem is maintained. Other embodiments are described and claimed.
