    摘要： A system and method for using a conventional, unmodified operating system that routinely issues disk I/O requests in a diskless network computer. An adapter receives the disk I/O requests and translates them to network I/O requests, transparently to the CPU. The requests are satisfied using the network. In this way, the operating system need not be modified to issue network calls instead of disk requests.

    摘要： A system for ensuring high reliability in a block service disk array system while promoting high performance by logically writing all changes to strides on the array while physically writing ahead to a log only a subset of the changes. Specifically, for changes of only a strip or so, the changes are written to a log, along with a commit record, and then written to disk, later deleting the changes from the log. In contrast, for relatively larger changes, i.e., for an entire (or nearly entire) stride, the old stride is not overwritten by the new, but rather is written to a new location on the disk, with the new and old locations and a commit record (but not the new stride itself) being logged and with the entries for the locations in the stride mapping table swapped with each other. In an alternate embodiment, blocks can be written to temporary locations in a RAID-1 area and lazily moved to home locations in a RAID-5 area of an array of disks.

    摘要： A mechanism is provided that aggregates data in a way that permits data to be deleted efficiently, while minimizing the overhead necessary to support bulk deletion of data. A request is received for automatic deletion of segments in a container and a waterline is determined for the container. A determination is made if at least one segment in the container falls below the waterline. Finally, in response to one segment falling below the waterline, the segment from the container is deleted. Each object has an associated creation time, initial retention value, and retention decay curve (also known as a retention curve). At any point, based on these values and the current time, the object's current retention value may be computed. The container system continually maintains a time-varying waterline: at any point, objects with a retention value below the waterline may be deleted.
