....flexibility. For example, the River system [2] exploits this flexibility to provide robust stream based access to large data sets. For individual accesses, dynamic set interfaces [28] can provide similar flexibility. The approaches described here may fit under such interfaces. Active disk systems [1, 15, 24] enhance storage systems with the ability to perform some application level functions. Data filtering is one of the more valuable uses of active disk capabilities, and the project database function is a column based access pattern. Thus, such a use of active disk interfaces would allow the ....

....advantage of S4 over previous versioning systems is that it has been partitioned from the operating system. While this creates another level of indirection, it adds to the survivability of the storage. S4 s device embedded storage management is another instance of many recent smart disk systems [1, 7, 15, 27, 36]. All of these exploit the increasing computation power of such devices. Some also put these devices on networks and exploit an object based interface. There is now an ANSI X3T10 (SCSI) working group looking to create a new standard for object based storage devices. The S4 interface is similar to ....

....from more expressive storage interfaces. For example, some have proposed to dynamically place data near the disk head [12, 54] or to piggyback write backs on rotational delays [4] Perhaps the clearest examples are recent proposals for object based storage [19, 18, 35] and those for Active disks [1, 41, 25]. Object based storage defines a new storage interface that is much like a file system with a flat namespace; this does make the interface somewhat more expressive, but not nearly enough in our view. Active disks would allow application code to be downloaded and executed inside disk fLrmware; this ....

....employ for their internal scheduling decisions, which are based on overall positioning overheads (seek time plus rotational latency) 49, 24] However, this may require that freeblock scheduling decisions be made by disk firmware. Fommately, the increasing processing capabilities of disk drives [1, 18, 25, 41] make advanced on drive storage management feasible [18, 54] 5.3 Applications of Free Bandwidth Freeblock scheduling is a new tool, and we expect that system designers will find many unanticipated uses for it. This section describes some of the applications we see for its use. 13 Scanning ....

....employ for their internal scheduling decisions, which are based on overall positioning overheads (seek time plus rotational latency) 51, 30] However, this may require that freeblock scheduling decisions be made by disk rmware. Fortunately, the increasing processing capabilities of disk drives [1, 22, 32, 46] make advanced on drive storage management feasible [22, 57] 2.1 Using Free Bandwidth Potential free bandwidth exists in the time gaps that would otherwise be rotational latency delays for foreground requests. Therefore, freeblock scheduling must opportunistically match these potential free ....

....in this paper. While freeblock scheduling can provide free media bandwidth, use of such bandwidth also requires some CPU, memory, and bus resources. One approach to addressing these needs is to augment disk drives with extra resources and extend disk rmware with application speci c functionality [1, 32, 46]. Potentially, such resources could turn free bandwidth into free functionality; Riedel, et al. 45] argue exactly this case for the data mining example of Section 6. Another interesting use of accurate access time predictions and layout information is eager writing, or remapping new versions of ....
