....to perform application level processing. Instead of processing low level storage protocols, these disk drives are able to execute application code, making significantly bet ter use of the storage s aggregate processing power and the interconnection network between storage devices and servers [Acharya98, Keeton98, Riedel98]. Applications can take advantage of the parallelism in large storage systems and the reduction in bandwidth possible if data is operated on at the edges of the network, before it is placed onto the expensive, shared storage interconnect. The motivation for Active Disks is illustrated in Table 1, ....

....very large SMP systems and very high bandwidth I O channels. A system with Active Disks can achieve much higher application level throughput than a system with traditional disks by offloading a significant portion of the host s work to the disks and reducing interconnect traffic. Previous work [Acharya98, Keeton98, Riedel98] has shown that similar systems can achieve performance increases across a range of applications such as data mining, image processing, and some database functions. In this paper, we focus on how Active Disks can support a real database system. We begin by explaining the modifications to a ....

....[3] 4] These studies have motivated the utility of devices with more intelligence and function. Direct network attachment of disks is being proposed to enable data transfers from devices directly to clients rather than through servers [5] 6] 7] 8] Earlier work on active disks [9] 10] [11] proposed to migrate parts of applications to storage devices resulting in filtered data. There are two main advantages of active disks. One is the parallelism available among disks. There could be more aggregate CPUpower at disks than at servers. The other is the ability to dramatically reduce ....

....sophisticated scheduling algorithms on storage devices to optimize the performance of different applications. 6RELATED WORK In response to the increasing storage and computational demand for applications such as decision support database, multimedia, the Active Disk, and IDisk models [9] 10] [11] have been proposed. These models propose to take advantage of the processing power on individual disks to run application level code. Analytical models and prototype simulators of active storage have been developed [22] An evaluation of the active disk model for decision support database is ....

....percolates up and down the hierarchy to other processors that need it. This process reduces the amount of data transfered and therefore increases the scalability of the system. The ongoing works on memories with computation capability [8, 9, 10, 11, 12, 13, 14, 15, 16, 17] and intelligent disks [18, 19, 20, 21, 22, 23, 24] provide components that could potentially be used in such a system, but our current analysis simply assumes commodity processing elements situated in proximity to the memory and disk modules. In comparison to equivalent shared memory multiprocessors, the hierarchical computing systems we studied ....

....is the list of nodes. If a list of nodes is not included, then we are referring to all the nodes in the layer. The intelligence in the different levels can be realized using intelligent memory modules investigated in recent research [8, 9, 10, 11, 12, 16, 15, 17] and intelligent or active disks [18, 19, 20, 21, 22, 23, 24]. In the near future, we expect to find storage devices in the market with 1000 MIPS cores [28] and over 4 MB of memory [29] On going effort in intelligent or active memories and disk components can thus be leveraged to implement hierarchical computing systems. If computing capability is required ....

....using clusters of commodity PCs and to large SMP systems. 9.3. 2 Intelligent Disks A group at Berkeley has estimated the benefit of Active (Intelligent in their terminology) Disks for improving the performance of large SMP systems running sort, scan, and hash join operations in a database context [Keeton98]. They estimate that decision support systems account for 35 of database server sales, and that the size of individual systems is growing by over 100 per year. Intelligent Disks are seen as a logical successor to networks or workstations, with lower cost from tighter integration and higher ....

....and 3) closer integration with on disk scheduling and optimization. Figure 1 illustrates the architecture of such a system. Previous work has shown that selective and highly parallel operations such as aggregation, selection, or selective joins can be offloaded to Active Disks or similar systems [Riedel98, Acharya98, Keeton98]. Many data mining operations including nearest neighbor search, association rules [Agrawal96] ratio and singular value decomposition [Korn98] and clustering [Zhang97, Guha98] eventually translate into a few large sequential scans of the entire data. If these selective, parallel scans can be ....
