....disk drives are frequently the most critical I O components, since disk performance is limited by mechanical delays. In order to reduce disk I O overheads, several techniques and optimizations have been proposed. This literature includes work on optimizing the scheduling of disk requests [33, 3, 17, 15], disk arrays [10, 4, 34] and optimizing disk writes using logs [23, 13, 32] Despite these techniques and optimizations, low disk throughput is still a serious problem for data intensive servers, such as Web proxies, email and news servers, multimedia servers, and database servers. An important ....
....[16, 30, 11] have been proposed for segment based caches. None of these works considered host guided caching or block based cache organizations. A few other papers discuss techniques for disk controllers. These papers include works on the scheduling of disk requests [33] utilizing free bandwidth [17], the replication of disk data [34] and disk arrays [10, 34, 4] These techniques reduce seek and or rotational overheads through sophisticated request scheduling or by accessing the closest copy of a block. Our techniques are orthogonal to these contributions. In particular, FOR reduces the ....

....read locality and the cost of segment cleaning (or disk garbage collection) 13, 14] PersonalRAID mainly targets personal computing workloads, which are often bursty and leave ample idle time for cleaning. The cleaning overhead can be further reduced by using techniques like freeblock scheduling [7], and by buying bigger disks and keeping the disk utilization low. The base LLD design that we have borrowed has several potential disadvantages [1] Keeping the entire logical to physical map in memory, the base LLD design consumes a large amount of memory and incurs some latency when reading ....
