.... Bitton89, Copeland89, Hsiao90] and parity based redundancy (e.g. Muntz90, Lee91, Menon91, Holland92, Menon92, Ng92, Cao93, Hou93, Hou93a, Stodolsky93, Treiber94, Chen95] Comparisons of replication based and parity based redundancy have also relied largely upon storage subsystem models (e.g. [Patterson88, Chen91, Hou93, Hou93b, Mourad93]) and measurements of prototypes under similar workloads (e.g. Chen90a, Chervenak91] 19 Dynamic Logical to Physical Mapping Disk system performance can be improved in many environments by dynamically modifying the logical to physical mapping of data. This concept can be applied in two ways ....

....bottleneck. Several research efforts have been addressing this issue. One of them is the traditional use of large caches, both for the file system and in the disk subsystem [8, 15, 16] In addition, more recently there have been efforts to use disk arrays for improving disk subsystem performance [4, 9, 11, 13]. Most commercial systems use write through disk caches to maintain strict consistency and to allow for crash recovery. Therefore, only the read I Os get the benefit of the cache and write operations begin to dominate the traffic to the disk. It is becoming increasingly important to address the ....
