چکیده
The excellent reliability provided by RAID Level 5 data organization has been seen to be insuucient for future mass storage systems. We analyze the multi-dimensional disk array in search of the necessary improved reliability. The paper begins by introducing multi-dimensional disk array data organization schemes based on maximum distance separable error correcting codes and incorporating both strings and spares. Several gures of merit are calculated using a standard Markov failure and repair model for these organizations. Based on our results, the multi-dimensional disk array organization is an excellent approach to providing improved reliability.

Arrangement of multi-dimensional scalable video data for heterogeneous clients
A scalable video server extracts data corresponding to the resolution requested by its client from the total data containing the information encoding a full resolution video. difference between the first read position and the last read position, can be much larger than the amount of the requested data. This causes additional rotational latency in a disk and thus degrades disk performance. Furth...
متن کاملEfficient Layout Transformation for Disk-Based Multidimensional Arrays
I/O libraries such as PANDA and DRA use blocked layouts for efficient access to disk-resident multi-dimensional arrays, with the shape of the blocks being chosen to match the expected access pattern of the array. Sometimes, different applications, or different phases of the same application, have very different access patterns for an array. In such situations, an array’s blocked layout represen...

متن کاملRemove Multimedia Server Bottleneck by Network Attached Disk Array with Heterogeneous Dual Channels
Multimedia service is pervasive on the Internet now and continues to grow rapidly. Most multimedia service provider systems have adopted a typical system architecture in which the storage devices are attached privately to the server. When a client browses some multimedia data from the server, data should be fetched from the storage devices and then forwarded to the client by the server. Unfortu...
متن کاملMulti-Partition RAID: A New Method for Improving Performance of Disk Arrays under Failure
Disk arrays have been proposed as a way of improving I/O performance by using parallelism among multiple disks. This paper focuses, however, on improving the performance of disk array systems in the presence of disk failures, which are signi"cant for applications where continuous operation is of concern. Although several approaches have been explored, the goals of achieving high performance and...
