Redundant Arrays of IDE Drives
We report tests of redundant arrays of IDE disk drives for use in offline high energy physics data analysis. Parts costs of total systems using commodity EIDE disks are now at the $4000 per Terabyte level. Disk storage prices have now decreased to the point where they equal the cost per Terabyte of Storage Technology tape silos. The disks, however, offer far better granularity; even small insti...
متن کاملUniformly Redundant Arrays
Uniformly Redundant Arrays (URA’s) are two–dimensional binary arrays with constant sidelobes of their periodic autocorrelation function. They are widely agreed upon to be optimum mask patterns for coded aperture imaging, particularly in imaging systems with a cyclic coded mask. In this paper, a survey of all currently known construction methods for URA’s is given and the sizes and open fraction...
متن کاملTerabyte IDE RAID-5 Disk Arrays
High energy physics experiments are currently recording large amounts of data and in a few years will be recording prodigious quantities of data. New methods must be developed to handle this data and make analysis at universities possible. We examine some techniques that exploit recent developments in commodity hardware. We report on tests of redundant arrays of integrated drive electronics (ID...
متن کاملIDA-based Redundant Arrays of Inexpensive Disks
Parallel disks can improve I O performance in a man ner analogous to the use of parallel processors to im prove computation times However due to their data storage function reliability issues become exceedingly important Currently proposed schemes use shadow ing or parity to achieve reliability in parallel disks In this paper we introduce the idea of using the Informa tion Dispersal Algorithm I...
متن کاملRebuild Strategies for Redundant Disk Arrays
RAID5 performance is critical while rebuild is in progress, since in addition to the increased load to recreate lost data on demand, there is interference caused by rebuild requests. We report on simulation results, which show that processing user requests at a higher, rather than the same priority as rebuild requests, results in a lower response time for user requests, as well as reduced rebui...
