Architecture Studies on Interfacing Parallel Optical Storage Systems withProcessors

摘要

Very large relational database machines require increased memory bandwidth andparallel processing to complete queries in a reasonable amount of time. Currently the machines achieve their capacity and throughput by employing an array of serial access disks and processors. As these machines grow, however, so will their need for high capacity/bandwidth storage systems. 3D parallel access storage devices have the potential of being able to achieve enormous capacity (1 Tbit/cm3)3 as well as throughput (1 Tbit/sec) and seem well suited for this application. The bit-oriented 3D two-photon memory has a further feature of being able to be accessed in a number of directions. This report examines the potential performance of a biorthogonally accessed 3D two-photon memory for relational database operations with a data organization scheme particular to this approach. The favorable results of this study lead to another study in which the feasibility of building an optoelectronic database data filter to interface with the memory was considered.
