COMPUTER SYSTEM AND PROCESS FOR TRANSFERRING MULTIPLE HIGH BANDWIDTH STREAMS OF DATA BETWEEN MULTIPLE STORAGE UNITS AND MULTIPLE APPLICATIONS IN SCALABLE AND HIGHLY-RELIABLE MANNER

摘要

PPROBLEM TO BE SOLVED: To obtain a system that transfers multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units. PSOLUTION: The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. Redundancy information corresponding to each segment also is distributed randomly over the storage units. The redundancy information for a segment may be a copy of the segment, such that each segment is stored on at least two storage units. The redundancy information also may be based on two or more segments. This random distribution of segments of data and corresponding redundancy information improves both scalability and reliability.
