Fast Reconfiguration of Data Placement in Parallel Disks

Abstract

1 Introduction The “How much information?” study produced by the school of information management and systems at the University of California at Berkeley [10], estimates that about 5 exabytes of new information was produced in 2002. It estimates that the amount of stored information doubled in the period between 1999 and 2002. It is believed that more data will be created in the next five years than in the history of the world. Clearly we live in an era of data explosion. This data explosion necessitates the use of large storage systems. Storage Area Networks (or SANs) are the leading [13] infrastructure for enterprise storage.
