Virtual Large-Scale Disk Base on PC Grid

Abstract

With the recent flood of data, one of the major issues is the storage thereof. Although commodity HDDs are now very cheap, appliance storage systems are still relatively expensive. As a result, we developed the VLSD (Virtual Large-Scale Disk) toolkit to assist in the construction of large-scale storage using only cheap commodity hardware and software. As an experiment in using the VLSD toolkit, storage was created for an educational environment. This paper presents an evaluation of the performance of the storage by performing a GCC build on the trial production storage system both during trouble-free operation and failure.
