An Auxiliary Storage Subsystem to Distributed Computing Systems for External Storage Service

摘要

Demands for efficient and effective utilization of computing resources have derived distributed computing systems of the large scaled such as Grid for scientific computing and Cloud for utility computing. In these distributed computing systems the total capacity of consolidated storages should expand as the amount of user data grows. The user's data are necessarily kept in the distributed computing system such as the Grid and the Cloud, which some users don't allow the system to. In this work, an auxiliary storage subsystem is proposed to provide external storages to the distributed computing system. The storage subsystem lets the iSCSI devices be connected to the distributed computing system as needed. As iSCSI is a recent, standard, and widely deployed protocol for storage networking, the subsystem is able to accommodate many types of storages outside of the distributed computing system. The proposed subsystem could transmit data by streams attaining high bit rate of the network capacity in the experiment.
