Abstract:

Based on the research of the technological development and infrastructure of file storage, we present a high efficient scalable mechanism for distributed storage. Servers and storage devices that have already been used in enterprises  serve as distributed storage units and the files serve as the storage objects. We focus on establishing a distributed storage mechanism which can increase or decrease the storage units at any time with high efficiency with even zero waiting time. The more servers and storage devices a company has, the bigger role the distributed storage mechanism can play. Therefore the storage performance will be greatly enhanced, and the labor intensity of file management will be greatly reduced. More importantly, it can help enterprises make full use of the old servers and storage devices, and lessen disposable replacement investment.

Key words: high efficient scalability;distributed storage;randomized copy;zero waiting time
