Abstract

A cloud storage gateway is a network appliance or server which resides at the customer premises. It can integrate and translate different cloud storage APIs and increase data security. A variety of designs of cloud storage gateway have been proposed. However, existing designs cannot help users to access data stored on the cloud when cloud storage cannot be reached due to maintenance, interruptions or other failures. In this paper, we present a design of cloud storage gateway based on data dispersal. In the cloud storage gateway of our design, data is divided into redundant data blocks and parity blocks, and these blocks are stored into different cloud storage respectively. When a portion of cloud storage cannot be accessed, the new designed cloud storage gateway still able to access the required data by restoring data from other available cloud storage. Further, if an acceptable number of data blocks are lost or erroneous, the cloud storage gateway of our design can also restore the original data. And the gateway utilizes an improved LRU to improve the efficiency of cache. Experimental results show that the cloud storage gateway of our design can restore the original data when some cloud storage fail and improves the access efficiency by 20%.
