An Architecture for Private Cloud Storage System Based on Block Device

with the rapid development of the Internet, the explosive growth of the Internet-based technologies leads to a great improvement of cloud computing. And cloud storage technology is the pioneer of cloud computing technology. This paper proposes a system architecture of private cloud storage system. Private cloud storage system has some unique features compared to public cloud storage system. The private cloud storage system presented here is constituted by client, web server, administrate server, access server, location server, control server, block devices data node, logger server, authenticate server and database. In our private cloud storage system, users should access data by installing client, and managers and operators can get necessary information by accessing web server. And on the other hand, the private cloud storage system mentioned before is based on block device technology. Client is composed by a driver and a software application. And data are saved in block device data node with encrypted.
