Storage Appliance System Based on Content Addressable Storage

It is difficult for enterprise to build CAS (content addressable storage) appliance system because the most of CAS systems only provide API interface, to design and implement a new kind of CAS storage system is proposed in this paper. CAS interface based on http is suggested, which will turn the operation of file objects into the WEB semantic operation of URI resources, so that the management and operation of file objects can perform through a Web browser. The file object is described by the metadata model, and CAS client is established with the help of WEB server and database server, so a storage appliance system with powerful capabilities for content navigation and search can be constructed. It is easy to integrate storage appliance system with enterprise application. The CAS appliance system is extensible; the test results show that aggregate throughput of CAS appliance client will increase greatly with number of CAS server.
