The out-of-band virtualization model of network storage based on trusted computing

The technology of storage virtualization is widely used all around the world. The out-of-band network-based virtualization is an essential tendency of storage systems. According to the analysis, we find that there are some security problems in out-of-band network-based virtualization, for example the attacks to one server will do harm to the whole storage network. So we propose a secure system of storage virtualization based on trusted computing which ensures the whole storage network trusted with TPM. It introduces the risk evaluation mechanism to measure the integrity of servers. And then all the behaviors which operate storage network can be trusted. Meanwhile, it builds the trusted booting process in the virtualization controller and uses the log mechanism in servers. So the system can measure the integrity of servers through log reports.
