Research and Implementation of Survivable iSCSI Storage System

The survivability of storage systems is critical.This paper is mainly about the research and implementation of the iSCSI Based Survivable Storage System(iBSSS).A prototype system which is network-oriented centralized Storage Security System is designed and realized in this paper as well.iBSSS is a simple centralized data storage system,which offers unified management to the data of multi-user and realize the Intelligent data backup and virtual data backup for special users.Clients' data is captured by iBSSS at block-level,and version-information is added to the data which is changed at the time.The right version of data will be found to the client by version time at the virtual recovery time.
