Design and implementation of data disaster recovery system based on storage-virtualization

摘要

In this paper, we design and implement a data disaster recovery system based on storage-virtualization. The data disaster recovery system implements its function through the collaboration of multiple sites in wide-area scope. Each site is an independent data center and data disaster recovery unit. The construction of each site is based on storage-virtualization gateway which is a storage-virtualization platform supporting storage multi-protocol. Therefore, through storagevirtualization gateway's implementation of data replication, failure detection, service switch/takeover among the multiple sites, data disaster recovery could be implemented.
