The Application And Integration In ERP Of Network Storage And Disaster Recovery Integration System

With the fast development of information, computer systems have now become infrastructure in enterprises and institutions. As a result of data being essential guarantee of the existence and development of an enterprise, the safety of data and stable operation of computer system has turned out to be an important issue. Consequently, the technology of data storage and disaster recovery is developing at quite a high speed, playing an important role in actual practice of information system safety.Starting with explaining the bearing and importance of data safety, this article summarizes the development of storage technology and disaster recovery system, and elucidates in details about the concept and technical characteristic of common network storage, as well as enquiry analysis and plan and construction of disaster recovery system, especially on ERP system.The article discusses about server scheme, storage pattern, storage volume, storage structure, system extensibility, safety and software. Based on these theoretical discussions, it designed the network storage and disaster recovery technology applicable for Motic ERP system. For storage system, it adopts SAN storage pattern, adopting double FC switch, and double HBA cards in server as storage network infrastructure, and using EMC PowerPath to realize auto failure transfer, dynamic multipath load balance, path testing and auto path recovery of chain way of optical fibre. In production system, it adopts cluster technology of double server in database layer, and double host network load balance in application layer. It uses Symantec VERITAS Backup Exec as disaster recovery software, and DELL PowerValut 132T tape librarian as backup equipment. The scheme is flexible and extensible to cater for the fast increase of SAP ERP system data on the precondition of securing the safety, stability and reliability of the whole system, and saves total cost of ownership for the company.The last part of the article summarizes the scheme, and put forward requirement for further development.
