Sichuan Unicom, A Remote Disaster Recovery System Planning And Construction

Through years of construction, operational support systems Sichuan Unicom has established a better IT system platforms, including mainframe systems, high availability clustered systems and the integration of network storage systems, but also to build a better local data backup and recovery mechanisms. Through the inspection tour operators at home and abroad mainly IT support systems for the development of the platform, the combination of business and technical Sichuan Unicom actual and future development planning, the establishment of integrated data center support, consider building a sound disaster recovery backup systems Sichuan Unicom is the next important step in the further development of.The thesis focus on Sichuan Unicorn's existing IT systems complexity of the disaster recovery environment for its performance, reliability, stability, scalability and flexibility demands are very high, and disaster recovery system must be wrong building in the normal operation of the existing system obviously caused by the impact of issues such as planning and building 4 Sichuan Unicom remote disaster recovery system issues.In the research projects in the exposition, the first study on the subject done a more meaningful in-depth discussions and prospects, the study clearly the specific content and the need to address the issue and put on the need to achieve results, based on this brief account of the related domestic and foreign advanced technologies, including EMC SRDF technology, Oracle Data Guard technology. Then it Sichuan Unicom business systems analysis and business impact analysis methodologies using a report. Then, the system will be carried out in the risk analysis and classification, and specifically to avoid or reduce the risk measures. Disaster Recovery in the choice of venue, the venue comply with the disaster assessment methods, disaster recovery centers will be chosen by China Unicom in Kehua Road engine room. The disaster recovery system in the implementation phase, the project team members in the mainframe, storage vendors engineers Blueprint through EMC's SRDF Disaster Recovery technology building of a comprehensive long-range disaster recovery system, which IBM mainframe and HP servers, storage were used EMC DMX2000 disk arrays, storage software includes Solution Enabler 5.3.1, PowerPath, etc.. After the completion of the building phase of the work, this paper, the basic objective of system testing and method. It also introduces the system after the commissioning of the exercise and maintenance management, disaster recovery system is the ability to operate successfully an important part. In this paper, the final, summed up the characteristics of the subject, done a summary of the transcript.
