| With the development of power enterprise informatization,the data volume of information system is increasing,and the data security is becoming more and more important.The requirements of data reliability and security are getting higher and higher.The traditional way of disaster recovery is local backup combined with remote backup,both have their own advantages and disadvantages,the local way backups and restores fast but can not resist power outages,fires,earthquakes and other disasters,remote backup can withstand the above disaster,but the speed of backup and recovery is slow,and the disaster recovery center resources are in a long period of idle state,the above two methods are now unable to meet the new system's needs of reliability and data security,it's urgent to introduce new disaster recovery technology.This article first introduces the storage virtualization technology.Then,according to the characteristics of the data center of China Southern Power Grid's Extra High Voltage Transmission Company,the overall design of the double live data center is designed.Double live data center needs close cooperation of storage,server,network,application system,it is a complex system engineering.Based on the current situation of enterprise data center,SAN storage and Huawei VIS6600 T storage virtualization devices are selected in this paper.The implementation plan of the system is designed,the system integration is completed,and the difficulties in the implementation of the system are discussed.The storage virtualization technology and server virtualization technology,built a cross-room storage,computing resource pool.Finally,test and verify the system,including performance testing and reliability testing,prove that double live storage system across the room is a highly available information system infrastructure,can be used as an effective complement to existing disaster recovery methods to improve system reliability and data security,and to share resources between different data center. |
