Description
Technical field
The present invention relates to a kind of method for designing of the distributed many live datas center based on cloud computing, belong to electric power information construction technique field.
Background technology
After data centralization, the business activities of enterprise more and more depend on the IT infrastructure such as data center and network, and the whole day business continuity operation of IT becomes large enterprise's IT construction and runs the target pursued with enterprise operation.Data center is the core place of computer equipment, also be the key carrying of mass data, along with the arrival of the large data age of cloud computing, the construction of data center has started new upsurge, data center is towards large-scale intensivization development, and the solution of client to data center it is also proposed higher requirement.Green energy conservation, intellectuality, automatic management are data center's development trends.
For the object that calamity is standby, enterprise generally all can build two or more data center.Primary data center bears the core business of user, and other data center mainly bears some non-key business and backs up the data, configuration, business etc. at main center simultaneously.Under normal circumstances, Each performs its own functions for main center and standby center, and when there is disaster, primary data center is delayed machine, and Backup Data center can quick-recovery data and application soon, thus alleviate the loss brought to user because of disaster.
Because disaster is small probability event, and adopt one main one for this mode, Backup Data center only just can play a role when disaster occurs, and along with the lifting of enterprise's disaster tolerance construction criteria, backup IT resource and fund can drop into increasing, mutually directly again can not be multiplexing, thus cause waste.The application of active-standby mode in addition, standby center needs longer time, relation complexity when taking over main center, often have a strong impact on the business handling of user.For overcoming above-mentioned shortcoming, many industry users such as electricity power, start focus to turn to " construction of distributed many live datas " center "; distributed many live datas center by service distribution to multiple data center; each other and behavior offering customers service; distributed live comprises two large key features more---distributed and live more, embody enterprise-class tools and when construction and usage data center, scheduling of resource utilized and the new approaches of service deployment flexibility.
Summary of the invention
