Design And Implementation Of Disaster Recovery Center Of Blood Information Management System

The blood center has undertaken to provide social security, adequate, effective blood and blood component products and first-class service responsibility. The information system of blood center realizes the resource sharing, information sharing, Moreover, it reduce workload, reduce human error and provide manager timely, accurate, intuitive, comprehensive information, so as to realize the.function of assistant decision. The daily business of blood center has characteristics of a large amount of information processing, data retention of a long time. Because of all reasons above, once the information system paralysis that will have the serious influence to the society and it is directly related to the safety of people’s life. So establishing a disaster recovery center of the blood information management system becomes very important.This thesis is based on a project of disaster recovery center construction in shanghai blood center. From the perspective of the construction of server cluster, storage system, configuration of software and formation of the security architecture, based on the demand, design, implementation and test as the main line, it discuss cluster system, database, middleware configuration and data replication technology based on hardware of the storage system. Through durative and concurrent pressure testing method proved that the system platform can achieve the businss application operating requirements. There are main works as follows:1. Participate in the overall architecture design of disaster recovery center. Realize the three layer architecture based on the principle of data and business centralization.2. Design and implement the software and hardware system of disaster recovery center and make the software and hardware platform of the disaster recovery center has the ability of HA and load balancing.3. Implement data replication through HP EVA Continous Access Solution. (without occupying any host resources). Ensure safety and consistency of the key data between disaster recovery center and production center.4. Create a disk backup as a copy of the original data for testing environment and proving the ability of preventing error performance through Business Copy.5. Through two times of durative pressure test, concurrent pressure test, sample data of the running state of the database and middleware system, and analysis to data.The conclusion is that the software and hardware can archive the requirements of business system running.
