| With the society and technology development, real and effective information hasbecome the most important source of corporate survival, enterprise informationtechnology has become the core competitiveness to grow. With the popularity ofenterprise information, risks and threats faced by the enterprise’s core productioninformation is also growing. The current building, including the power industry,including the widespread adoption of enterprise IT systems centralized way, moreand more centralized processing of data through a computer system at theheadquarters, forming a highly centralized business and production data has greatlyimproved automated information and data management, improve productivity andreduce labor costs. Meanwhile, the concentration of business and data also caused aconcentration risk, a variety of complicated internal and external factors andunpredictable disasters always threaten the integrity of corporate information. Sincethe data loss caused by a disaster will bring huge losses. Therefore, utilization ofvirtualization, high availability clustering, remote disaster recovery technology,information technology, design and implement a high availability of informationsystems infrastructure to ensure the safety of core business information systems,continuous and stable operation becomes an important and very urgent work.Firstly, information on the status of the domestic grid work are described,international investigation of the high availability of critical information systems andbusiness continuity standards and norms, the study of the domestic MIIT, theintroduction of the banking industry and other relevant norms and requirementsinformation on high availability grid management information systems researchindicates the overall direction; then on the international and domestic mature ITtechnologies: virtualization technology, high availability clustering technology,storage virtualization and database replication technology research and technicalanalysis carried out for the high available information grid management informationsystem design and implementation laid the theoretical foundation; papers for the nextbusiness characteristics, infrastructure, data distribution grid informationmanagement system, such as a detailed analysis of the use of personnel to adequatelyresearch the needs of the system ’s high availability, combined on the basis of thebusiness model of the current mainstream virtualization technology, such as remotedisaster recovery technology grid management information system design a highlyavailable infrastructure; then run the sample survey results with the actual gridapplications, the design of a high-availability grid information management system: aserver-based dynamic logical partitioning technology to protect the CPU, memory andother hardware resources without interrupting the application automatically migrated allocation; based high availability clustering technology to ensure the application oflocal hot standby, automatic failover occurs; based storage virtualization anddatabase replication technology for remote disaster recovery, disaster core productiondata is not lost. Finally, in order to design a blueprint, build a fake productionenvironment, to achieve a highly available network management information system,through a series of tests to verify the system’s high availability, business continuityand disaster recovery capabilities, to ensure that the system7*24safe and stable. |
