Hospital Network Disaster Tolerance And Server Virtualization Design Analysis

The middle of the last century, with the rapid development of computer technology,begin to form in the hospital information system in developed countries, the UnitedStates of America, Japan etc.. The hospital information system to the70’s developedcountries with relatively mature. Hospital information construction in China in the lastcentury80’s has just started, and now has experienced more than30years, theapplication of hospital information system from the initial single user to multipledepartments independent system, and then to the LAN hospital-wide application now,the development of hospital information from the information management to thedevelopment of regional health information network system initial. At present, with thenational "golden health project" development, the construction of hospital informationenvironment has been formed, but because of the early construction of the limitedconditions, the hospital information system has now been built has been unable to meetthe growing business needs to hospitals, so the hospital information system existingshould be reformed and perfected.This paper is aiming at the above problems, the original Neijiang Chinese medicinehospital information system as the main research object, according to the actualsituation and the next few years business development needs, which is suitable for thedevelopment of hospital network disaster tolerance and server virtualization project:1.Starting from the hospital the existing situation, analyzes the existing problemsof the hospital, proposes the necessity of the transformation of the hospital.2.From three aspects of demand, software and hardware specific analysis of theexisting hospital information system, put forward the necessity of constructing thenetwork disaster tolerance.3.The mainstream of today’s disaster recovery technology platform and comparisonbetween disk array replication schemes are analyzed, based on the final design,synchronous write network disaster recovery scheme of2VERITAS StorageFoundation disk array based on image technology. 4.The storage system, system, optical fiber SAN network system, data backup andrecovery system concrete design server core network disaster recovery plan.5.Server virtualization design, main server design, storage equipment design andserver virtualization management design, the final stress test proves that the virtualserver, server virtualization design can fully meet the application of hospital actual corebusiness access...
