High Continuous Availability Digital Information System Based on Stratus Fault-Tolerant Server

With the construction of harmonious society, health improvement and the rapid development of information technology, People put forward higher requirements for the hospital. Hospital information system as an online services system requires continuous operation. Server system is the key to support hospital operations. System paralyzed accident caused by Server system failure is also not uncommon. Aiming at the problem of insufficient reliability of the traditional Cluster cluster server system, The article made a in-depth technical analysis on the performance of the Stratus fault-tolerant server. Combing with the characteristics of hospital information system, it proposed the digital hospital information system structure based on Stratus fault-tolerant server and explored and analyzed the economic and technical advantages of the program. The application effect demonstrates that the program is of the economic good and can realize continuous availability.
