With the deep changing healthcare system, more and more large-scale hospitals is appearing, and the large number of patients is rapidly increasing, in a way, the difficulty of management is also increased.
Some hospitals choose to conduct memory monitoring regularly or irregularly, monitoring disk space, and controlling security access, even they will check computer virus. During the time of computer running, in order not to reduce the system performance and impact the speed, they move the historical data periodically which is stored in online server to tape or CD, and properly take care of magnetic media. One computer shares disk array and one computer server stays active working status, which is called main computer. It controls disk chassis. Another computer server is standby, which is often called stand by engine. When the main computer is computer crashes, and it can’t continue providing services, the standby computer replaces the main computer in specified time. The database which is built in disk chassis can be automatically taken over by standby computer and continuous gives services to achieve non-stop working. Two-machine backup technology is able to ensure the normal operation of the system and basic operation, because it uses two servers and relates technologies that can control the crowded system. Two servers are connected by one line which is called "heart line". The "Heart line" can monitor the operation mutually. Once the standby computer which runs normally and finds that the main computer is computer crashes, it immediately takes over the "death" of the running tasks. The disk array is controlled as RAID, and it sacrifices a part of capacity to record redundant even repeated sources and ensures the reliability of disk. It avoids the situation that fail to read data because of computer crashes. It also improves the security of data and efficiency.
Different hospitals have their own methods to ensure the systems working fluently, but no matter what measures they take, they always have the same goal to achieve the improvement of running systems.
I like how they have the new stuff to improve the health care system. I can imagine how hard it can be to run a hospital. That is one business that never closes because there is always someone sick. And it can be difficult keeping up with peoples info.
