RESEARCH ON AUTOBODY PANELS DEVELOPMENTAL TECHNOLOGY BASED ON REVERSE ENGINEERING
This paper analyzed the major problem for storage part of a large database application system, such as single point of failure of disk array and high occupancy rate of disk I/O. Some common methods to solve these problems were analyzed and compared, combined with system requirements, we proposed specific a reform scheme. We realized across disk array mirroring of data by use of disk mirroring of server operating system, and then discussed the implementation process of the reform scheme. Using this reform scheme, we achieved a very good application effect: not only eliminates single point of failure of disk array, but also reduces occupancy rate of disk I/O. while CPUs occupancy rate is increased, is which completely acceptable for this system.
