基于集群服務(wù)器虛擬化技術(shù)的研究與實(shí)現(xiàn)
[Abstract]:With the increase of mobile communication data, as an infrastructure server, its performance and system reliability become the bottleneck of the whole physical architecture. The current solution is to expand the capacity of a single machine, adding CPU and memory. However, the performance of a single machine can not be improved indefinitely, nor can it solve the single point problem of the system, nor can it improve the reliability of the system. Based on the operation analysis service upgrade of Hebei Mobile billing system, this paper retrofits and upgrades four IBMPower750 minicomputers. The performance of the system is improved by virtualization technology, and the single point problem of devices is solved by cluster technology, and the high availability of business is realized. Firstly, the IBM dynamic Lpar virtualization technology is used to adjust the system resources of different partitions to improve the system performance according to the different time of peak load. Then the PowerHA cluster principle is used to set up the cluster on the AIX operating system between different hosts to solve the single point problem of all partitions. Through the implementation of the above scheme, this subject solves the bottleneck of the current server performance, eliminates the single point fault problem, saves the cost for the enterprise, and constructs a set of high performance and high availability cluster system. The application prospect and development of cluster technology in IT environment of small and medium-sized enterprises are also analyzed.
