发布时间：2018-10-15 19:46
【摘要】：随着移动通信数据量的增长，作为基础设施的服务器，其性能和系统可靠性成为了整个物理架构中的瓶颈所在。目前的解决方案是对单机进行扩容、增加CPU和内存。但是单机性能不可能无限提升；也无法解决系统单点问题，不能提高系统可靠性。 本课题以河北移动计费系统的运营分析业务升级为背景，通过对4台IBMPower750小型机进行改造升级。通过虚拟化技术提升系统的性能；利用集群技术解决了设备单点问题，，实现了业务的高可用性。本课题首先采用IBM动态Lpar的虚拟化技术针对分区高峰负载的时间不同，错峰调整不同分区的系统资源，提升系统性能；然后利用PowerHA集群原理在不同主机之间的AIX操作系统上建立集群，解决所有分区单点问题。通过上述方案的实施，本课题解决了当前服务器性能的瓶颈，消除了单点故障问题，为企业节约了成本，构建了一套高性能、高可用的集群系统，并进一步分析了中小企业IT环境中的相关解决方案和集群技术的应用前景以及发展状况。
[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.
