摘要
随着企业信息化建设步伐的加快,信息系统的种类和数量都在不断增加,信息系统需要进行扩容升级。目前对于信息系统应用容量与硬件容量的估算方法仍存在一定缺陷,导致信息系统估算容量与实际运行所需容量出现较大偏差,因此需要建立一套科学的信息系统容量评估模型,为企业信息化建设提供更加科学的理论依据。文章以TPC-C标准作为参考,通过基准测试模型构建典型模块容量字典与硬件设备字典,从而对信息系统的软件和硬件容量进行建模:基于信息系统实际环境,通过研究硬件设备的基准测试,建立符合实际信息系统特点的基准测试模型;依据基准测试模型,论述了典型模块容量参考字典与硬件字典的构建方法,从软件和硬件两方面对信息系统的容量进行建模,从而得到信息系统的容量模型。
With the acceleration of enterprise information construction, the types and quantities of information systems are increasing, the information system needs expansion and upgrade. There are still some defects for the estimation method of current business system application capacity and hardware resource capacity, and this will lead to the large deviation between business systems estimation capacity and actual capacity. In this regard, this paper makes a research on the capacity model modeling method based on the actual business system environment. Capacity model will provide a more scientific basis fbr the company information construction. In this paper, the TPC-C standard is used as reference, and the typical module capacity dictionary and the hardware equipment dictionary are constructed by the benchmark model. Then the capacity＇s model about the software and hardware of the infbrmation system have been constructed. According to the information system actual environment, based on the benchmark of hardware equipment, this paper establishes a benchmark test model of actual information system. Based on the benchmark test model, this paper discusses the construction method of typical module capacity reference dictionary and hardware dictionary. From the two aspects of software and hardware, the capacity of information system is modeled.
