A study on the performance simulation model for estimating hardware scale

초록

The level of services in an information system is determined by the level of performance provided by the hardware of the system, such as the servers and the network, and the software, such as the application. Of these, the performance of the hardware is significantly affected by the specifications determined at the time of the initial implementation of the system. Therefore, when one implements a system, it should be ensured that hardware models of sufficient performance specification are selected in order to reach the targeted performance level. However, it is also apparent that high-performance hardware requires a higher investment. Therefore, from the perspective of the IT systems manager of an organization, it is important when the system is implemented to choose the hardware models that can come as close to the targeted performance level as possible within the budgetary limit. To solve this problem, organizations present instructions to calculate the appropriate scales of information system hardware. However, as these instructions are based on the capacity expected during the initial system implementation planning in the earlier stage, there are limitations in using these to establish operation plans, as deterioration in performance as the system is being operated should be anticipated. It is for this reason, in this study, that we developed an algorithm for the simulation model that can estimate the performance of the hardware not only for the initial implementation of the system but also during its operation phase. © 2014 SERSC.
