Abstract: The general performance indicators of the storage product such as throughput, response time, concurrent number of I/O,and its performance under the specific applications reflect the core competitiveness. Therefore, perfor- mance testing is an important part of the storage products' development and purchase. The storage performance testing software with efficiency and high degree of confidence is the urgent need for both of the manufacturer and the customer. However,so far the usual software in the industry has some deficiencies,namely,limited scenarios,distortion of testing result, etc. Aiming at these shortcomings and current requirements, the thesis making use of autonomous component ar- chitecture (ACA) with its standardized, loosely coupled, reusable and scalable features, proposed and implemented a fca- Bible solution of a scenario simulation storage performance testing software. hhen, the technical principle of general per- formance test tools and the architecture of system were analyzed. The system model of the business simulation perform- ance test tools was presented for autonomous component architecture. The infrastructure and the component communi- cation weredesigned. The implementation principle of the main modules was proposed.
