摘要：Recently, it has been more and more popular to build hybrid storage systems on the basis of SSD (Solid State Drives) and HDD (Hard Disk Drive). In order to evaluate the performance of various hybrid storage based algorithms, this paper proposes a flexible simulation tool called SH-Sim. SH-Sim aims to provide a flexible virtual hybrid disk which is made up of a virtual SSD and a virtual HDD. SH-Sim can run on the various types of SSDs and HDDs with different parameter configurations. SH-Sim not only simulates the hardware features of HDD and SSD, but also provides a virtual management layer for the algorithms to support the switching between algorithms. The experiment proves SH-Sim can simulate the hardware performance effectively and can support the running of various algorithms.
