One of our infrastructure is how to solve the congestion caused by a very large amount of multimedia data. However, this issue is very closely related to the storage device of multimedia applications. Thus to overcome this issue, we must provide bandwidth based on the characteristics of HDD and SDD. The studies that rely on the data migration to enhance hybrid storage throughput don't grasp the popularity curves. They only focus on the advantages of SSDs to play up the path of the decision to move files, but not to mention when the implementation of the data migration in the system cooperation. In this paper, we present a dynamic migration mthod called IDDM (Idle-driven Data Migration) to move data between HDD and SDD. IDDM provides a virtualization platform and proposes a virtual machine scheduler to migrate data between HDD and SDD for good performance gaps without missing the real-time deadline.Compared with the previous work, our dynamic migration is more sensitive and close to the curve of the user behavior change, and enhances the SSD hit ratio to improve performance of the hybrid storage. IDDM takes advantage of the gap on the scheduler to move files dynamically in hybrid storage and change a threshold, and finally improves system throughput by up to 30%.
