an optimal multimedia object allocation solution in transcoding-enabled wide-area storage systems
Together with the information explosion era comes the problem of high energy consumption in data centers. Among the various components of a data center, storage is one of the biggest energy consumers. Many efforts have been put on reducing energy consumptions of data centers/storage systems, from server workflow management to storage data allocation. However, most works focus on local storage systems and pay no attention to other structures of storage systems. With the exponential expanding on both the depth and width of the Internet, wide-area storage systems attract more and more attention as they are reliable, load-balancing, and easy to collaborate. In this paper, we study the energy consumption in wide-area storage systems by using multimedia objects as our special application area. We develop a multimedia object distributing algorithm based on the access pattern to multimedia objects and the topology of storage systems. We also present an in-depth analysis that provides valuable insight into the characteristics of multimedia object distribution strategies and leads to precision guarantees.
