....hierarchical storage systems. We conclude in Sect. 2.6. 2.2 Previous Work on Hierarchical Storage Systems Tertiary storage is one of the system components. Efficiently using automated tertiary systems to deliver data has been discussed quite extensively in the literature. Nemoto et al. in [61] address load balancing issues among multiple tape libraries, by using a migration wagon which moves tapes among the libraries so as to relieve hot spots or drive contention. Video popularity is measured by its access frequency, while the heat (temperature) of a library is measured by the total of ....

....the system. In Sect. V we provide design examples while in Sect. VI we address the effect of non uniform video popularity. We conclude in Sect. VII. II. Previous Work Optimization of automated tertiary systems in data storage and delivery has been extensively studied previously. Nemoto et al. in [15] consider a system of multiple libraries and propose using a migration wagon to move tapes from one library to another in order to achieve load balancing. Golubchik et al. Drapeau and Katz, and Ford et al. apply the idea of RAID to library systems to improve its performance [16] 17] 18] Lau ....
