Executive Summary

Because the cloud serves many workloads concurrently, its disk access pattern is highly random and heterogeneous. In addition, because various virtual machines access to files respectively, meta data utilization and small write requests are increased. In order to build a system for these patters, the authors should analyze the modern techniques used at cloud system. First, they show that a SATA controller has enough processing capability to serve six disks without performance degradation. Motivated by this experiment, they compare three disk configurations by executing benchmark applications.
