The power consumption of modern datacenters is increasing rapidly. Storage in datacenter consumes much power. Today, databases, especially those for OLTP, have become a major storage application in datacenters. Therefore, power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. This paper presents a description of a novel power-saving method for large storage systems based on application I/O behavior of OLTP applications. Features of our approach are (i) measurement of actual RAID storage power consumption, (ii) analysis of I/O behavior characteristics of OLTP applications, and (iii) delayed write operation at a storage cache level based on the I/O behavior of OLTP applications. We present a measured result of power consumption of storages during an OLTP application is running, and simulations results of our power-saving methods with varying cache size of storage, which demonstrate that our method provides substantially lower storage power consumption than that of a conventional OLTP environment.
