Storage Power Optimizations for Client Devices and Data Centers
More InfoLess Info
Storage devices are essential to all computing systems that store user data from desktops, to notebooks and Ultrabooks to data centers. Hard disk drives (HDDs) or solid state drives (SSDs) are today's most popular storage solutions. Active power for storage devices has significant impact on the battery life of client devices. In the data center, the amount of energy required for thousands of HDDs/SSDs competes with that of small cities. This paper proposes a range of storage power optimization techniques that apply equally well to client devices and data centers.
