This talk is part of the System Research Seminar series



To increase datacenter capability within megawatt-scale power budgets, we present the case for building datacenters using processors and memories originally designed for mobile and embedded platforms. For the Microsoft Bing search engine, mobile-class processors are 5x more efficient than server processors and we mitigate the impact on latency and service quality with heterogeneous system design. Mobile-class DRAMs are 5x more efficient than server-class parts and we identify the datacenter applications that can benefit from them. Mixing server- and mobile-class hardware in a datacenter increases management complexity, and we describe how datacenters can navigate this complexity with economic mechanisms. For performance, we present a market in which users bid for heterogeneous hardware. For fairness, we present a game-theoretic mechanism that allocates hardware equitably, guaranteeing sharing incentives, envy-freeness, and Pareto efficiency.
