Fishbowl Teleseminar: Economic Mechanisms for Managing Risk in Datacenters

Abstract:

To increase datacenter capability within today’s megawatt-scale power budgets, we present the case for building datacenters using processors and memories that were originally intended for mobile and embedded platforms. For web search, mobile processors are 5x more efficient than server processors. And mobile memories are 5x more efficient than those for servers. We mitigate the impact on latency and quality-of-service with heterogeneity. Mixing server and mobile hardware in a datacenter increases management complexity, however, 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 guarantees equitable hardware allocations.
