摘 要：Breakthrough device technology requires the system designer to re-think operating andapplication software design in order to realize the potential benefits of closing the access gapor pushing processing into the I/O path with coprocessors. Explore and consider how the latestmemory, compute, and interconnection devices and subsystems can affect your scalable, data-centric, high-performance cloud computing system design. Breakthroughs in device technologycan be leveraged for transition between compute-centric and the more balanced data-centriccompute architectures.The author examines storage-class memory and demonstrates how to fill the long-standingperformance gap between RAM and spinning disk storage; details the use of I/O buscoprocessors (for processing closer to data); explains how to employ InfiniBand to buildlow-cost, high performance interconnection networks; and discusses scalable storage forunstructured data.
