片上系统(SoC)将多个离散组件集成到单个芯片中，例如通过将CPU核心、网络接口和I/O控制器放置在同一芯片上。虽然SoC主导高端嵌入式产品已有十多年，但系统级集成是服务器领域的一种相对较新的趋势，其驱动因素是降低成本(通过减少离散部件的数量)和功耗(通过减少从内核到I/O的引脚交叉)。如今，横向扩展数据中心不断增加的成本压力需要能够降低总拥有成本(TCO)的技术。与此同时，将越来越多的可用晶体管用于更多内核和缓存的回报越来越小，这为基于SoC的服务器创造了更有力的理由。
A System-on-Chip (SoC) integrates multiple discrete components into a single chip, for example by placing CPU cores, network interfaces and I/O controllers on the same die. While SoCs have dominated high-end embedded products for over a decade, system-level integration is a relatively new trend in servers, and is driven by the opportunity to lower cost (by reducing the number of discrete parts) and power (by reducing the pin crossings from the cores to the I/O). Today, the mounting cost pressures in scale-out datacenters demand technologies that can decrease the Total Cost of Ownership (TCO). At the same time, the diminshing return of dedicating the increasing number of available transistors to more cores and caches is creating a stronger case for SoC-based servers.
