松耦合数据中心体系架构研究综述

A survey of disaggregated data center architecture

数据中心作为信息产业的基础近年来得到了飞速的发展,同时也面临着大数据时代带来的新挑战。传统数据中心架构与数据中心新兴应用特性的不匹配越发明显,同时数据中心的资源利用率也持续偏低,然而数据中心的成本和功耗却在不断走高。面对这些问题,松耦合数据中心架构的发展成为数据中心重要的发展趋势。将数据中心资源松耦合化,可以突破传统物理界限,在提高资源利用率的同时加强成本控制。本文首先总结了松耦合数据中心发展现状,然后提炼了松耦合数据中心架构的关键技术,最后对该领域未来的发展前景进行了展望。

As the foundation of the information industry,the data center has experienced rapid growth in recent years and faces new challenges brought by big data.The mismatch between the traditional data center architecture and the emerging application features of the data center is becoming more apparent.At the same time,the resource utilization of the data center continues to be low,but the cost and power consumption of the data center are constantly rising.Faced with these problems,the development of disaggregated data center architecture has become an important development trend of data center.Disaggregated data center resources can break through traditional physical boundaries,improve resource utilization,and strengthen cost control.This paper summarizes the development status of disaggregated data center architecture,and refines the key technologies of the disaggregated data center architecture,and looks forward to its future development prospects.
