Evaluation of direct interconnect architectures for datacenters

在全球范围内，微软、谷歌和亚马逊等公司正在安装大型仓库规模的计算系统，即所谓的数据中心。 这些数据中心代表了公司的大量资本投资，并需要大量的成本和能源来维护。 随着基于Web的服务（如搜索、社交网络、游戏、银行等）的巨大增长，对构建可扩展、高性能、节能、经济高效的网络中心的基础设施的需求日益增长。 数据中心内的互连网络是一个关键的成本组成部分，并对性能产生重大影响。互连网络便于将请求传送到服务器，并提供这些请求所需的数据。本项目将探讨直接互连架构在数据中心中的应用。 这些直接互连架构在超级计算机中已被证明是成功的，并避免了许多与基于以太网的网络相关的开销，这些开销在当今的计算机中是司空见惯的。

Across the global, companies like Microsoft, Google and Amazon are installing large warehouse-scale computing systems known as datacenters. These datacenters represent a substantial capital investment by companies and require significant cost and energy to maintain. With the tremendous growth of web-based services such as search, social networking, gaming, banking, etc, there is a growing and critical need for infrastructure to build scalable, high-performance, energy-efficient, cost-effective datacenters. The interconnection network within the datacenter represents a critical cost component and has a significant impact on the performance. The interconnection network facilitates the transfer of requests to servers and supplies the data required by those requests. This project will explore the use of direct interconnect architectures for datacenters. These direct interconnect architectures have proven successful in supercomputers and avoid many of the overheads associated with Ethernet-based networks that are commonplace in today's datacenters.
