Clusters have emerged as the most cost-effective solution todesign high performance and dependable data centers,which are increasingly being deployed for a wide variety of Web-based services.However, data centers contribute to a significant part of theoverall delay, which is likely to grow with the increasing useof dynamic Web contents. Furthermore, (24x7) server availabilityto host critical services appears to be a far-fetched objective. Therefore, design of high performance and dependable data centershas become a critical issue.The objective of this research is to investigate the design of a three-tierdata center consisting of a front-end Web server, a middle-tier applicationserver, and a back-end database server using the industry standard, InfiniBand Architecture (IBA) communication paradigm.A prototype data center will be implemented on a 96-nodeIBA-connected Linux cluster to investigate three research issuesusing real applications and benchmarks. The issues are quantifying the performance benefits ofusing a user-level communication technique such as IBA instead ofthe standard TCP/IP stack, proposing new performance enhancementtechniques for data centers, and characterizing the impact of differentfaults on server dependability.The research will enable effectively utilizing the IBA communication mechanismfor designing multi-tier data centers, quantifying the end-to-end performancebenefits of using IBA, developing fault-tolerant mechanisms for highly availabledata centers, and understanding the design tradeoffs between high performanceand dependability.In addition to fostering new research directions inseveral areas of data center design, the outcome of this researchis likely to have significant commercial interests.

集群已成为设计高性能和可靠数据中心的最具成本效益的解决方案，越来越多地为各种基于 Web 的服务进行部署。然而，数据中心造成了整体延迟的很大一部分，这很可能随着动态 Web 内容的使用不断增加而增长。此外，托管关键服务的（24x7）服务器可用性似乎是一个牵强的目标。因此，设计高性能、可靠的数据中心已成为一个关键问题。本研究的目的是研究由前端Web服务器、中间层应用服务器和后台服务器组成的三层数据中心的设计。使用行业标准 InfiniBand 架构 (IBA) 通信范例的终端数据库服务器。原型数据中心将在 96 节点 IBA 连接的 Linux 集群上实施，以使用实际应用程序和基准来研究三个研究问题。这些问题包括量化使用 IBA 等用户级通信技术而不是标准 TCP/IP 堆栈的性能优势，为数据中心提出新的性能增强技术，以及描述不同故障对服务器可靠性的影响。该研究将能够有效地利用IBA 通信机制，用于设计多层数据中心、量化使用 IBA 的端到端性能优势、开发高可用数据中心的容错机制，以及了解高性能和高性能之间的设计权衡可靠性。除了在数据中心设计的几个领域培育新的研究方向外，这项研究的结果可能会产生重大的商业利益。
