【摘要】 刀片服务器是一种HAHD(High Availability High Density,高可用高密度)服务器平台,是专门为特殊应用行业和高密度计算机环境设计的,其中每一块“刀片”实际上就是一块系统“主板”,它们可以通过“板载”硬盘启动自己的操作系统。管理员可以使用系统软件将这些母板集合成一个服务器集群,共享资源。在集群模式下,所有的母板可以连接起来提供高速的网络环境,并同时共享资源,为相同的用户群服务。在集群中插入新的“刀片”,就可以提高整体性能。而由于每块“刀片”都是热插拔的,所以,系统可以轻松地进行替换,并且将维护时间减少到最小。这些刀片服务器具有低功耗、空间小、单机售价低等特点。这些设计满足了密集计算环境对服务器性能的需求,有的还通过内置的负载均衡技术,有效地提高了服务器的稳定性和核心网络性能。刀片服务器能够最大限度地节约服务器的使用空间和费用,并为用户提供灵活、便捷的扩展升级手段。本文详细介绍了一种基于Intel公司2009年第一季度最新发行的QuickPath架构四核Nehalem-ep处理器和Tylersburg 36D、ICH10芯片组的刀片的系统和硬件设计。刀片作为下一代商用高性能服务器的主板,主要具有三个方面的功能:处理功能、接口功能以及主板管理功能。本文在介绍该刀片服务器主板的硬件设计之外,也对该主板上的高速信号的信号完整性问题做了详细分析,并且也对该主板在PCB布局布线、生产加工工艺上应注意的问题进行了详尽分析。按照论文中提出的设计方案,成功地生产出和调试通了该主板,并完成了各项性能测试,对开发下一代高性能刀片服务器具有普遍的意义。最后论文针对所设计的主板,对国内外整个刀片服务器现状做了总结和分析,并对服务器行业的发展前景作了展望。更多还原

【Abstract】 Blade server is a HAHD (High Availability High Density, high-availability high-density) server platform, designed for apecial application industry and high-density computer environments. Each piece of "blade" is actually a system mainboard, they can use the "onboard" hard disk to start their own operating system. Administrator can integrate these mainboards to a server cluster to share resource by using some system Software. In the cluster mode, all of the mainboard can be connected together to provide high-speed network environment, while sharing resources, serving for the users. We can improve the overall performance by inserting a new "blades" into the cluster. Since each "blades" are hot-plug, so the system can easily be replaced, and the maintenance time will be reduced to a minimum. These blade servers have much excellent features such as low power consumption, small space occupation, low price for each single device and so on.These design are able to meet the requirements of intensive computing environments on the server performance needs. Some can even effectively improve the stability of the server and core network performance through the built-in load balancing technology. Blade server can maximize the use of saving server space and costs, and provide users with flexible, convenient ways of extension or upgrade.This paper describes a hardware design of the blade server mainboard based on Intel Nehalem-ep quad-core processors and the Tylersburg 36D, ICH10 Chipset which will be first release at the first quarter of 2009.The board will be used for the next generation of high-performance commercial blade server mainboard and have the following three aspects functions: processing functions, interface functions and board management functions.This paper have also focused on the high-speed signal integrity on the board and what problems we should pay attention to in the PCB layout, production and processing technology in detail.We have succeeded in producing and debugging the mainboard, and completed the performance test for the board following the design in the paper. These may have universal significance for developing the next generation high-performance server board. In the end of paper, we have made a summary and analysis towards the blade mainboard which we designed and the current situation of the entire blade server at home and abroad, and and also points out the prospects for development of server industry.更多还原
