【摘要】：服務(wù)器(Server)是網(wǎng)絡(luò)環(huán)境中的高性能計(jì)算機(jī),它偵聽客戶機(jī)提出的服務(wù)請(qǐng)求并提供相應(yīng)的服務(wù)。服務(wù)器具有強(qiáng)大的計(jì)算、存儲(chǔ)、I/O吞吐能力。同時(shí),服務(wù)器具有高擴(kuò)展性、高可靠性、高可用性、易用性和可管理性。 目前服務(wù)器產(chǎn)品設(shè)計(jì)實(shí)現(xiàn)中出現(xiàn)的主要問題,一是計(jì)算、存儲(chǔ)、I/O性能不平衡,尤其是傳統(tǒng)的機(jī)械硬盤等存儲(chǔ)技術(shù)升級(jí)速度較為緩慢,制約著實(shí)際應(yīng)用性能的提升。二是軟件、硬件在配合方面,存在不協(xié)調(diào),硬件的資源未能被軟件充分利用,造成計(jì)算、存儲(chǔ)、I/O資源的浪費(fèi)。 本文對(duì)2U機(jī)架式雙路服務(wù)器產(chǎn)品進(jìn)行了分析,主要從四個(gè)方面開展工作：第一,先從系統(tǒng)架構(gòu)、主板、背板、轉(zhuǎn)接卡、SAS卡、Raid卡、電源、結(jié)構(gòu)、散熱設(shè)計(jì)等方面展開分析,闡述了服務(wù)器產(chǎn)品的設(shè)計(jì)實(shí)現(xiàn)過程。 第二,總結(jié)歸納了一套服務(wù)器產(chǎn)品性能評(píng)測(cè)的工具方法,并對(duì)現(xiàn)有的產(chǎn)品進(jìn)行性能評(píng)測(cè),尋找產(chǎn)品性能需改進(jìn)的地方。 第三,通過對(duì)新平臺(tái)和新部件技術(shù)的學(xué)習(xí)研究,對(duì)服務(wù)器產(chǎn)品的各個(gè)子系統(tǒng)進(jìn)行了優(yōu)化改進(jìn),從而設(shè)計(jì)實(shí)現(xiàn)了新一代的服務(wù)器產(chǎn)品。 第四,通過性能評(píng)測(cè)工具方法對(duì)上一代和新一代的產(chǎn)品進(jìn)行對(duì)比評(píng)測(cè),來驗(yàn)證設(shè)計(jì)優(yōu)化的效果,并總結(jié)形成服務(wù)器設(shè)計(jì)優(yōu)化改進(jìn)的方法,持續(xù)提高系統(tǒng)設(shè)計(jì)的能力。 最后對(duì)服務(wù)器系統(tǒng)的體系結(jié)構(gòu)、系統(tǒng)設(shè)計(jì)、部件技術(shù)、測(cè)試評(píng)估四大內(nèi)容進(jìn)行了總結(jié)歸納,對(duì)整個(gè)課題開展情況進(jìn)行了總結(jié)和展望。
[Abstract]:Server (Server) is a high performance computer in the network environment. It listens to the client's request for service and provides the corresponding service. Servers have powerful computing, storage, I / O throughput. At the same time, the server has high scalability, high reliability, high availability, ease of use and manageability. At present, the main problems in the design and implementation of server products are the unbalanced performance of computing, storage and I / O, especially the slow upgrade speed of the traditional mechanical hard disk storage technology, which restricts the improvement of practical application performance. The other is that the software and hardware are not in harmony with each other, and the resources of the hardware are not fully utilized by the software, resulting in the waste of computing, storage and I / O resources. In this paper, the product of 2U machine frame dual-channel server is analyzed, which is mainly carried out from four aspects: first, the system architecture, motherboard, backplane, transfer card, SAS card, Raid card, power supply, structure, heat dissipation design and so on. The design and realization process of server product is expounded. Secondly, this paper summarizes a set of tools for evaluating the performance of server products, and evaluates the performance of the existing products to find out where to improve the performance of the products. Thirdly, through the study of the new platform and the new component technology, the subsystems of the server product are optimized and improved, and a new generation of server product is designed and implemented. Fourthly, the performance evaluation tool is used to compare and evaluate the products of the previous generation and the new generation, to verify the effect of design optimization, and to summarize the method of optimizing and improving the design of server, so as to continuously improve the ability of system design. Finally, the system structure, system design, component technology, test and evaluation of the server system are summarized and summarized, and the development of the whole project is summarized and prospected.
