Oracle Exadata X8数据库机器白皮书说明书

Wherever Oracle Databases Live and However They Are Consumed, Exadata X8 Delivers Performance in a League of Its OwnBy Mark Peters, Principal Analyst & Practice DirectorJune 2019This ESG White Paper was commissioned by Oracleand is distributed under license from ESG.™Oracle Databases Achieve Unprecedented Speed Running on the New Exadata Database Machine X8 White PaperContentsIntroduction and Executive Summary (3)Databases: Their Market and Their Varied, Voracious Data Demands (3)The Essence of Exadata, X8, and Cloud-enhancement as Desired (5)The Bigger Truth (7)Introduction and Executive SummaryMany things in IT are talked about a lot just because they have to be, while other things are talked about very little because they cannot be. As examples: There are lengthy written guides and web communities based on myriad approaches to system integration because (let’s face it) a lot of IT over many decades has been about trying to make operational round pegs fit application square holes. On the flip side, “unique” is a word that is eschewed by pretty much everyone except for vendor marketing departments because (let’s face this, too) there’s a lot of similarity across many capabilities from much of the vendor community. The journey may vary a tad, but the destination is often similar.Oracle Exadata Database Machine has now stood for a full decade in stark contrast to both these “norms.” As an Oracle Engineered System, the need to talk about integration is essentially precluded; the same engineers who build Oracle Database also ensure the Exadata is a seamless place to run the software. Control of all the IP means Oracle has a controlled and predictable environment in which to run its Database on Exadata, which in turn means it can deliver features that bring additional business value to its customers and enable them to obtain additional operational benefits and financial payback from their Oracle Database investment.And that’s it in a nutshell: Oracle’s justifiable claim to be providing, with Exadata, the best platform for Oracle Database is derived from it having the same DNA across both elements. That commonality helps make it economically attractive, scalable, and secure. It also generates the contrast that Oracle fairly enjoys making when comparing Oracle Database running on Exadata to Oracle Database running on any other vendor’s equipment; the others are constrained to essentially treat Oracle Database like any other application sitting on a VM or running as a process on generic hardware. Exadata delivers incremental business value when combined with Oracle Database, whether in the cloud or on-premises. The arrival of Exadata X8 provides yet another positive turn of the specification—and hence, value—screw, while Exadata turning ten years old is a timely reminder to review the power of the platform in general. It’s a power borne by suitability; and to appreciate that suitability, a quick reminder of the database market and its data needs is warranted. Databases: Their Market and Their Varied, Voracious Data DemandsThe Database MarketDatabases have long served as the lifeline of crucial business applications, and thus are often a foundation of businesses. Contemporary IT—and the world as we understand it—could not function without databases. But exponential data growth, the need to support more database workloads, and the resulting database sprawl have created significant challenges for IT organizations…challenges that are now complicated and extended by the arrival of multiple iterations of the cloud. With most organizations having mandates to adopt the cloud to some extent—database workloads are no exception—they should look to a partner that can not only meet their on-premises requirements, but also provide a path to a cloud that best fits their needs. And for many, getting an identical user and operational experience would be perfect. Moreover, as much as the IT environment has changed, so have the databases themselves…such as Oracle’s latest 19c iteration. These are not the databases of past generations, and so you wouldn’t want to use obsolete approaches of the past to serve them their lifeblood (i.e., data).Database Data: Proliferation, Demands…and the CloudManaging data growth and database size are far and away the greatest challenges organizations face in their current database environments, cited by 48% of respondents in ESG research (see Figure 1).1 Other key aspects of contemporary database environments include:1 Source: ESG Survey, Enterprise Database Trends, January 2017. All ESG research references and charts in this white paper have been taken from this survey, unless otherwise noted.• Additional top challenges are database performance, supporting databases in cloud environments, and the drive for ever-better security and compliance. This is not a pick-and-mix list; users need solutions to all of these problems from their chosen vendor.• If organizations had only one database, life would certainly be easier; but ESG research shows 55% of organizations have more than 25 databases in production, and having hundreds is not at all rare (see Figure 2). These tools support everything from transactional and analytical workloads to the latest machine learning applications, and they can be running everywhere from on-premises through “cloud-adjacent” environments to the cloud.• Often databases are siloed (with their own infrastructure), which compounds the management complexity and leads to inefficient utilization of hardware and software investments.• Maintaining multiple independent environments results in complex and growing security controls/policies, access needs/rules, and patching requirements, and this only adds to the management headaches IT organizations areforced to either suffer through or try to address.Figure 1. Challenges with Database Environment and Supporting InfrastructureSource: Enterprise Strategy Group48%We do not have any challenges Lack of skilled staffCreating test/development environmentsProvisioning infrastructure on-premisesPatch, maintenance and version update processesSupporting new applications and/or usersMeeting security/compliance requirementsSupporting databases in cloud environmentsMeeting database performance requirementsManaging data growth and database sizeIn general, which of the following challenges does your organization have with its current database environment and supporting infrastructure? (Percent of respondents, N=354, three responses accepted)Figure 2. Number of Production Databases DeployedSource: Enterprise Strategy GroupThe sum of the above—complexity and database iteration combined with data growth and the need to share it across and between organizations—is driving a need for consolidation. When ESG last investigated this, 50% of organizations were already consolidating databases, with another 25% planning on it. That consolidation in turn means DBAs must merge multiple workloads onto a given infrastructure, invariably creating more performance issues to be addressed.And this is all before adding in the operational curve ball of the cloud! Database provisioning and consolidation exercises increasingly must acknowledge that the right platform can change over time. Not surprisingly, ESG’s research has found that when evaluating and selecting databases, the most important attributes are that the database be capable of being cloud-based and include the ability to easily scale up and/or down as workloads demand.2The Essence of Exadata, X8, and Cloud-enhancement as DesiredGood news comes in the shape of the “Oracle on Oracle and for Oracle” solution: Exadata. Its value proposition is a piece of cake to convey: It is an optimized platform on which to run Oracle Database. While Oracle Database can run on myriad other systems, the optimal experience is running it on Exadata. It is an Oracle Engineered System that is tuned to be best for Oracle Database and integrates unique value-add features that are unavailable from other vendors. As such, it is not general purpose, nor simply fit-for-purpose: It is purpose-built. Over its decade in the market, Exadata has grown as the—identical everywhere—foundation for on-premises, Oracle Cloud, and Oracle Autonomous Database operations. The company states that Exadata is run by 77% of the Fortune Global 100 (25% of which have also adopted Exadata Cloud Service).This paper is not designed to provide extensive technical details, but suffice it to say Exadata is an ideal database platform that combines scale-out, database-optimized compute, networking, and storage hardware (to deliver both performance and economy) with smart software in the form of both specialized algorithms that can vastly improve all aspects of 2 Source: ESG Brief, Database Purchase Criteria , June 2017.17%Less than 5 5 to 1011 to 2526 to 5051 to 7576 to 100101 to 150151 to 200More than 200Don’t know How many production databases does your organization currently have deployed? (Percent of respondents, N=354)database processing, as well as automated management to optimally handle configuration, updates, and performance.3 Better yet, all the above is true across all workloads, whether they are petabyte-scale data warehouses or business-crucial OLTP applications, and whether they are traditional business applications or next-generation analytics and machine learning. Organizations can confidently consolidate their Oracle Databases and associated workloads onto a single platform born on-premises and then extend to some, or full, public cloud consumption options if desired.With Exadata, Oracle is allowing its users to deliver against the common (but also not commonly well-defined or stable) mandate to leverage the cloud by providing paths to deploy cloud operating models ranging from optimizing on-premises infrastructure before moving to the public cloud,4 through utilizing an on-premises cloud service (Oracle Cloud at Customer) that provides a public cloud experience but with the security and control of an on-premises environment, to a Cloud Adjacent offering,5 and all the way to a public cloud deployment with Exadata Cloud Service or Autonomous Database.Exadata X8As with Exadata in general, this paper is not the place to conduct a lengthy exposition of the new Exadata X8. A few headlines serve to convey the arrival of not only dramatic specification improvements, but also some key functionality:•Speed—Scale-out servers use the improved clock-speed of the latest 24-core Intel processors, as well as NVMe flash, to help Exadata X8 deliver up to 560GB/sec I/O throughput and 6.57M OLTP read IOPS (with 3.5M IOPS at under 250 microseconds). For obvious reasons, Oracle encourages all its prospects to compare its throughput and speed with typical all-flash storage arrays.•Capacity—There are 40% higher capacity 14TB Helium disk drives (the highest capacity at which Oracle’s prerequisite availability targets can be achieved). Additionally, a new Storage Server X8-2 XT expansion unit delivers dramatically less expensive storage for less-accessed, older, or regulatory data, but with all the benefits of Oracle Database storage(e.g., Hybrid Columnar Compression,6 identical operations, and security/encryption). Think of this as seamlesslyconverging the data[base] in addition to converging the infrastructure.•Function—60% more cores in Exadata X8-2 Storage Servers help offload more Oracle Database processing and also improve security by mitigating threats such as “Spectre” and “Meltdown” in silicon, eliminating software overhead.Also, automated, cloud-scale, full-stack performance management and monitoring combines AI and years of real-world performance “triage experience” with best practices to automatically detect performance issues, proactively determine root causes, and address problems without human intervention.Exadata + Oracle Database: ‘Hand in Glove’ and Extended ValueWhile it is impressive and valuable to know about Exadata’s specifications or extensive HA features, what really sets it apart are over 60 Exadata-only features for Oracle Database, such as Fast Node and Cell Death Detection, Automatic ASM Mirror3 In patching alone, for example, organizations can use Exadata to drastically reduce the number of patches. Oracle’s website details a $200B retailer that has reduced its patches 95% p.a. This enabled its IT group to improve productivity, while allowing its DBAs to more easily ensure their infrastructure was up to date and reduce risk.4 The cloud alliance announced in June 2019 between Oracle and Microsoft further demonstrates Oracle’s determination to be a key element in the public cloud world, while acknowledging that it will play to its strengths (such as high-performance Oracle Database) and allow customers to utilize the value of other mega-clouds as appropriate.5 This offering is outlined in the ESG White Paper, The Business Advantages of Cloud Adjacent Oracle Databases on Exadata, published March 2019.6 Hybrid Columnar Compression is an approach to database data compression that utilizes both the database and storage capabilities of Exadata to significantly reduce Oracle Database capacity requirements (10-15X is the norm). Less data handled also improves performance.Reads on IO Error Corruption, Automatic Statistics, and many more. It’s a veritable smorgasbord of delights for IT operations and DBAs to use, which delivers unsurpassed—and genuine—value to Oracle Database users.Extensions to this unique hand-in-glove functionality have continued with the latest Exadata X8, most notably the machine learning that enables Automatic Indexing with Oracle Database 19c. A fully-automated capability based on technology from Oracle Autonomous Database (what Oracle refers to as a “self-driving database”), this improves database performance and eliminates manual index-tuning tasks for critical applications.7 This means that DBAs can simultaneously stop the manual task of creating indexes for applications running on Oracle Database, achieve faster performance, and gain time to focus on more strategic business objectives.Users can also use in-database machine learning without having to move any data. All the algorithms run inside Oracle Database—close to the data—which ensures no production impact. This delivers dramatic performance gains for actions such as the faster scoring and validating of models against the freshest production data.While Oracle can at times display a love for extreme detail, Exadata’s powerful core value makes that largely unnecessary. Simply, it is the most integrated, optimized, flexible, and capable place to run Oracle Databases, with a set of attributes that allow it to cost less, scale better, and be more secure than alternatives. As such, it has become a foundation for Oracle Autonomous Database and Oracle SaaS applications, and the architecturally equivalent stepping stone to Oracle Cloud. The Bigger TruthWhile the term “no brainer” is a tad simplistic and can overlook relevant adjacent factors, it is clear that unique capabilities and user-value are available with Oracle Exadata when it’s used in concert with Oracle Database. That means any Oracle Database user not utilizing Exadata is missing out on some or all of those capabilities and value.As Exadata X8 heralds the second decade for this offering, it has increased its deployment choices alongside Oracle Database to mirror the increasingly hybrid cloud world, and thus offers a congruence of architecture, features, and security wherever and however it is deployed—on-premises or in the cloud. Oracle also continues to add impressive functionality that can translate to not only IT improvements, but also business value; a prime example being the machine learning in Oracle Database 19C to enable auto indexing with Exadata X8.Oracle is not famed for being shy in its own marketing claims; regarding the use of Exadata to run Oracle Database, it likes to say that the combination is “so smart that there’s no second place.” It would be easy to dismiss that as marketing bluster, but it actually deserves consideration; “second place” would suggest vendors competing at the same level…but really Oracle has put Exadata in a league of its own.7 Oracle reports a recent test in which 15 years of manual engineering were compared with what could be done in less than 24 hours with modern machine learning when the Automatic Indexing successfully created two-thirds the number of NetSuite application indexes and also increased database and application performance.All trademark names are property of their respective companies.

1概述
网络转型是运营商发展的必由之路。
从内生原因来看,随着运营商网络流量激增、业务多样化加快,传统网络设施架构越来越无法满足业务发展的需要,业务需求的多样化与个性化要求网络更加灵活和弹性;从外部原因来看,长期以来互联网成功探索了低成本、高效率技术路线,例如开源软件、开放硬件,以及软件定义和云化架构等,这些正在冲击着运营商的网络价值和利润空间。
为应对这一挑战,中国移动提出NovoNet下一代网络发展愿景,以降低网络成本、实现业务敏捷高效。
随着运营商网络转型与重构的逐步推进,打造一个适应网络转型、满足未来电信应用需求的硬件架构平台尤为重要,从而以满足运营商愈加突显的核心网与接入网网络云化、以及新型MEC(Multi-Access Edge Computing,多接入边缘计算)的业务需求。
为此,2017年11月,中国移动联合中国电信、中国联通、中国信通院、英特尔等公司,在ODCC(Open Data Center Committee,开放数据中心委员会)共同发起了面向电信应用的开放IT基础设施项目——OTII(Open Telecom IT Infrastructure),首要目标就是形成运营商行业面向电信应用的深度定制、开放标准、统一规范的服务器技术方案及原型产品。
OTII项目得到了产业界的广泛关注,迄今为止已经得到传统电信设备、服务器、部件、固件和管理系统等领域的超过20家主流供应商的积极支持。
中国移动联合业界合作伙伴,开启了针对下一代网络业务的定制化服务器技术方案与产业生态的探索。
2技术需求及面临的挑战
运营商的机房分集团级、省级、地市、区县、接入(包括汇聚机房、综合接入机房、基站等)等众多层次,每个层次承载不同的5G及NFV网元业务。
例如核心网用户面网元多部署在地市机房;无线接入网RAN-CU功能虚拟化优先选
择在区县边缘机房;MEC业务覆盖区县、接入等各类机房。
2.1业务需求
不同的上层业务对底层硬件平台提出不同的技术需求,具体包括:
•无差别兼容上层多个VIM平台和VNF业务的需求。
硬件平台应尽量采用统一的设计和部件选型。
否则型号众多的服务器将带来大量的适配工作;•服务器性能需求。
不同网元的性能关注点有所差异,例如转发面网元对于网络带宽、转发时延和性能稳定性要求极高;
•时钟精度与同步要求。
对于部分涉及计费功能的网元应用,服务器需要具有较高的时钟精度,对于无线接入网元应用,服务器还需同时具有较高的时间同步精度;
•异构计算要求。
大量网元的虚拟化部署,如核心网和RAN CU虚拟化等,需要通过配置基于FPGA、ARM等的网卡或其它硬件加速方案卸载部分CPU功能,以节约CPU资源并提高处理效率。
2.2边缘机房环境挑战
边缘机房与核心机房相比条件较为恶劣,很多方面无法满足通用服务器的运行要求:
•机架空间有限。
传输及接入机房机架多为600mm深,部分能够达到800mm,通用服务器无法部署;
•部分机房环境温度较高。
由于制冷系统的稳定性无法有效保证,机房最高温度有时会达到45℃;
•机房空气质量欠佳;
•承重有限。
众多边缘机房并未按照数据中心标准建设;
•其它还包括抗震、供电等诸多限制。
边缘机房条件难以与大型数据中心等同,且数量庞大,所以单纯的改造机房并不现实,其中既有改造难度大造价高的原因,也有机房作为“战略资源“,很难自由扩展空间的因素,因此对服务器进行重新设计就是必经之路。
2.3运维管理需求
OTII边缘服务器承载大量电信级业务,并部署在较为恶劣的边缘机房,所以需要有强大管理运维能力保障:
•统一管理接口。
服务器需要有统一完善的管理接口要求,统一是因为多样化的管理接口将给VIM/PIM对接带来大量适配工作,完善是为了更加有效的管理服务器;
•运维高效。
边缘服务器应尽量降低对运维人员水平的要求,提高运维效率。
因此,服务器需要支持前维护,建议采用统一面板/指示灯,支持风扇热插拔等。
3解决方案
3.1配置规格及关键组件
在服务器的平台选型、主板设计、部件规格等方面,OTII项目结合运营商业务需求和面临的挑战,联合行业合作伙伴进行了一系列前期调研分析,初步技术方案如下:
在配置规格方面,核心网控制面网元对CPU、内存需求较高,同时机房环境相对较好,宜采用主流两路服务器;对于用户面网元、RAN侧网元、MEC等下沉到边缘的应用,负载以网络流量转发为主,从功耗、空间和性能需求等多方面考虑,倾向于单路低功耗方案。
例如采用英特尔至强D等SoC方案。
同时,考虑到电信业务多网络平面、网络加速和边缘异构计算等要求,也需要预留一定的扩展插槽。
在主板设计方面,对于两路CPU的配置,将采用NUMA Balance设计,以满足多PCIe设备应用环境下的性能及稳定性。
在部件规格方面,一是对网卡的性能、兼容性等有较高要求,可能需要推动
25G、100G网卡的应用以及生态的不断完善,同时加强对部件的选型要求或者形成比较严格的认证部件列表;二是对于网卡加速功能要求比较迫切,需将部分功能卸载至网卡,以提高网络处理速度并降低CPU负载,具体功能包括网络转发、IPSec、DPI和HQoS等。
3.2物理形态、供电及环境适应性
OTII边缘服务器不但需要适应边缘机房的环境,还需要满足各类边缘业务在边缘机房的交付、部署与本地运维需求。
具体包括:
•为适应边缘数据中心空间限制和机架深度,服务器深度推荐不超过470mm,最多不超过500mm;
•开关、指示灯、硬盘、线缆等采用前维护,以提高维护效率,减少对机架后方空间的要求;
•风扇能够支持热插拔,保证在线清理或更换;
•部分边缘应用场景,可能需要支持在更宽的温度范围(例如-5度~45度)内运行,并可能需要满足B级EMC、抗震等需求;
•边缘数据中心功率和承重能力有限,对服务器密度要求不高,一般计算型服务器2U高度即可,存储型服务器可进一步放宽;但考虑边缘业务未来交付方便,可能会考虑“机框+多节点”的整体设计形态。
3.3BIOS、BMC及硬件管理
OTII项目将与服务器、BMC及FW厂商合作,开发统一的针对NFV场景的服务器硬件监控、远程管理功能,使上层管理平台能够无差别的与不同供应商、不同配置规格的服务器对接。
4阶段性成果
OTII项目成立以来,三家运营商持续在内部收集、分析业务需求,合作伙伴也提供了大量技术方案建议。
经过多次的沟通讨论,已经在配置规格、核心部件选型、主板设计和硬件形态等方面达成了许多共识,多项技术研究、开发和测试
验证工作正按计划逐步推进。
在这些前期工作的基础上,现已推出首款OTII深度定制服务器参考设计原型机。
此原型机总体上反映了OTII在配置规格、硬件设计和管理维护等方面的技术要求:470mm (D) x 434mm (W) x 87mm (H)的机箱尺寸,适应边缘机房的空间、供电条件,并满足高达45摄氏度的恶劣边缘环境要求。
在配置方面也具备较强的可扩展性,以单路设计为例,原型机最多可支持18核的处理器,512G内存,具备8个2.5寸盘位,并预留3个PCIe插槽。
原型机目前已经初步具备运行能力,后续将在此基础上,进一步完善和验证软硬件兼容能力、硬件管理能力等,并将结合实际5G、MEC、ORAN等业务测试,进一步明确后续的配置规格和部件选型。
5未来行动计划
5G是运营商网络转型和新业务发展的重要契机,核心网、接入网的云化和边缘计算的兴起,都对以IT化为标志的新一代网络基础设施提出了新的要求,也创造了新的市场空间。
中国移动在全球5G引领中发挥着重要作用,从标准、技术、产业等方面多点发力,全面突破。
目前,中国移动在现网多省开展5G、MEC和NFV等应用试点,取得了不少成果与进步,当然在诸多问题上还有待进行攻关突破。
为此,OTII项目联合产业界制定了未来行动计划:
•2018年6月,推出OTII服务器原型设计方案,推动结合实际NFV、MEC等业务进一步开展测试验证、优化现有方案;
•2018年10月份,在ODCC峰会向产业界发布OTII服务器阶段性技术研究和测试成果;
•2019年,基于英特尔新一代平台和前期配置规格、部件选型和硬件管理等研究成果,正式启动OTII主板和硬件设计;
•2020年,实现OTII服务器规模应用,支撑5G业务发展。
OTII项目组希望与产业链一起,在面向电信应用的IT基础设施方面形成普遍共识与开放标准,打造能够更好满足未来电信应用需求、高效率低成本的通用硬件产品,为中国乃至全球运营商的网络转型提供范例、做出贡献。
