A server is a high-performance computer that provides external services in a network environment. To provide quality services, servers need to deliver and maintain high performance for a long time using effective management. Currently, most mainstream servers run on the x86 architecture, but more people are realizing that a single architecture fails to meet today’s soaring computing requirements. With more enterprises accelerating their digital transformation, the demand for computing power is higher than ever, and this trend is generating tremendous market activity.
根据IDC的数据，在2016年计算能力的全球市场空间为9.5万台服务器，而这一数字预计将达到1420万由2023年当成千上万的高性能服务器在数据中心部署，传统的人工维护无法检测2020欧洲杯预赛及时和解决问题。因此，当务之急是为企业实现其质量基于云的服务，高效率智能运维管理。这已经影响了服务器行业，这在近几年发生了巨大的变化。高性能和低成本不再是企业唯一的担忧。相反，企业也在寻求智能高效的设备运维，以减轻运维人员的压力，降低运行成本。
在整个生命周期的服务器开始从部署，O＆M和升级管理，故障预防和诊断，智能节能和安全管理 - 华为专有智能底板管理控制器（iBMC的）起着关键的作用，确保持续，稳定的服务以较低的成本。作为用于集群和云管理的基础，所述iBMC的是一个独立的带外管理系统，该系统有助于节能和设备的O＆M中的数据中心。2020欧洲杯预赛所述iBMC的支持各种工业协议和实现基本的系统管理功能，如本地和远程诊断，远程控制台，配置管理，硬件管理，和故障诊断接口。
Starting in 2002 originally to fill the demand in the carrier industry, the Huawei server business line has expanded its scope to new, more demanding industries. In 2008, the Huawei server debuted in the Internet industry, and has provided services for enterprises worldwide since 2012. Thanks to the past 18 years' experience, Huawei has innovated a wide range of server technologies and products, including the engineering, architecture, application solution, and management software. Now let's take a deeper look at the iBMC.
- 多个远程管理工具
IBMC芯片支持服务器的部署，配置和升级使用多个远程管理工具，如基于内核的虚拟机（KVM），SOL，虚拟媒体和网络接入。更重要的是，IBMC芯片实现零接触的O＆M，解决行业突出的痛点。

IBMC芯片提供了各种各样的远程运维工具和功能，让运维人员对服务器的访问，随时随地，任何操作，如配置，升级，并报警处理。
- 主流的管理协议和software
华为iBMC的符合IPMI 1.5 / 2.0，SNMP和红鱼协议，并与主流管理软件相兼容，允许企业不同的接口集成到他们的自动化和智能化管理服务器。

The iBMC provides various user interfaces, such as the CLI, web-based user interface, IPMI integration interface, SNMP integration interface, and Redfish integration interface. All user interfaces adopt the authentication mechanism and high-security encryption algorithm to enhance access and transmission security.
- 智能故障诊断和管理
华为故障诊断与管理（FDM）是一个内部开发的一套诊断技术和工具监控硬件设备的健康状况。它默认嵌入在iBMC的和提供智能且精确的故障诊断独立于操作系统的，以确保系统的稳定性和可靠性。

The FDM supports the in-depth fault diagnosis and generates alarms for key server components, such as CPUs, DIMMs, drives, buses, and PSUs on motherboard and card. It can also predict a fault, such as system breakdown, 7 to 30 days in advance, with a fault locating accuracy of up to 93%.
除了故障自动诊断，在FDM提供了极大的各种各样的帮助运维人员在故障分析和定位功能，如击穿视频录制，屏幕录像和快照，故障报告，黑色的盒子，串口数据记录。该技术完美结合手动和智能故障诊断，帮助运维人员判断故障原因，并提供针对性的解决方案，从而避免在未来出现同样故障。
- 智能节能技术
Based on the input parameters such as the CPU load and ambient temperature, the Huawei-patented Dynamic Energy Management Technology (DEMT) intelligently adjusts the power consumption of each component in real time, helping a single server consume 15% less power without compromising its performance. The DEMT boasts three highlight technologies: frequency modulation and hibernation, Proportional Integral and Differential (PID), and Digital Thermal Sensor 2.0 (DTS 2.0).
- Frequency modulation and hibernation: adjusts the running status of core components based on service loads.
- PID: quickly adjusts the fan module speed according to the CPU temperature, reducing power consumption loss caused by misplaced adaptation.
- DTS 2.0：使用的CPU性能和温度之间的关系余量至余量范围内控制所述风扇模块的速度，降低了整个服务器的功率消耗。
- Ultimate energy efficiency in tests
华为FusionServer系列已被证明在提供权威的测试，如的SPECpower-ssj2008，设计用来测量服务器能效高的性能和极致的能源效率，特别是单位电耗的。在DEMT运行的华为FusionServer临V5系列服务器已经打破了SPEC能耗多次测试的世界纪录。
For example, in 2018, the Huawei FusionServer Pro 2288H V5 scored 13,398 to rank No. 1 in the SPECpower-ssj2008 test for 2-socket servers.

目前的数据表明，电力成本占数据中心运营成本的一半。2020欧洲杯预赛其结果是，各个行业的客户正在寻找各种方法来增加绿色的计算能力来推动他们的服务。华为是着眼于回答行业的痛点的企业。华为服务器都配备了国家的最先进的能以更低的功耗节能技术，释放超强的计算，使他们在这个数字时代必须的。
- 在三层安全保护
所述iBMC的确保了在硬件，数据和访问层管理系统的安全性。具体而言，安全是使用保护，监测和恢复安全机制增强。

The Huawei iBMC harnesses the carrier-grade firmware dual-image backup technology to improve system reliability. For example, in the event of a flash misoperation or damaged storage blocks, the system automatically switches to the backup image to ensure continuous operations. Meanwhile, an alarm is generated, indicating that the original active image changes to the standby one.
Data centers with solid device management can supercharge their everyday business operations. What are normally manual, time-consuming operations, such as device deployment and fault locating and diagnosis, are now automated, accelerated, and enhanced. Digital O&M offers near-perfect fault prediction, low power consumption, and minimized O&M costs, making it essential for any enterprise running huge data volumes. Huawei servers are fueled by the self-developed management chip and intelligent iBMC management system, and these technologies have propelled Huawei as a major player of competitive computing platforms. Looking forward, Huawei will continue to innovate and collate premium technologies designed to make intelligent, simple computing.
