From 2014 Huawei Cloud Computing Conference

From 2014 Huawei Cloud Computing Conference

In only three years, Huawei has turned the concept of cloud computing, big data, and technical ideas into reality and knocked on the doors of numerous industry users. At HCC 2014, this still unreliable "retreat" company once again allowed the entire industry to see Huawei as the new height in the ICT sector in the simplest way - business-driven IT.

Unchanged theme, unpretentious presentation style, irrespective of grand strategic planning, and inaudible business logic... If compared to the same level of enterprise technology summit in the IT industry, the 2014 Huawei Cloud Computing Conference (HCC 2014) is unique The style does make many media feel uncomfortable. However, in the past three years, this style did not affect the heat of the HCC conference. Every year, the number of participants attending the HCC Conference has rapidly increased. More and more companies are concerned about Huawei and are willing to join Huawei's ecosystem. This year, more than 10,000 people participated in HCC2014.

In this era of new concepts and new technologies, Huawei has also been hit by numerous question marks as soon as it enters the corporate market and targets "cloudy" emerging areas such as cloud computing and big data. However, almost every year in the HCC, Huawei's transcripts are "surprising." Looking at the results, Huawei's business revenue in 2013 was 15.2 billion yuan, with a growth rate of 32.4%. According to Gartner’s latest data, Huawei’s server shipments ranked fourth in the world in 2013, Huawei’s storage products in China Ranked No. 1 in shipments; Looking at technology, Huawei is no longer a hardware equipment supplier in cloud computing and big data, from the underlying infrastructure to cloud computing, big data system platforms, and from data centers to enterprise branches. Huawei, an individual user in the enterprise, already has the ability to provide end-to-end solutions. In the ecosystem, Huawei is an active contributor to the OpenStack community. Its number of partners in the cloud computing industry has grown at a rate of 100%. The developer community has owned thousands of companies; to see customers, Huawei's cloud computing products have been sold to more than 40 countries and regions, and are used by many customers, covering government and public utilities, telecommunications, energy, finance, transportation, and medical care. , education, media assets, manufacturing and many other industries.

When Huawei silently turned cloud computing, emerging concepts and technologies in the field of big data into reality one by one, and tapped the doors of countless industry users with it, Huawei became a company that needed to “look upwards” in the ICT field.

The myth of "joining"

For Huawei, which has been developing for more than 20 years, the best thing to do is connect. Huawei is not aiming at the corporate network market with its best-known "connection", but using "connectivity" to start a more valuable market.

In HCC 2014, Huawei released a "Global Linkage Index Report", which talks from more than 1,000 CIOs in 10 industries in 25 countries with a global economy of 78% and a population of 68%, from two dimensions. And 16 indicators for these countries to conduct a comprehensive assessment. Huawei has more scientifically, comprehensively and objectively studied the relationship between the "connection index" and economic development and national competitiveness. As a result, those countries with both economic strength and national competitiveness ranking in the top ranks are all relying on the “joint index” to gain momentum for development. Taking Germany, ranked first in the overall rankings, as an example, the index of personal and corporate connections to the Internet world is very high. The industrial Internet has increased German industrial production efficiency by 30%, and its most proud industry 4.0 revolution is also Linking all machines with the Internet in order to achieve a transformation from a manufacturing power to a big power of wisdom, all this is driven by ICT investment. In developing countries, the ranking of Chile's national joint index is also very prominent. Chile’s emphasis on ICT investment has enabled it to quickly become the center of innovation in Latin America.

The report also pointed out that for every one percentage point increase in the national connectivity index, per capita GDP will increase by 1.4% to 1.9%. More importantly, the development of developing countries is significantly larger than that of developed countries. In the Internet age, "connection" has become one of the important indicators of national competitiveness. China's joint index ranked 14th. Research on the Global Connected Index shows that 65% of companies plan to increase their investment in ICT in the next two years. Finance is the industry with the highest total number of connected index surveys in all industries. 71% of financial companies said that ICT investment growth will exceed 5% in the next two years. This is the "joining" opportunity that Huawei is best at.

As Xu Wenwei, president of Huawei Strategic Marketing stated: “The basis for streamlining IT and agile business is connectivity, and the foundation of the industry is connectivity.” Today, Huawei has helped close to one-third of the world's people achieve a close connection and communication. Based on the globalization of the "connection" experience, Huawei clearly has the ability to create the next myth.

Ability + willingness

When Huawei first made wireless products, its market share was still less than 1% of its competitors. Today, many of the “starry sky” Huawei had looked at all disappeared, and Huawei has become someone else’s “starry sky”. At HCC 2014, Zheng Yelai, president of Huawei's IT product line, used this example to tell reporters that the change in the world is driven by strength, and Huawei's strength is R&D.

Perhaps, as Zheng Ye said, Huawei is suitable for a threshold. However, technological advantages often do not necessarily translate into market advantages. The enterprise market has never lacked the case of companies whose technology is very “bovine” being eliminated. From the FusionCube all-in-one to the FusionSphere cloud operating system to the FusionInsight big data platform, cloud computing and big data products released by Huawei will soon find users and rapidly form practical applications.

When Zheng Yelai talked about Huawei's FusionCube virtualization platform, he said with confidence: “FusionCube is the industry’s No. 1 virtualization platform. No one.” In an interview after the meeting, Zheng Yelai disclosed that he was so emboldened. In addition to technical advantages, Huawei is itself the first user of FusionCube. As a cloud computing system that integrates computing, storage, networking, virtualization, and management platforms, the FusionCube all-in-one machine can quickly resolve the intricacies of the traditional data center-to-cloud transformation process. “Huawei has used its own feelings and only started to scale to the market.” Zheng Yelai said.

Huawei's big data platform, FusionInsight, had found a real user, China Merchants Bank, as early as last year. The users of China Merchants Bank stated that in the bidding process, it is not only its technical capabilities and innovative capabilities that make Huawei stand out. What is most important is that Huawei continues to invest and accumulate in these new technologies. Emerging technologies like big data are not in the hands of traditional IT vendors. Although many traditional IT vendors are also conducting big data research and investment, the determination to solve difficulties with users is not as strong as Huawei.

"To do business is to do services, and technology is only a means. Huawei is always concerned about the business demands of customers." Zheng Yelai said, "Today, the enterprise market needs a company that can move with the users to the future. It needs both A partner who has the ability and willingness to help users face challenges."

From virtualization to cloud, take a small step

Business-driven IT, this concept is hot. Huawei officially announced its entry into the cloud computing field at the end of 2010, launched the "Yanfan Plan," and officially announced the establishment of an IT product line at HCC2011 held in October of the following year. This year, the number of Huawei cloud computing products has grown by more than 40%.

At HCC 2014, Huawei officially released the FusionSphere 5.0 cloud core operating system. Huawei has enhanced its capabilities in cloud data centers and telecom clouds. "Although many domestic companies are talking about the cloud, most of them are in the stage of discussing and applying virtualization technology. In recent years, there have been some changes in the enterprise application of cloud computing." Zhang Jianhua, vice president of cloud computing product line of Huawei, told the reporter, "Cloud computing The major impact on enterprise IT is that companies are beginning to consider the possibility of business cloudization, and many users may not realize that the original business system will be migrated to a virtualization platform and all resources will be adopted with an open distributed cloud architecture. Convergence into a single resource pool improves utilization and elastic scalability, and it's difficult to achieve with virtualization alone."

Huawei has already done a series of work on how to integrate new technologies into enterprise data centers and how enterprise data centers can be transformed from cost centers to production centers. For example, at HCC 2014, Huawei's distributed Cloud Data Center (DC2) is the next-generation data center architecture with centralized management and cloud services. It is not a simple upgrade of the data center architecture, but rather a solution for companies that have the desire to embark on an IT transformation. DC2 with FusionSphere, SDN, and data center management as core technologies is an IT infrastructure that is truly created for business cloudization needs. It realizes a cloud environment that is truly managed by cloud operating systems, software-defined networks, and intelligent unified management. , allowing users to enjoy unified data center services in the most convenient way.

Currently, more than 500,000 virtual machines in more than 40 countries around the world operate on Huawei virtualization platforms. The FusionSphere cloud operating system has entered the magic four-quadrant of the Gartner x86 server virtualization infrastructure, becoming the first choice for ICT cloudization, and has been highly valued by users in the financial and media asset industries. Globally, of the more than 400 data centers that Huawei has built for its customers, 120 are cloud data centers. Huawei's pioneering distributed cloud data center DC2 has achieved breakthrough market progress and has served Xinhua News Agency, Ministry of Culture, Phoenix TV, China Telecom, and Sichuan Unicom.

In the future, cloud data centers need more computing power and faster data processing speeds. At Huawei's booth at HCC 2014, the reporter found that Huawei has initiated data center 3.0 research and innovation projects. At this stage, Huawei hopes to achieve two changes through research and innovation: first, turn the entire data center into a computer, achieve high-throughput computing, and pool all CPU, memory, and I/O resources. Second, based on the Fabric system, flexible segmentation and scheduling are achieved through software, and finally the entire data center can be upgraded by more than 1,000 times the data processing capacity of one computer.

From the "small circle" to the open and cooperative "big circle"

Huawei has been a Gold Member of OpenStack for two years. On the OpenStack website, there are real-time statistics on the contributions of all member companies and developers. Whether it is a contribution to the "larger change experience" or "Bug repair", Huawei is ranked in the top ten. Huawei ranks fourth in overall contribution to OpenStack and is the only IT company except Internet companies Google, Facebook and Yahoo.

For Huawei, the support for OpenStack is precisely an important step towards the international market. The emergence of OpenStack completely overturned the relationship between traditional vendors and customers. OpenStack is restructuring the market. As a latecomer without any burden, this is also a shortcut for Huawei to break through the existing market pattern. As Zhang Jianhua pointed out, the architecture, ideas, and interfaces of OpenStack are the most valuable things for Huawei.

Huawei's first developer forum became a major highlight of HCC2014. Huawei's openness has come up with "real money" - the open platform eSDK. This is the first comprehensive open technology support system for storage, servers, and networks. Currently, it has been opened to include network switching, wireless LTE, and data center networks. , server, storage, virtualization, video, UC, converged conferences, video surveillance, call center, BYOD, SDN, and other products and solutions. In order to better serve its partners, Huawei has also established an eSDK team to focus on supporting Huawei's ability to open products, and gradually establish a company's ability to open management mechanisms, interface specifications, open models, external presentation models, and possible future business models. Provide professional services for developers. At present, Huawei is working with more than 1,000 developers to build this open ecosystem.

Huawei leads the server and storage innovation

Business-driven infrastructure dominates IT architecture change

â–  Our reporter Guo Tao

In the past, in addition to continued efforts on SDN (Software Defined Network), Huawei had few direct responses to the "software definition" industry trend in terms of servers and storage. However, at the two-day 2014 Huawei Cloud Computing Conference (HCC 2014), Service Driven Infrastructure (SDI) became the most talked about topic. SDI, to some extent, is Huawei's “software definition”. "Strategy.

Business-driven IT innovation

Although there is still controversy about the concept of "software definition", "software definition" has been considered as the trend of the times. The key is how to make it really fall. "Software Definition" always feels somewhat abstract, and arguments such as "business definition," "application definition," and "customer-centricity," seem more grounded. Huawei has never directly indicated that it will push software-defined storage products, but has always stressed that starting from the needs of customers, product design and functionality, and other aspects to fully meet the actual needs of different customers.

According to information published by Huawei, SDI consists of software-defined storage, SDN software, and SDI hardware modules. From the perspective of IT resources, Huawei SDI embodies decoupling of hardware and software, hardware resources pooling, and computing services as the center. From the perspective of customer value, Huawei SDI embodies streamlined, efficient, and easy-to-use service innovation. According to Qiu Long, general manager of HUAWEI IT product line server, the essence of SDI is integration, that is, integration of resources and business, integration of innovation and demand.

Fan Ruiqi, president of Huawei's IT storage product line, also told reporters that in the future, no matter how the storage technology develops, “focusing on customer needs and solving customer's actual problems” is fundamental. The Huawei SDI strategy is a concrete embodiment of this core idea. In Huawei's future storage product planning, software-defined storage controllers are an important part. In terms of storage, Huawei has already had a relatively clear understanding of SDI and listed specific implementation steps: First, the integration of storage is the foundation. Its goal is to integrate various complex storage technologies and realize data. The free flow; Second, the decoupling of the data plane and the control plane on the basis of the integration of the storage architecture, which is also a key step to achieve the separation of software and hardware in the “software definition” strategy; and thirdly, by formulating a variety of strategies to achieve Fourth, better understanding of the upper application of the storage, such as what the specific workload is and how its attributes are, etc., before it can be targeted to mobilize the following storage resources to match with the upper application.

On May 15 this year, Huawei announced the OceanStor Unified Storage V3 series in Beijing. It achieves convergence in five aspects: the integration of NAS and SAN, the integration of high, medium, and low-end storage, the integration of performance and capacity, the integration of primary storage and backup, and the convergence of heterogeneous storage devices. Such extensive and in-depth integration laid the foundation for the realization of SDI. However, the software-defined storage controller has not yet been officially released. From the perspective of storage, Huawei has already prepared for the landing of SDI.

The core of SDI is "business-driven". It is not only reflected in the aspects of computing and storage, but also the core guiding ideology for implementing software-defined data centers. At the HCC2014 conference, Huawei released the SD-DC2, a business-driven cloud data center architecture. SD-DC2 will support innovations in cloud, big data, and management, helping companies build business-driven IT infrastructures with business-awareness, business intelligence, and unified management capabilities, and always maintain openness and support for heterogeneous environments.

On the server side, Huawei SDI also has a specific landing plan. It is to add an SDI card to the server (it can be a standard SDI card, can be inserted into all kinds of standardized server hardware, it can also be a software, built-in to the server In hardware, that is, adding an SDI layer between the CPU and other peripherals (including storage, network, etc.), letting the CPU concentrate on its own calculation problems, and the tasks that originally had to be shared by the CPU, such as storage and networking, are all assigned to SDI. Card to achieve. Huawei Server's SDI card can easily achieve the decoupling between hardware and software, while reducing the overall cost of ownership of the server, but also improve the flexibility of the server system. The data released by Huawei shows that compared with the traditional data center architecture, SDI can reduce the total cost of ownership by 78%.

The SDI card on the Huawei server "weakened" the CPU. Or, let the CPU focus more on the computing work that it is good at, and the other work that was originally taken care of by the CPU can be handed over to the SDI card with confidence. After Intel introduced a new generation of Xeon E5 v3 processors, although major server vendors have successively released next-generation servers using Xeon E5 v3 processors, whether they are international companies like Dell or Hewlett-Packard or Huawei, Chinese manufacturers such as Shuguang have not talked too much about the new features of Intel E5 v3 processors when releasing next-generation servers. Instead, they elaborated on how to better satisfy customer applications from the perspective of overall computing architecture innovation. Performance, improved manageability, reduced costs, increased flexibility, and more. When Huawei released a new generation of server products adopting Intel Xeon E5 v3 processors, it did not introduce the performance and functions of the servers one by one. It introduced in detail Huawei's view on future computing and how to use SDI innovation to embrace the era of cloud computing. The challenge.

Understand customer needs

At the HCC 2014 conference, Huawei released a series of the latest servers, the most notable of which is the X6800 data center server. It combines the high-density server with the entire rack delivery server, which perfectly explains the design concept of SDI. According to Qiu Long, the X6800 may replace the traditional 1U and 2U servers in the future.

The X6800 has a flexible architecture and is optimized for applications such as software-defined storage, big data, and SDI infrastructure. It is an ideal choice for cloud data center servers because it is energy-efficient, resource-efficient, convenient, reliable, and can be smoothly switched. The X6800 uses a multi-node type configuration on a single infrastructure to achieve a flexible mix of computing resources and storage resources. It supports balanced storage nodes, high-density storage nodes, and micro server expansion storage nodes. The X6800 can better support Hadoop, MPP data warehouse, big data analysis and object storage, and can save up to 50% of data center space, 30% energy consumption, and 66% of cables.

Qiu Long understands SDI in this way: SDI must integrate computing, storage, and networking. In the SDI architecture, hardware resources can be automatically pooled; SDI can also achieve application-awareness and flexible allocation of resources. "We implemented server hardware changes through SDI controllers to make software applications easier." Qiu Long said, "SDI is an innovation in server architecture that will likely change the current server market landscape and trigger A new round of server market shuffles. However, Huawei's SDI server is still just a prototype."

"We will not make so-called software-defined products in order to achieve 'software definition'." Fan Ruiqi said, "In principle, software-defined storage controllers can be embedded in storage hardware devices and can also be placed in the cloud. It can also be used as a stand-alone product, and its final product form will depend on the customer's specific needs.”

The source of Huawei's storage product innovation is customer demand. Huawei does not go it alone in its storage product innovation, but cooperates with customers to achieve joint innovation. At the HCC 2014 conference, Huawei entered into a strategic cooperation relationship with Shenzhen Broadcasting Group and Sobe Digital Technology Co., Ltd., and the first business-defined all-media cloud solution for employment in-depth cooperation helped improve the agility of customers in the field of broadcasting and television. , calmly deal with the challenges of the transition to the whole media. The cooperation between the three parties is another milestone event for Huawei to promote the innovation of the broadcasting and TV industry with IT since Huawei reached a strategic cooperation with CCTV in the field of big data storage at the HCC Conference last year. Zheng Yelai, President of Huawei's IT product line, stated: “In the face of the trend of ultra-high-definition content in the media industry and user-centric information construction, Huawei will continue to provide media industry customers with optimized large-capacity, high-performance storage and professional-grade video. Handle cloud computing platforms, lossless bearer networks, distributed data centers, and other technologies and solutions."

IT market strategist

SDI is not only a macro strategy that leads the transformation of the next-generation data center, but also a specific technical framework. Who says that Huawei does not have software-defined calculations and storage? SDI is Huawei's best interpretation of software definitions.

In many people's minds, Huawei may be the image of a "doer". Although it has been a few years since its full access to the IT market, Huawei has significantly increased sales and sales of servers and storage products, and has the ability to compete with internationally renowned manufacturers. Gartner's statistics show that in the second quarter of 2014, Huawei shipped the world's fourth-largest server shipments. In the first half of 2014, Huawei’s server shipments also ranked fourth in the world and second in China. Huawei has entered Gartner's magic four-quadrant in common disk arrays, x86 server virtualization architectures, blade servers, and integrated systems.

In the process of continuously improving the technological level and enhancing the market and sales capabilities, Huawei has become more strategic and forward-looking. Its IT business has achieved a quantum leap from qualitative change to qualitative change. The best example is the introduction of the SDI strategy. It shows that Huawei is not only a leader in product design and manufacturing, but also an innovator leading the transformation of data center infrastructure.

Huawei Announces Application-level Active-active Disaster Recovery Solution

Let the disaster recovery center "live"

â–  Our reporter Guo Tao

The system downtime incident of a bank in a certain province in northwest China not long ago gave people a wake-up call: Disaster recovery is indispensable and it is necessary to ensure continuity of business. Theoretically speaking, people understand the importance of disaster recovery. However, due to problems in capital, technology, management, and personnel, many companies have not established an effective disaster recovery system, or the disaster recovery system is in name only. When disaster recovery occurs, it cannot play its due role.

There are some shortcomings in the traditional one-by-one disaster recovery methods: disaster recovery centers are often idle and resources are not fully utilized; data in primary data centers and disaster recovery centers is difficult to ensure consistency, and enterprises are prepared for disaster recovery systems. There is no certainty that the switch will not be easily switched when a disaster occurs; there is a long delay in switching the disaster recovery system.

At the HCC 2014 conference, Huawei formally released the data center disaster recovery application-level active-active deployment and visual agile operation and maintenance management system. It efficiently activated data center resources, improved system resource utilization, and realized automatic data center service switching. , ensure zero interruption of application and zero data loss. According to Chen Shijun, general manager of Huawei's data center solution department, the release of Huawei's active-active disaster recovery solution marks Huawei's ability to provide customers with the industry's highest-level data center service continuity disaster recovery solution to meet customers' data center disaster recovery services. High reliability requirements.

At present, the industry does not have a unified definition of active living centers. Huawei defines its dual-active data center solution as two data centers that can simultaneously run services. When one data center fails, another data center can immediately take over its services to ensure zero interruption of services and zero data loss.

Su Zhongyan, technical director of disaster recovery solutions at Huawei Data Center, summarized the following features of Huawei's application-level active-active data center solution. First, the solution uses industry-leading technologies such as cloud computing, databases, and storage to implement data center storage. , database, application, network, and transmission of five levels of active-active, based on virtualization, can well support heterogeneous environments; through the balance of business load, data synchronization write technology, disaster recovery center can not only provide daily business Services, and can share the load of the production system, when a data center site fails, the other site can take over all services in real time, activate existing IT resources, achieve application-class active-active switch, further improve the resources of the disaster recovery center Utilization rate; Through the optimization of storage and network technology, this solution can reduce the time delay of data transmission, allowing customers to have more flexibility in site selection for the data center; in terms of operation and maintenance, this solution visualizes topological agile management and black box through disaster recovery. White box and other functions can provide customers with efficient, intuitive and simple overall management The tool can reduce the maintenance workload by 50% and shorten the service recovery time by 30%. Huawei also provides an innovative one-button exercise function that can save operating time, reduce the risk of manual operations, and shorten the RTO (Recovery Time Objective) by 30%. Let the disaster recovery center truly "live".

According to a survey conducted by Ponemon, a research institution, the loss caused by accidental downtime increased from 5,600 US dollars per minute in 2010 to 7,900 dollars per minute in 2014, an increase of 41%. IDC's survey results also show that more and more companies hope that the disaster recovery center can start in real time in the event of a failure. IDC recommends that enterprise users adopt the active-active data center disaster recovery solution when conditions permit.

From the current perspective, the active-active data center disaster recovery solution is the highest-level disaster recovery solution. But not every enterprise must deploy active-active data center disaster recovery solutions. This should be specifically analyzed in specific circumstances. Generally speaking, those users of industries that require very high business continuity, such as customers in industries such as finance and telecommunication, will choose the active data center disaster recovery solution. "Customers should choose different disaster recovery solutions in different businesses according to their own actual conditions." Chen Shijun analyzed that "Some large-scale Internet companies have multiple data centers scattered around each other, so cloud-based distribution can be adopted. The data center solution ensures the availability of the system.However, this cloud-based solution does not protect against natural disasters.Some enterprise users are still accustomed to centralized deployment methods, and business applications and data adopt a centralized management model. Next, the active-active data center disaster recovery solution is an ideal choice."

A good example is that the PetroChina Pipeline Bureau adopted Huawei's active-active data center disaster recovery solution in its most critical business. In the sub-critical business, it uses a traditional disaster recovery method that is both primary and secondary. The application just backs up the data. “Enterprises should divide their business and apply appropriate disaster recovery solutions according to their different needs.” Chen Shijun said, “The data center is an important strategic direction for Huawei. We are confident to help customers solve business continuity problems and make the data center more Efficient and reliable.”

Fast, green, simple

Huawei Smart DC Strengthens Three Data Center Capabilities

â–  Our reporter Guo Tao

If the problem of building a 10,000-square-meter data center can be transformed into a 100-square-meter data center as simple as that, then the construction of a data center may not be so irritating for enterprises. Micro-module data center deployment is a good way to solve the above problems. Huawei's Smart Data Center 2.0 (Smart DC 2.0) is the concept of micro-modules.

In China, the construction of data centers is a rigid demand. With the rise of cloud computing, large and even large-scale cloud data centers have mushroomed throughout the country. As we all know, the update cycle of IT equipment is 3 to 5 years, and the replacement cycle of data center infrastructure is 10 to 15 years. Therefore, during the construction of the data center, how to ensure that no over-investment, but also to meet the requirements of the sustainable development of the data center has become a problem that the current data center construction must properly solve.

The rapid development of enterprise business has put forward higher requirements for the construction speed of data centers. The traditional data center still adopts an engineering construction model, including preliminary consultation planning and design, investment cost application and approval, data center top-level design, project bidding, civil engineering, hydropower engineering, and data center computer room construction. The entire project construction cycle is not only long. , And it's complicated. “Traditional data centers have the disadvantages of long construction period, inadequate infrastructure flexibility, low overall efficiency, and high energy consumption.” Wang De, president of Huawei's data center energy sub-product line and vice president of network energy product lines, said, “In order to respond, The explosive growth of the business and the adoption of modular deployment are the general trend."

At the HCC 2014 conference, Huawei officially released the Smart DC 2.0 strategy. Its core idea is to reshape the data center with the concept of micro-modulation. The features of Huawei DC 1.0 are: PUE is less than 1.5, all components are modularized, and local visualization management is implemented. Based on this, Huawei has put forward the direction of Smart DC 2.0: PUE is further reduced by 20% on the basis of Smart DC 1.0, to achieve modular deployment of the entire computer room, and at the same time to implement refined management of the computer room.

The essence of Huawei's smart DC 2.0 is a micro-modular data center deployment. The so-called micro-module deployment is to put all the systems such as cabinets, power distribution, cooling, and supervision into one module. Each module can independently support the business and can be flexibly expanded with the development of the business. Huawei's statistics show that compared with traditional data center construction methods, micro-module deployment methods can reduce initial investment by 30%, reduce deployment time by 50%, and provide 50% of operation and maintenance personnel. Wang De thinks that the deployment of micro-modules has brought about two major changes to the construction of data centers: First, due to the adoption of micro-module design concepts, the construction of computer rooms has changed from engineering to productization, and the construction of computer rooms has become More simple, in some cases, even early planning and consulting can be omitted. Second, the room management is further intelligent. The innovative management software can monitor the running status of the module in real time, automatically find and locate the points of failure, and reduce manual management. pressure.

Huawei is not only an advocate of modular data center deployment but also an active practitioner. Huawei adopts a modular deployment approach in its own data center. In addition, Huawei is also working with telecom operators and large Internet companies to discuss the construction mode of Smart DC and hopes to formulate a set of industry standards for Smart DC. The reporter himself has visited large-scale data centers built in China using pre-built modular methods. Data centers that used to be completed in one or two years before can be built in two or three months after adopting a pre-deployed modular deployment method. The modular data center has a very good development prospect in the Chinese market.

From a product point of view, Huawei can provide end-to-end data center solutions. From a strategic perspective, Huawei vigorously develops cloud computing services. The data center is the foundation. From the perspective of data center construction theory, Huawei clearly proposes the wisdom of DC 3.0. Phased development goals will create more simple, efficient, and reliable data centers through digital, networked, and intelligent technologies.

The goal of Huawei Smart DC 3.0 is to realize modularization of the entire data center in the future, with a PUE value of less than 1.2, and at the same time achieve cloud expert management, realize predictable and proactive management in the data center, and more effectively adopt various clean energy sources. Intelligent management is the core of a new round of data center transformation. The development of Huawei's Smart DC cannot rely on Huawei alone. Huawei hopes to collaborate with and innovate with standard associations, design institutes, integrated agencies, equipment suppliers, service providers, and investment operators through an open software and hardware platform architecture to build a smart DC ecosystem.
