Modular data center will be the first choice for Chinese internet companies

The challenge of Internet Enterprise Data Center and the http://www.aliyun.com/zixun/aggregation/6288.html of "> Industry development Trend Characteristic

With the continuous popularization of intelligent terminals, the rapid development of various business applications, Internet enterprises are experiencing unprecedented opportunities for development. But the data center infrastructure, which is the foundation of the business, also faces great challenges. This includes the rapid expansion of the business needs of infrastructure, reduce the operational costs of infrastructure performance requirements, efficient service management of data center operations personnel and process requirements.

At present, the domestic Internet service of several major giants in the data center planning design and implementation of the deployment of the view gradually consistent. It boils down to the following several aspects.

First, the Internet Data Center will be more deployed x86 server, while the Internet Enterprise procurement deployment of server equipment configuration will be relatively uniform, and through the standard to standardize and systematize.

Second, the Internet industry data centers because of the use of multiple distributed deployment, data between the data centers to backup each other, so the single data center availability level (availability) does not need to be high; the availability level of the single data center is usually between Tier2 and Tier3.

Third, the Internet Enterprise Data Center will continue to expand the size of the single data center deployed more servers, high density, large power consumption. At the same time, with the constant updating of server development (especially the deployment of some customized servers), the power density per rack is generally upgraded from 3kw/cabinets to 7-10kw/cabinets a few years ago. With the continuous improvement of server technology and the further optimization of design, the power density of single stand in future data center will be higher. Thus, for example, a large medium data center that holds 10,000 servers, its IT load is approximately 2.5MW, and the overall power consumption of the data center will reach more than 4MW in PUE1.6 calculation. Therefore, the operation efficiency (efficiency) and efficiency optimization of data center is very important to the builders and operators of Internet Data Center.

At the same time, the timeliness of Internet business application is strong, the new business running on the line will be in a relatively short period of time to generate explosive demand for server deployment (such as the rise of Weibo, online game release, etc.). As a result, the need for Internet customers to quickly replicate their data centers to support new business deployments is beginning to emerge for rapid delivery and deployment in the datacenter.

Definition and technical features of a modular datacenter (Modular data Center, MDC)

The modular data center was first used to define the modular division (PoD) of data center sites in the design of traditional data centers (raised Floor data center), that is, dividing the entire data center site into separate areas, the size of each region, the power load, The configuration is designed according to the unified standard; the expansion of the data center extends from one module to another as business requirements increase.

The MDC was also used to describe the container data center in 2007, with the advent of the Container Data Center (containerized). Servers in the container data center are highly integrated with the infrastructure and are transported to the installation site for rapid installation and production through a standard truck (20 feet or 40 feet). The Container data center can be deployed in an open outdoor environment.

However, at present, China's domestic geographical environment determines the container deployment conditions are not available, so more and more customers began to try to use the open rack to form modular modules, the Air Supply Unit (AHU), Distribution Unit (RPP) and cabinet integration after the formation of standard modular data center module, Perform phased deployments according to business requirements. For customers, the modular data center needs the site environment is simplified as a standard plant or warehouse, do not need to carry out overhead floors and other decoration works; As long as the peripheral infrastructure (such as diesel generators, UPS and input and output distribution cabinets, refrigeration units, etc.) is completed in advance, The components within the module are scheduled in the factory, so they can be installed on the site for rapid deployment (usually 3-5 days), while the traditional data center from the planning, design, construction, until the acceptance of the operation usually takes 18-24 months.

Advantages and prospects of modular data Center application in Internet industry

In addition to the rapid deployment mentioned earlier, the characteristics of precision reproduction, the modular data center in the design and implementation of the process of the closure of the hot and cold channel, the power line and data cable path, server deployment and installation, the flow of the module within the optimal processing, so that the operational efficiency of the Modular Data Center (PUE) To maximize the optimization, in the realization of the same computing power under the premise of greatly reducing operating costs.

At the same time, the deployment of the module has not too many restrictions on the site conditions, modules can be scheduled in the factory, disassembly and transport to the customer site for rapid assembly. Modular deployment also saves the cost of laying high floors, ceilings, and wall finishes in traditional data center construction.

More and more Internet companies are starting to consider building their own data centers to provide more real-time support for business application development and infrastructure equipment optimization. The technical characteristics of the modular data center and the ease of deployment of the installation are in line with the needs and considerations of Internet customers in infrastructure to promote business development and unified operation and maintenance management, and are gradually being adopted by more and more customers to carry out relevant testing and testing.

The Dell Global Data Center Solutions team participates in the development, design and implementation of the modular data center for the country's largest internet company, the first truly commercially available modular datacenter in the country so far. The module includes 12 server racks, a total of 120KW server load power consumption, including modular framework (Base), inter-row refrigeration unit (in-row cooling), remote distribution Unit (RPP), FM200 fire control system, monitoring and access control systems, lighting systems. Other infrastructure such as diesel generators, UPS and input and output distribution, chilled water units (Chiiler) are planned and implemented by the building infrastructure Department. The IT department focuses more on the installation and application of modules and efficient servers, and does not devote too much energy and internal resources to infrastructure; future multi-module deployments are also planned and carried out. The Dell team has accumulated a set of experience in design, production, delivery, installation and testing throughout the development and implementation of the project, preparing for the wide spread of modular data centers in the Internet industry.
