Data Center Topology Design

Editor's note: Data Center 2013: Hardware refactoring and Software definition report has a big impact. We have been paying close attention to the launch of the Data Center 2014 technical Report. In a communication with the author of the report, Zhang Guangbin, a senior expert in the data center, who is currently in business, he says it will take some time to launch. Fortunately, today's big number nets, Zhangguangbin just issued a good fifth chapter, mainly introduces Facebook's data center practice, the establishment of Open Computing Project (OCP) and its main work results. Special share. The following is the text: confidentiality is the data ...

As data centers, Grid computing, supercomputing, cloud computing and other technologies and concepts rise, IT industry is also moving towards business model, technology architecture to management operations and other aspects of the direction of change. At the same time, cloud management technology has gradually entered our vision, the topic of cloud management also more and more hot. In terms of user requirements, technical features and functional composition, cloud management is mainly the management of data centers. The management focuses on the integration of key resources and business, visualization and virtualization, while Cloud management focuses on the allocation of resources on demand and the charging operation of the cloud.

Innovation and change in the past, all roads through the data center. The Enterprise data Center, as a configuration point for network, storage, and computing services, should be at the center of the mission-critical functional area because it is simple: the cost of delivering large-scale, centralized services to tens of thousands of users is so high that it can only be managed through the physical configuration of the required resources. Now all this has changed. With the growing demand for operational efficiency, sustainable business operations, dynamic business diversification, and cost competitiveness, the role of the data center is the same as it used to be ...

The test of flexibility, safety, green and reliability is in front of you. 　　This issue is an in-depth analysis of four infrastructure solutions, which are the tricks you will use to crack data center cabling problems. By examining a number of wiring enterprises for the data center to provide network infrastructure solutions, it is easy to see that in the purchase and implementation of cabling system, information managers should focus on four aspects: the design is both high-density, high reliability, high-performance and flexible characteristics, the system can be installed quickly, Does it take into account future application needs and technological developments and whether the use of the square ...

In recent years, with the rapid development of information industry and the advent of the 3G era, the traffic flow has been greatly increased, all kinds of mobile multimedia services have been widely used, all kinds of mixed, diversified, personalized business data growth. There is growing pressure on the data centers that support the normal operations of the business behind them. 　　How to meet the needs of business growth has become a concern of data center construction in various industries, data center construction into a new climax. Traditional data centers have been built up to now for years, with fast-growing business developments that overload data centers, rebuilding or expanding traditional data centers ...

Hadoop is a highly scalable, large data application that can handle dozens of TB to hundreds of PB of data through fewer than thousands of interconnected servers. This reference design realizes a single cabinet of Hadoop cluster design, if users need more than one cabinet of Hadoop cluster, can expand the design of the number of servers and network bandwidth easy to achieve expansion. Hadoop solution The features of Hadoop design Hadoop is a low-cost and highly scalable large data place ...

Open source concept is a great success in software development, so independent Industry Alliance: Open Compute Project is trying to apply the same idea to data center hardware development field. The organization is developing a set of hardware specifications and mechanical designs for motherboards, power supplies, server chassis and cabinets, and battery enclosures. This effort is expected to reduce server costs and simplify deployment for new large data centers. An industry giant is supporting this open computing project. Facebook built one of the largest data centers in the world ...

The new Generation data center is a high density, large capacity of network applications, the network bandwidth, port density, security protection and management have put forward a severe test. We see that the cloud computing data center than the traditional data center on the requirements of the network has changed a lot, which mainly includes server-server traffic into the mainstream, but also requires two-tier traffic; The increase in the number of physical servers and virtual machines within the site results in a two-tier topology; expansion, Disaster preparedness and VM migration require data Center multi-site interchange between the two tiers; Data Center multi-site selection problem by the sophomore ...

In its purest form, the switching architecture is a network topology in which nodes connect to each other by deploying multiple, effectively linked switches. This is contrary to traditional broadcast media such as Ethernet, the traditional media has only one valid path, but http://www.aliyun.com/zixun/aggregation/14477.html ">ieee and IETF and other standard agencies are improving Ethernet, Add multiple valid paths and link state routing protocols instead of spanning trees to drive data ...
