Distributed Data Center Design

With the dual drive of information technology and application, the construction, management and operation of data center are constantly being adjusted and improved. Energy efficiency and intelligent management will lead the direction of data center technology and application change. 　　The further integration of it with the data center industry will open up new horizons for the development of the data center industry. April 10, sponsored by the China Computer newspaper, "2014 China Data Center Conference" in Beijing New Century Hotel held. The Annual China Data Center Conference is the seventh session of the Year. The theme of this Congress is "energy efficiency for first management." Editor-in-Chief of China Computer News ...

Design and implementation of copy distribution algorithm for cloud data center operating system Yeming Zhangmingfujang introduces the replica distribution algorithm in cloud Data center operating system (clouds 0s), which is used to solve the problem of replica distribution in cloud storage environment, and transforms the storage node selection problem into a multiple index decision problem (MCDM), Use Topsis for solving. The algorithm can make full use of many kinds of detection data in cloud computing environment, and combine the flexible weight allocation method to adapt to most cloud storage environment. Simulation results show that the cloud 0s algorithm in the load are ...

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

The purpose of the data center is to make better use of data, data mining and data efficiency. The application of cloud computing technology in the data center is an inevitable trend. It is important to study the information security architecture of cloud computing data Center for the benefit from data center to be supported by a relatively safe and stable environment. I. Cloud computing Overview (i) cloud computing technology ranked first among the top ten most strategic technologies and trends for most organizations, Gartner, a world-renowned market research consultancy. Cloud computing refers to the delivery of IT infrastructure ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...

"Csdn Live Report" December 2014 12-14th, sponsored by the China Computer Society (CCF), CCF large data expert committee contractor, the Chinese Academy of Sciences and CSDN jointly co-organized to promote large data research, application and industrial development as the main theme of the 2014 China Data Technology Conference (big Data Marvell Conference 2014,BDTC 2014) and the second session of the CCF Grand Symposium was opened at Crowne Plaza Hotel, New Yunnan, Beijing. 2014 China large data Technology ...

"Cloud" is not only a metaphor for those networked computers, but also a computational process of data that is hidden from the server as you need it, carving out the one you need from the big cloud. It's a very romantic metaphor. Cloud computing is an emerging business computing model. Using high-speed Internet transmission capabilities, data processing is moved from personal computers or servers to computer clusters on the Internet. These computers are very common industrial standard servers, managed by a large data processing center, data centers in accordance with the needs of customers to allocate computing resources to achieve with supercomputing ...

The cloud computing concept originated in super large-scale internet companies such as Google and Amazon, and with the success of these companies, cloud computing, as its supporting technology, has been highly recognized and widely disseminated by the industry. Today, cloud computing has been widely regarded as the new phase of IT industry development, which has been endowed with a lot of industry and product level significance. Because of the multiplicity of meanings, various concepts are complex, many companies and practitioners have their own cloud, as Xu Zhimo in the "accidental" a poem said: "I am a cloud in the sky, and occasionally projected in your wave heart." Traditional ...

BEIJING, June 15, 2011--Open Data center ALLIANCE,ODCA, which is the mission of open and interoperable cloud solutions, announced important milestones in Beijing today. In just seven months, the league's membership has grown by as much as four times times, with more than 280 global IT application leaders joining the Alliance, which have accumulated more than $100 billion trillion in it budgets over the year. Open Data Center Alliance also set up a working group, with the industry's key phase ...
