Gigabit Ethernet Network Design

Cloud computing must be at the top of the list if we are to make a selection of the hottest terms in the 2009 IT industry. It paints a blueprint of the future for all users: customers need only a laptop or a mobile phone to be able to use Web services to do what we need, even work like supercomputing. Cloud computing is an infinitely powerful computing power that provides us with unlimited space for storage and data management, as well as an infinite number of possibilities for our network usage. Such a wonderful and moving prospect, more ...

As cloud computing applications grow, more and more users are starting to deploy their million-gigabit networks. In order to help enterprises design, purchase private cloud, public http://www.aliyun.com/zixun/aggregation/13647.html "> Cloud data center structure, Lippis The Ixia Ethernet Data Center Switch Industry assessment was conducted by the FORCE10 and IP network test solution provider, and Dell's S4810 Gigabit switch performed well in the tests. D ...

In today's society, information has become a very critical resource, it must be transmitted accurately and rapidly among various communication devices, data processing equipment and display devices. 　　For this reason, companies, businesses, and government departments will require the fastest speed to adjust and improve these communications and information systems, and to configure them to different structures as needed. In China, even in some newly designed buildings, often still use the past those wiring technology, resulting in a variety of systems cabling is incompatible, difficult to adapt to the development of new technologies, and pipeline congestion, and the distribution of investment is often ...

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 ...

In this article, we will introduce users in the data center cabling project encountered 10 problems and Wu, Zhang Yi and Chen Yutung and other experts to answer. 　　1. Q: On the construction of cable across long distance I encountered this situation in the unit, the office building is too wide, and the Internet access point in the most left of the building, to achieve every floor has Internet access, but also fast, how to solve? Chen Yutung: The balance twisted pair is 100 meters in support of data application, which is defined by international standards. In more than 100 meters of ...

Although every part of modern data centers is critical, the network is the Absolute foundation of all communications. That's why it's necessary to design and build a reasonable network from the start. After all, without a solid network, even the best servers and storage can do nothing. To this end, we provide several design points and best practices to help you consolidate this communication base. Consideration of the network core the word "network" can be applied to multiple domains from LAN to San, WAN. All of these areas require a network core. Our discussion starts here ...

With the rise of new businesses such as cloud computing, mobile Internet and Web2.0, traditional data centers have been unable to meet. The industry is setting off a new wave of data center construction, with the next generation of cloud computing data centers. Network is one of the important components of cloud data center, the network Architecture of cloud data center must have five new technology features: 100G Ethernet technology, surge cache, network virtualization, unified Exchange, green energy-saving technology. 100G Ethernet Technology Bandwidth pressure is the core problem of cloud data center network. In the data center, like video-on-demand, 10G FCoE ...

The "massive data" attack is impacting the traditional network architecture, the need for greater bandwidth, higher speeds, and more capacity drives the network architecture to change, especially with the deployment of cloud computing scale, and how data centers respond to and adapt to the new network environment as new research topics. With the rapid development of mobile Internet, the popularity of intelligent terminals, as well as social networks, video entertainment and other emerging business forms of more and more rich, so that the data flow exponentially climb. Expanding the size of the data center and strengthening the capacity of business is beyond doubt. Bo Tong Company's infrastructure and network division products market ...

With the development of network, database and related application technology, especially the wide application of Internet and Intranet, the world is entering the era of Network Center computing (receptacle centric Computing). 　　The logistics industry has also developed from the traditional material information movement to provide low-cost services for consumers using information technology. The definition of logistics informatization is: the use of information technology to integrate the internal business processes, so that enterprises to scale management, network operation direction. Sth.

There are more articles on the Hadoop reference Design group components and critical steps, so the small set of Hadoop reference Design group components and key steps are divided into sections to give you a detailed introduction. Software operating system: Hadoop supports any operating system that can run the Java environment. In practical applications, the average customer will choose the 64-bit versions of different Linux distributions. In this reference design we chose the free enterprise-class Linux CentOS6.3 x64 version. Hadoop system: Hadoop is based on ...
