Linux Ethernet Switch

A network bridge is a device that is installed on a network and does not require any subsequent configuration. The network switch is basically a multiple-port network bridge. This means that the bridge is a two-port switch. Linux can support a network bridge with multiple interfaces and become a real exchanger. Bridges are often used to improve networks that http://www.aliyun.com/zixun/aggregation/7317.html "> work poorly but cannot be rebuilt." Because the bridge is a 2-layer device (IP below the layer), ...

The White Label for a New Generation of Data Centers The term "white card" refers to a long time gone by without a brand name. ODMs (original design houses) that make white computers have also started the production of white-label switches. Making white cards look just like any other brand of switch, and the makers of those white cards are familiar to users who bought white cards, such as Accton, Celestica, Quanta, and others. Since a large number of SDN startups provide solutions that include white-label switches, white-card switches are in the ...

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 ...

The data center has never been so urgent about standards and openness as it is today. 　　In the past, we talked about data centers, more focused on energy efficiency, manageability, green energy, and other key points, looking forward to a fixed room to build a perfect and long-term effective IT infrastructure. But today is the era of cloud computing. This "Cloud" change from the architecture itself to subvert the traditional sense of it, people are again aware of the original for computing, network, storage and other resources can also be used as electricity to use them. Cloud computing brings new requirements for the data center ...

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

The Sun Fire B1600 blade system chassis Sun Fire B1600 Blade Chassis is a 16-socket 3U chassis that installs two integrated gigabit Ethernet switches, two system controllers, and two power supplies. This smart frame is highly reliable and has a server density of five times times the typical single processor 1U server. The horizontally scalable Sun Fire B1600 Blade Platform is designed for throughput calculations, allowing you to adapt to growth, more efficiently utilize computing resources, and shorten the deployment cycle ...

Cloud computing is already a very hot concept, involving a very large number of services, flexible computing services, file storage services, relational database services, key-value database services, and many others. This article will briefly explain the security issues of elastic computing services, as flexible computing is the most commonly used cloud service and also the cloud service with the highest security risk. 1. Introduction Since many things involve corporate secrets, technical details, implementation or new directions, this article does not explain. Interested can vote for a resume, we work together for cloud computing. 2....

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 ...

With the deepening of the Internet, cloud computing has a far-reaching impact on the existing IT technology, this paper focuses on the analysis of two changes. A． Cloud computing's impact on the software industry 1. A revolutionary change in the software development Model 1 The development model is transformed from stand-alone to cloud computing. The resources used by a stand-alone version of the software, is based on PC physical resources (such as PC memory and hard disk); In the era of cloud computing, this development pattern completely changed, the use of resources are no longer limited by physical resources, the use of memory can be based on the data Center Server group, the database can be through ...
