First, the preface Cisco reports that global networking equipment is expected to increase from 5 billion units to 15 billion by 2015, and 2015 Global monthly Internet traffic will increase from 1 bytes in 2004 to 80 bytes (1 MB = 1 billion GB). In the face of such a huge internet equipment and data flow, it is bound

From June 1 onwards, China's network security work has a basic legal framework, for the network also has more legal constraints, China's information security industry into a new era. "The People's Republic of China Network security Law" further improve the personal information protection rules, in the future, the two strong competition, uncompromising embarrassing situation or can be avoided. Data

automated process engine, combined with new network optimization, will integrate invisible redundancy and Failover capabilities, which will provide more and more flexibility ,, enterprises can implement their own "N + 1" data center "edge" strategy. Considering the location, application developers are using a joint design model to build applications that are aff

of G boards and 24 ports of 40G boards with a single slot that is close to 1 TB. In the future, with the improvement of optical module technology and smaller optical modules, the 0.48 million g port density that a single slot can provide will be higher. Now, rack-mounted switches with single slot providing M ports will become popular. Due to the limited cabinet size of the data

. The head of the data center surveyed said that it was necessary to standardize beforehand to manage data center complexity. Symantec recommends that enterprises standardize on the single level of infrastructure software that supports all major applications, databases, processors and storage, and server hardware plat

Reprinted: http://www.programmer.com.cn/9767/ The concept of cloud computing originated from ultra-large Internet companies such as Google and Amazon. With the success of these companies, cloud computing, as a supporting technology, has been highly recognized and widely spread in the industry. Today, cloud computing has been widely recognized as a new stage of the IT industry development, which has been given a lot of industry and product significance. Due to its multiple meanings and complica

cabling technologies, the data center has changed from the ugly duckling to the White Swan. In a data center, if cables are randomly connected and disorderly, the data center will soon become very messy. If the layout is made thr

with single-mode fiber, because of the low active + passive integrated cost of multimode fiber, it will make multimode fiber have the absolute advantage in the application of data center, and more than 85% of the fiber cabling system in large and medium data center adopts multimode fiber. August 2009, TIA officially a

Judge whether environmental protection there are many industry can refer to the basis, at home and abroad are a lot of relevant policy support and certificati

Currently, a large number of enterprise-level computing systems use middleware to implement a wide ran

Preface The IDC room is also a long-running battle. I encountered a self-testing problem in the middle and was isolated by myself for a while. However, this just shows that my time management is poor, it seems that the direction of my future efforts has been found. When starting to knock on the data center, as said by Shi Ge, try to avoid the ready-made code used by SHI Jie, and think about the function imp

Today's data center-hosted business is becoming more and more important, and introducing effective disaster preparedness technologies is essential to effectively reduce the loss of data center failures. Data center overall disaste
