data center fundamentals

The rapid development of cloud computing in China has also brought many urgent problems. How to deploy datasets in cloud computing data centers is a hot topic for researchers. At present, there is still a lack of research at home and abroad. How to deploy datasets in various data centers is a major solution for the further development of cloud computing. A reasonable

The data center needs to "live now" In recent years, the data center market has not been very busy. Big Data Center manufacturers have targeted this cake and threw out a wide variety of products, technologies or solutions to attr

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 to have a corresponding number of basic wiring system to support, especially in the relatively centralized

For data centers, the importance of operations is self-evident, and operations management is the longest-running phase in the data center lifecycle. Data center operation is mainly to the data

What do you call a data center? Wikipedia gives the definition that "data centers are a complex set of facilities." It includes not only computer systems and other ancillary devices (such as communications and storage systems), but also redundant data communication connections, environmental control equipment, monitori

At present, IT infrastructure and its operations are increasingly complex, and people often adopt cloud computing and virtualization technology to meet a variety of business needs. Over the past 10 years, server virtualization has redeployed, managed, and optimized computing resources to transform the data center into a more flexible and efficient business application platform.
