Data Center Failover

Content Summary: The data disaster tolerance problem is the government, the enterprise and so on in the informationization construction process to be confronted with the important theory and the practical significance research topic. In order to realize the disaster tolerance, it is necessary to design and research the disaster-tolerant related technology, the requirement analysis of business system, the overall scheme design and system realization of disaster tolerance. 　　Based on the current situation of Xinjiang National Tax Service and the target of future disaster tolerance construction, this paper expounds the concept and technical essentials of disaster tolerance, focuses on the analysis of the business data processing of Xinjiang national tax, puts forward the concrete disaster-tolerant solution, and gives the test example. Key words: ...

In recent years, with the rapid development of information industry and the advent of the 3G era, the traffic flow has been greatly increased, all kinds of mobile multimedia services have been widely used, all kinds of mixed, diversified, personalized business data growth. There is growing pressure on the data centers that support the normal operations of the business behind them. 　　How to meet the needs of business growth has become a concern of data center construction in various industries, data center construction into a new climax. Traditional data centers have been built up to now for years, with fast-growing business developments that overload data centers, rebuilding or expanding traditional data centers ...

December 22, 2011, with the support of Industry informatization Department, Information Propulsion Division, China Data Center Industry Alliance, China IDC Industry Alliance Network undertook 2011 China Data Center construction and Operation Dimension High-level Forum opening, the Forum with "leading technology (000669, stock bar) to create the future" as the theme, The meeting will be a new generation of data center planning, construction, operation, and security and other substantive issues of extensive discussion and interactive exchanges.

Today's demand for data centers is solid and effective, and this should be done first by "reasonable use". While idle resources are a waste of money for an environment. But if you fail to make a reasonable resource allocation to the frequently used data center, it will lead to a dangerous scene. A single hardware failure may cause other physical hosts to fail. The challenge for IT managers is to use and manage computing resources across the entire environment (usually including physical, virtual, and cloud resources). This article will discuss resource planning and problem mitigation as a means to achieve the goal of resource optimization. We will also ...

Has participated in the Beijing high-end office building Network and Data center planning and implementation. During the current business, the company is responsible for building and rebuilding existing data centers. He offered to hope to pass the suit ...

A few months ago, escorts's IT team decided to consolidate data centers and virtualization, consolidating four data centers in a centralized enterprise area. As a result, there is a dedicated data center for the company's agriculture, construction, automation and road operations early in the project, and now a centralized data center in Faridabad has been able to control everything. 　　This data center consolidation saves 50% of the cost. The reason for this integration is two: one is to save the data center space, and the second is to make full use of the server. More and more servers running only one thing, maintenance, human ...

The author of Wired, Robert McMillan, has written an article in which Microsoft has spent more than $15 billion trillion to build larger network facilities to support its internet-based products, such as Bing and Skype and Windows Azure. The following is the full text of the article: in 1989, influenced by the multimedia division, and under the influence of the then senior vice President Steve Ballmer, Microsoft launched its SQL Server database ...
