Exchange Server High Availability

Can you imagine the consequences of a patient's medical information system interruption in the course of medical treatment? Stable system, efficient service in the medical profession is particularly important in addition to the timely release of patient pain, and even return to life. Whether in the registration, medical treatment, hospitalization, fees and other processes, any point of the system failure will trigger a ripple effect. In a critical business system that requires continuous operation, the business stop caused by failures such as server downtime will result in immeasurable loss. In the form of the new medical reform, the information process of healthcare industry is advancing rapidly, more and more hospitals are speeding up ...

First, the customer background Zhejiang Province Education Examination Institute, mainly undertakes the province's national education examination and the enrollment work laws and regulations, the principle policy, formulates and organizes the province to carry out the education examination, the enrollment work concrete measure and the method; 　　College enrollment and other work. Second, the customer faces the challenge with the continuous expansion of the business scale of Zhejiang Education Examination College, we need to build a large number of business systems, undertake a large number of data computing work, traditional decentralized rack server and ...

The era of universal computing has come! If we had seen this slogan 10 years ago, our first reaction was that every family had at least one computer that became a computing terminal. 　　However, today, more and more computing equipment around us, mobile phones, tablets, etc. gradually began to replace the computer as a new small partner, and these devices are more frequent interaction. At present, almost all terminal devices are able to access the Internet, the resources can be obtained after the network is almost endless, equipment out of the Internet will appear to be eclipsed, the availability of significantly reduced. Complex and complicated terminal equipment need network ...

With the rapid development of mobile data, cloud computing and big data services, the scale of data center construction is getting larger and larger. Data center owners' demands for energy conservation in data centers also gradually come to the fore. In recent years, many data center energy-saving technologies have emerged, but none of them has broken through the bottleneck of thinking. They have been paying attention to the technical innovation of data center infrastructure at their own level without incorporating the server facilities into data center energy conservation projects. In a unified manner, Think about energy-efficiency issues in your data center, making it hard to break the 1.60 threshold of data center design PUE. Dawn liquid-cooled server P ...

1. Open architecture vs Closed environment Open architecture server platform and closed platform The essential difference is not whether the software is open source or not. What we are talking about here is the openness and closure of the underlying infrastructure. Unlike the traditional RISC minicomputer closed environment, the closed environment in cloud computing is more specific to the solution, the relative closure of each part of the data center. The open architecture, on the other hand, is the x86 architecture server that is at its zenith, and its open ecological environment is widely recognised. So, for cloud computing and ...

In the Desktop cloud computing solution, the server plays an important role, carrying all the user data, applications, and computing tasks, in other words, the server is related to the performance of the entire Desktop cloud computing architecture. So, in the server selection, which kind of server is more suitable for desktop cloud computing infrastructure construction? 　　Blade server is an ideal solution, its high-density, centralized management, easy to expand, easy to manage features such as desktop cloud computing applications are very compatible with the implementation of more efficient virtualization, hosting desktop cloud computing applications. Higher computational density: blade is a more ...

Computing the number of cluster projects in Linux is like counting the number of startups in Silicon Valley. Unlike Windows NT, which is already hampered by its own closed environment, Linux has a large number of cluster systems to choose from, suitable for different purposes and needs. 　　But it is not easy to determine which cluster should be used. Part of the problem is that terminology clusters are used on different occasions. IT managers may be concerned with how to make the server run longer or to make the application run faster, while mathematicians may be more concerned with large numbers on the server ...
