Data center usually refers to the centralized processing, storage, transmission, exchange and management of information in a physical space. The emergence of data centers has led to the understanding of people from the quantitative, structured world into the uncertain and unstructured world, which will gradually become a part of the infrastructure of modern society, just like transportation and network communication, and then have a positive impact on many industries.
Computer equipment, server equipment, network equipment, storage equipment, etc. are often considered to be the critical equipment in the core server room of a network. The environmental factors required for the operation of critical equipment, such as power supply system, cooling system, cabinet system, fire protection system, monitoring system, etc. are usually considered as the infrastructure of the critical room.
Data Center Development Process
The development trend of data center mainly starts from flexibility, green energy saving, modularity, integration, automation, stability and security, virtualization and cloud computing. The new generation data center should have the characteristics of virtualization, which can break the comfort between IP users and IP resources and make the complex system simplified. Virtualization is one of the important technologies that influence the development of the next generation data center. His advantage is to effectively improve the utilization efficiency of the data center, reduce the cost of the head, integration, optimization of existing server resources and performance, can be flexible, dynamic to meet the needs of business development. Virtualization allows data centers to host infrastructure resources can be taken at will like water and electricity. Closely linked to the virtualization business model is cloud computing, the core of cloud computing is virtualized resource sharing.
Data Center Components
Data center access is mainly divided into two categories: internet access and carrier access.
Data center using broadband ADSL access, the advantage of this method is that the bandwidth up to the cost of economic. The disadvantage is that the security is poor, the delay is slightly larger than the private line access.
Using LAN shared Internet access, this method is basically similar to ADSL access, single attention to access the need to do port mapping.
Using telephone line dial-up access. The access bandwidth of this method is narrower, so it is only applicable to the rental mode with fewer points and small amount of data.
The data center uses wireless network operators (such as: China Mobile, China Telecom and other operators) to provide channel access, and there are several connection methods in this way:
Using the mobile company room dedicated line access, this way of bandwidth (generally 2M), on the delay, security is very good, but the price of renting this dedicated line is more expensive. Particularly suitable for banks, POS unit network and other users who need a higher coefficient of safety, the case of a very large number of sub-stations is also recommended to use this method.
GPRS wireless access, this way in the data center to connect a GPRS MODEM, through the data center PC dial-up access. Advantages are rapid network organization and economical cost. The disadvantage is that the bandwidth is narrow (GPRS upstream 10kbps, downstream 40kbps), the delay is large. This method is more often used in testing. If you are going to use it in the actual project, you need to pay attention to the SIM card needs to apply for APN.
