· Always be able to provide information to the object that it should serve.
· Always ready to respond to natural disasters as well as from errors accidentally or intentionally by human beings.
In other words, information systems should always be able to meet the needs of social and economic activities in every moment, every situation is different.
From the above needs, the enterprises in general must take into account "Data Center - Data Center - DC" with all sizes to collect, process, store, and provide data to fully satisfy the the needs of the business, providing high efficiency in economic terms, the security of business operations.
Data Center, said simply, is home to large computer systems and related components such as transmission systems and storage systems. This center is designed to ensure the availability and high security for data with redundant power supplies, redundant data connections, these devices ensure stable operating environment for the PC ( air conditioning, fire ..) and the security system (including the permanent elements of the population).
A. Reasons for Using Data Centers
Data Center is the only solution and the most appropriate to ensure the information system of a unit with high availability along with the best level of security. Data centers and computing centers can say is the gathering place is the pinnacle of technology areas such as electricity, refrigeration, management and control, fire control, networks, servers, security information security ... so the construction and operation of a data center and computer center toanla a serious job, which requires high professionalism. This is a job that most enterprises can not undertake or to consider themselves more efficient deployment (for large enterprises). Therefore, construction and operation of this center by the professional corporation; Center used by businesses, government agencies is one approach being implemented in many parts of the world as in developed countries development as the U.S., Europe, or the developing countries of Southeast Asia such as Malaysia, Thailand, Singapore. Using the services and data center-centric computing center of the other units, will ensure that businesses get the funding estimates for stable operation and reduction of financial problems in business processes his.
2. Data Center Model
Data center now has a structure's technology research and identify the components as well as the quality (level) difference. The model illustrates an overview of the components of a data center as well as the presence or in the presence of different levels of data center.
3. the data center level
The data center can target different activities, the level of investment, operating methods, geographical conditions, the environment where ... Level Center, known as TIER standards, the Data Center Data is a measure of the ability to provide services of Data Center in the normal conditions as well as when problems such as power failure, loss of transmission lines and damaged equipment, equipment maintenance, fire explosion ...
Specifically, the

(*) If you build a standard Data Center Tier III + and able to upgrade to the TIER IV redundant design is 2 (N +1).
