Data center are basically physically more prone to attacks than the problem of softwares. These physical factors apparently an average user will never think of. Previously we have published various articles on Data Center like Data Center Disaster Management, Data Center and Choice of Storage, Building Your Own Data Center and the Points Determining a Perfect Data Center. Today in this article we will discuss the primary factors which are very basic but are the corner stone for keeping a Data Center running.
Security for entry into a Data Center is the most crucial factor
A data center is a physical place that must first be physically secured : the server on the inside, as well as other devices are in operation; this implies a set of rules related to safety. The data centers are monitored, often by armed guards, both outside and inside them; access is regulated very precisely the human who are accessing there is dedicated badge to the individual and in the data center entry is compartmentalized. The employee who is responsible for a particular service can access only a few rooms.
In many data center automation plays a central role on the security front, everything is authorized by the Government and the cameras and scanning of the entry to the rooms are controlled externally.
Why this level of security ? The data and information contained in a data center is very valuable, in the case of financial data, of course, this value increases, therefore, for a bank, a data center has very high safety standards.
A data center is interconnected with several operators with the rest of the world
Within a data center usually there are various network operators, national and international. This is to ensure that the data center is connected with more lines towards the outside and can communicate through more operators – there are dedicated channels and the channels leading to the interchanging points. Depending on the size of the ISP that manages the data center and the nature of the data center the scope of bandwidth can vary – from some hundred Mbit / s to several Gbit /s.
The bandwidth used is obviously has a cost, so it is managed carefully, usually by a department specifically in charge of the network data. The people of this department also deal with the design and optimize in an way in which that data center can reach certain foreign countries, there may be special requirements for customers who need to achieve low latency, some destinations in the world, and this often involves a lot of work acquisition of sections of other operators, the routing on your network.
The higher cost of a data center is often the cooling
A good proportion is spent to cool the data center, obviously trying to achieve the best possible efficiency. The cooling is an important item in the energy consumption and machines need to stay within a controlled temperature, which varies depending on the technology and the strategies employed by the operator of data centers. We have a separate article on Data Center Cooling.
