Engineering System Of Data Centers (Part II)
Subsystem fire alarm and gas fire.
- Burglar alarms, access control subsystem (eg, using biometric data) and continuous video surveillance for visual verification of events.
Communication subsystem : Saturation of the data center network and server equipment determines the complexity of the communication infrastructure, which consists of the following components:
- Subsystem mortgages channels – for the protection and orderly laying low voltage and power lines.
- Cabling subsystem – for the formation of a single transmission medium information.
- Subsystem internal telephone for voice communication.
In the process of building infrastructure a data center, it may require additional construction work, such as ensuring the load capacity of overlap (up to 1 t / m 2), false ceilings etc.
Infrastructure subsystem is designed with the possibility of (planned) growth capacity of servers, network equipment and their connections without interrupting the information system. When building the capacity of the Redundant Data Centers, it is important to have relevant documentation of the current state of infrastructure and resources. Therefore, registration of documents are given special attention.
Reliability of redundant data centers infrastructure has an impact on the overall readiness of the information system. Due to the non-operational standards, even when using the most reliable equipment, it is impossible to provide the necessary access to information services. Therefore, it is important to pay special attention to design of infrastructure of Data Centers.

Data Center Tiers Classification
In this competitive world, just being at the first position on Internet is not enough. When it comes to Data Centers India, the owners should look beyond the current technologies to make their data centers really No. 1 in the Industry.
In the past few years Data Centers in India has really achieved a good place and name in the Data Centers World. To be a number one one should not just provide a good service but also requires to get ranked in Tiers.
Confused? Let me explain you. Data Centers are normally graded in Tiers. There are total four types of Tier System in Data Center. Tier I which is the most canonic and prostate when it comes to downtime and the Tier IV is the most beefy, redundant and fully-functional tier.
Basically, the Tier Grading is created by the Uptime Institute as a standard for trustworthy data centers and their infrastructure creation. The Tier grading is designed to aid the small and medium sized enterprises to select the best tier level data center for their businesses according to their requirements.
Different Tier level data centers offers various and advanced facilities such as power, cooling, emergency backup, fire suppression and the most important security. As the Tier Level grows so the features and facilities of that particular data center.
For any Data Center Services India, the above listed factors are much necessary to consider to achieve the Tier IV level. Not only the above but also there are many such elements which requires to be integrated in a data center such as bells and whistles.
Lets check out the Tier Levels of Data Centers and the availability if offers accordingly.
Tier I : It has single line for power and cooling distribution, offers 99.671% availability without redundant components.
Tier II : It has single line for power and cooling distribution, offers 99.741% availability and with redundant components.
Tier III : This level has multiple active power and cooling distribution lines but the only one path is active, redundant components, offers 99.982% availability and concurrently maintainable.
Tier IV : This the last and the top level for data centers which provides multiple active power and cooling distribution lines, redundancy, fault-tolerant and offers a 99.995% availability.
Unless the small and medium sized enterprises is involved in a big sector such as banking, they are not going to need the Tier IV redundancy. By looking the Tier levels any small and medium enterprises can easily determine the level where their enterprise operation lies.
