DATA CENTRE: THE BRAIN OFTHE INTERNET

 

DATA CENTRE: THE BRAIN OF THE INTERNET



Globally, the number of  Internet users in the last decade (2011-2021) has increased drastically from 2000 million to 6000 million, but have we ever thought about how the internet works and how we get results of anything we type on the internet. Now here comes the requirement of the Data Centre. let us see what Data Centre is.

Data Center (American English) or Data Centre (British English) is a building or a room consisting of physical IT Equipments (Servers, Routers, Firewall, etc) to collect, store, processing, distributing, or allowing access to a large amount of data to the user and is well managed by the highly skilled IT professionals. For eg. when you google something over the internet, google searches it in its directory in the Data Centre located at some locations and then it sends back the stored data from its servers in the Data Centres to the user.

Now, since we know that Data Centres consists of physical IT equipment which means it requires power to operate and also backup power (Diesel Generators) to operate when there is a power failure for any type of maintenance in the power grid station. When the IT equipment operates it produces a lot of heat thus raising the temperature of the equipment, which if not maintained within the required parameters then the equipment might go fault. So here comes the idea of HVAC (Heating Ventilation and Air Conditioning) to maintain the temperature in the equipment. So Power and Temperature become the backbone of the Data Centres.

THE NEED FOR DATA CENTRES.

Let's suppose we started a small business where we need computers to stores our files and data's.In a span of time as we grow our business, our files and data will also grow parallelly and sometimes our computer's hard drive will not be sufficient to store our files and data and we land up buying servers of high storage which also requires a separate room as a server are not meant to keep anywhere as it is prone to dust and it also produces a lot of heat thus leading to the rise in temperature of the room which might affect the health of the equipment when it is not maintained in a required parameter thus leading us to buy an Air Condition where we have to spend really big and on top, it has to be operated 24*7 and we can only imagine its power consumption and Electricity Authority Bill.
So, To avoid all this hectic task of maintaining the safeguard of the data and the equipment by ownself, Data Centre's are built to provide us to safeguard our servers in a rented basis which will be looked after by highly skilled IT Professionals working in the Data Centre. They also guarantee that our servers never go off by any means be it a power failure or by a rise in temperature.

CLASSIFICATION OF DATA CENTRES.

Since Uptime Institute is the founder and trusted sources of Data Centre Tier Certification. They are the ones who have classified Data centres into four different Tiers according to the system availability and its infrastructure provided by the Data Centre. They are as follows.

1.Tier 1
  • This is a small level with infrastructure to support IT for office settings.
  • It protects against disruption from human errors but not an outage.
  • It has 99.671% of uptime in a year.
  • It has 28.8 hours of downtime per year.
  • It has to be shut down completely for preventive maintenance.
  • There is no redundancy.        
2.Tier 2
  • Tier 2 is the little upgraded version of Tier 1 with the addition of some components.
  • This has a safety against disruption.
  • It has 99.749% of uptime in a year.
  • It has 22 hours of downtime per year.
  • The component can be removed without shutting it down.
  • It has to be shut down completely for preventive maintenance.
  • In case of an unexpected shutdown, it will affect the system
3.Tier 3
  • This is a more upgraded version of Tier 2.
  • The Distribution path has redundancy to serve the critical environment.
  • It has 99.982% of uptime in a year.
  • It has 1.6 hours of downtime per year.
  • It is N+1 fault-tolerant.
  • The component can be removed without shutting it down.
  • In the case of preventive maintenance, it does not affect the system as it has redundancy on path distribution.
  • It has 72 hours of power outage protection.
4.Tier 4
  • This Tier has several physically isolated and independent systems for redundancy purpose.
  • Unlike all other Tiers (1,2,3), it is fault-tolerant.
  • It has 99.995% of uptime in a year.
  • It has 24 minutes of downtime per year.
  • In the case of preventive maintenance, it does not affect the system as it has redundancy on path distribution.
  • It is 2N+1 fault-tolerant.
  • It has continuous cooling that stable the environment.
  • In case of an unexpected shutdown, it will not affect the system.

Power Loads in Data Centre

Image
 As we all know, a Data Centre is a building with heavy Electrical machines, IT equipment, Mechanical machines, etc. To run this equipments/machines we need electric power either from Power station or Diesel generators. The power which we get from the power station is of High Tension Or High Voltage (11KV, 33KV) which is feed into HT panel which consists mostly of VCB (Vacuum Circuit Breaker) because while make and break operation it creates huge spark due to high voltage and current here is low but the potential difference charges the molecules of air of surrounding and gets charged during switching operation which creates huge arc which needs to be extinguished. Since Vacuum has high arc quenching property than air so the VCB is used in quenching the arc instead of ACB (Air Circuit Breaker), which is used in quenching the arc in LT( Low Tension/Voltage) side. HT panel is a metal enclosure with relays, circuit breaker, and energy meter used to receive high voltage power supply and...
