Data centers are facilities that house servers and networking equipment which are critical for many business processes. They evolved from the large computer rooms of early computing. Data centers contain thousands of networked servers linked to the outside world via fiber optic cables. They provide redundant and secure infrastructure to ensure uninterrupted services. Key components include backup power generators, batteries, cooling systems, security cameras and access controls to protect data and ensure operations even during outages or disasters.

1. DATA CENTERS
T.Tejaswi

2. It is the brain of a company and the
place where the most critical processes

3. Data centers have their roots in the huge
computer rooms of the early ages of the
computing industry.
Early computer systems, complex to operate and
maintain, requires a special environment in which to
operate.

4. A server is a
computer program or
a machine capable of
accepting requests
from clients and
responding to
them. Their purpose
may be to share data
or hardware and
software resources
among clients. This
architecture is called
the client–
server model.

INTERNAL PARTS OF A WEB SERVER.

5. FIBER OPTIC CABLES USED IN DATACENTERS
Each data center houses
thousands of computer
servers, which are
networked together and
linked to the outside world
through fiber optic cables.
For ex:
Every time you share
information on Face book,
the servers in these data
centers receive the
information and distribute
it to your network of
friends.

6. Most small business owners keep their server, if they have one,
on a shelf in the corner of the office or perhaps locked in the
stationery cupboard.
They might have it connected to an UPS (Uninterruptible Power
Supply) so that if the electricity goes down the server will still keep
on working. This may also support the broadband router which
connects the server to the big wide world. It definitely doesn’t help
if the broadband line goes down for any reason

7. But what if
many…?
Then data centers comes
in….

8. The data centers host computers not one….
But many………………

9. Today in this digital world
every one needs
uninterrupted power
supply, so data centers
provide uninterrupted
power supply& if there’s
a delay until the second
power network takes over,
then BATTERIES jump
in…..
&&&&&&&&&&&&&&&&
of course the whole data
center is connected to
the internet………and
redundancy is
guaranteed with second
one..

10. What happens when there is a total fire accident,
earthquakes, floods……..?????????

12. Inside a Data center…

13. Many cables were necessary to connect all these
components , and the methods to accommodate and
organized these were devised ,such as standard
racks to mount equipment

14. Servers and storage units are located in standard racks in
especially secured server rooms .The racks are kept in an
enclosed area to enable optimal cooling.

15. Diesel Generators
When a power outage occurs, the diesel generators start up automatically
within seconds.The diesel generators then take over and provide the
complete power supply for the data center.

16. Batteries
Batteries can provide power during short outages, When
electricity fails completely.However,batteries cannot bridge
the gap for power outages that last longer than a few hours
or days.

17. Turbo-cooling units
High-efficiency cooling units remove the heat emitted by the
air conditioning system and release it into the outside air via
heat exchangers on the roof.

18. Control Station
Control stations for the IT and building security serve as command
central in the data center. All important information is displayed here on
large screens. Any variation from standard operation is promptly
reported.

19. Maximum security based on the higher standards of the
industry
SECURITY

20. Video Cameras
Multiple high-resolution video cameras monitor
the exterior premises and the building. The
cameras are arranged in such a manner that one
camera is also monitoring is still assured.

21. ADVANTAGES
1.Placed in a secure environment and it is safe.
2.Availability of batteries and generators when
electricity is not available.
3.They provide 24/7/365.
4.Highly secured by biometric etc-so others
cannot access or go inside a datacenter…
5.Protected by cameras inside and outside.
6.Cooling process is available-so they wont heat
up .
7.Secure the data even when a natural calamity
occur, because there will be a backup station.
8.Very less possibility of theft or loosing data

22. DISADVANTAGES
1.Access control (is given to others),
2.Stable systems required
3.Small server footprints(if not rack
optimized)
4.High cost

23. The shift of services to the cloud “is getting us to think about data
centers on a scale we never have before,” said Gates.
“Today in our data centers we have literally hundreds of
thousands of servers. In the future, we’ll have many millions of
those servers.”
