When we think about data center then it always comes a bigger picture in our mind. like huge size machines installed in bigger area, cutting off from city and loaded with multiple technologies etc.
let's have a look more about DataCenter and understand their types.
Definition of Dat Center
Its a facility area that provides shared access to applications and data using a complex network, compute, and storage infrastructure. It maintained with Industry standards w.r.t design, construction. its a highly secure area to ensure data secure & highly available. Now, type of data center vary on size which again depends on business needs. it could be small like one room to groups of geographically distributed buildings. It maintain on premises infrastructure with cloud or other technologies that contain compute and application.
Compute, Storage and Network are the three core technologies through ````````
Here are few examples.
Enterprise data centers :- Typically used by a single organization for their own internal purposes.
Colocation data centers :- Kind of rental property where the space and resources of a data center are made available to the people willing to rent it.
Managed service data centers :- Offer such as data storage, computing, and other services.
Cloud data centers : Distributed and offer to customer with the help of third party manage services.
Data Center Infrastructure
Data centers are a critical asset hence they are made up of power subsystems, uninterruptible power supplies (UPS), backup generators, ventilation and cooling equipment, fire suppression systems and building security systems etc. These are defined under industry standards and segregated under below four tier categories
Tier 1: A Tier 1 data center has a single path for power and cooling and few, if any, redundant and backup components. It has an expected uptime of 99.671% (28.8 hours of downtime annually).
Tier 2: A Tier 2 data center has a single path for power and cooling and some redundant and backup components. It has an expected uptime of 99.741% (22 hours of downtime annually).
Tier 3: A Tier 3 data center has multiple paths for power and cooling and systems in place to update and maintain it without taking it offline. It has an expected uptime of 99.982% (1.6 hours of downtime annually).
Tier 4: A Tier 4 data center is built to be completely fault-tolerant and has redundancy for every component. It has an expected uptime of 99.995% (26.3 minutes of downtime annually).
Conclusion
Even as the world of cloud computing continues to grow with stricter regulations and higher customer expectations, we’re seeing a return to the data center, often in a network of smaller “Edge” or “micro” data centers.
If you are planning to setup your data center than be careful about your requirement which not only save your cost but also fulfill right expectations.
