Hello, everyone!
Today, I will start to explain data center cabling. In this first article about data center cabling, I will explain basic information about data centers. Let's started.
Data center store and distribute huge amounts of data on the internet. A data center is a special building or part of a building in which a large number of servers, switches, routers, storages, etc. The data center is defined by a special standard – TIA-942.
Equipment in data centers is housed in racks. The data center should have a main and backup power supply - dual power distribution systems, dual generators, in addition, the use of UPS is mandatory. All devices should be connected to UPSs. All equipment and cables that have metal elements must be properly grounded. Power cables are usually under the floor and are separated from telecommunication cables. Special attention is paid to power supply and consumption. Data centers consume a huge amount of power. One of the tasks is to reduce power.

A constant temperature must be maintained in the data centers - there must be a hot air extraction system and a cooling system. Cooling is one of the big problems in data centers. Because that, it works to ensure optimal temperature, but at the same time to reduce power.
Equipment and data security is another very important detail. Millions are spent to secure data centers. Physical protection is needed - alarms, video cameras, people, as well as data protection from hackers.
The most popular data centers are Google, NSA, Facebook, Amazon, Apple, etc.
As I said, the main function of a data center is to store and distribute data. That is why storages and servers must be top quality. The amount of data stored and processed can be huge. Security of all data and speeds is required. The primary concept is speed. Data centers must be constantly active and available 24/7.
I will continue to explain this theme in the next article >> Data center cabling (2): Architecture.
Thank you!
