What is a data center? When the use of the Internet became widespread, companies and organizations could not maintain their servers themselves due to the high costs of this work. Therefore, in order to solve the problem of maintenance and repair of servers, data centers were created. Data Centers have made it possible to set up web servers for the general public by having high-speed connections to the Internet, as well as by having many powerful servers. By renting the space of these servers, companies and organizations publish their sites on the Internet and expose them to everyone. Of course, large companies with adequate capital generally rent a complete server from the data center and manage and control it remotely with special tools. We use it to store customer information and provide hosting services. In short, it can be said that the data center is a place where servers are kept under very favorable conditions.
Renting servers from datacenters and its costs are different depending on various parameters such as CPU speed, amount of RAM memory, server hard disk size, and the maximum monthly traffic provided to the server, as well as the operating system and type The data center is different.
Datacenters are connected to the Internet with strong connections and some with more than 12 different connections, and in case of a problem with any of the connections, they use another Internet and are always connected to the Internet. The most important issue in data centers is uninterrupted service, therefore, power outages, internet, etc. can interfere with the operation of the data center. Therefore, all data centers are equipped with large UPSs and very powerful generators for use in emergency power outages.
2 types of Rackmount or Desktop servers are usually used in data centers. Rackmount servers are smaller and occupy less space, but their prices are very high. These servers can be upgraded to a small extent, and therefore most data centers use desktop servers.
Due to the fact that most data centers use desktop servers, the buildings where these servers are kept have high ceilings for proper ventilation to keep the temperature of the said space low and prevent the servers from overheating. A part of the data centers is a control and monitoring room, where supervising engineers are busy with 24-hour control and review of all servers in the data center.
Servers are placed in enclosures called racks to be permanently secured in their place. In fact, the space of the data center is divided by racks. Each rack has a different size and depending on the size of the rack, a number of servers are placed inside it. The size of servers ranges from U1 to servers that occupy the entire floor of a rack.
In data centers, in addition to the above, the security and stability of servers is also very important. Cooling and fire extinguishing systems, power generators, etc. are all installed in all data centers for the stability and security of servers.
A data center can be a one-story or multi-story building where servers are kept on a number or entire floors. Rackmount servers stand in 19-inch racks and fill the racks in horizontal rows. . Corridors are placed between the racks for the server managers and the technical team to monitor and check the servers, the topic of data centers and their equipment is very complex and interesting, that’s why we recommend you to have two reports.
