The internet is used in virtually every country of the world, although the penetration differs from country to country. We cannot talk about the Internet without mentioning the role that data center racks have played in its continued operation in today's world. But for us to fully understand the role of data center racks in modern day telecommunications, we need to know about how they came about.
The internet is used in virtually every country of the world, although the penetration differs from country to country. We cannot talk about the Internet without mentioning the role that data center racks have played in its continued operation in today's world. But for us to fully understand the role of data center racks in modern day telecommunications, we need to know about how they came about.
In the early days of computing, the first generation computers were very large computers that filled entire rooms (which had special designs). They were complex to operate and maintain, and because they used a lot of power, they needed to be cooled to avoid overheating.
As advances in technology made computers smaller, these rooms were largely abandoned, but found use once again as the advent of the Internet, the dot-com boom and subsequent bubble of the mid 1990s ushered in an era of the use of inexpensive networking equipment and more sophisticated information and computer technology.
Thus was born the era of the data centers, which are specially designed areas used as control centers (or command posts if you like) to house the equipment on which the Internet and the IT backbone of many industries operate.
A typical data center houses routers and servers, which are kept on wall mounted data racks. The physical environment of one is vigorously controlled. The operations of the equipment heats up the air in the data center, and an increase in the temperature will lead to equipment malfunction. To achieve adequate center rack cooling and optimum humidity, economizer cooling is used. Modern economizer cooling systems use external air to achieve data center rack cooling, thus saving on energy.
The amount of data center rack space to be created in one depends on the size of the server equipment. When allocating rack space, provision is also made in the physical design for installation of fire alarms, fire fighting sprinklers, security equipment such as surveillance cameras and the use of elevated flooring systems.
Another important component of data centres is the magnetic data tape storage racks. The use of magnetic tape to store data has been on for more than half a century. Its use has not diminished, but has undergone modifications over this time. It costs a lot less to retain information in magnetic tape, and so appropriate data tape storage racks are still found in data centers across the world.
So next time you log into your computer to access the internet, spare a thought to how the work of so many people over the years has made it all possible.
