A data center is a facility that centralizes an organization’s shared IT equipment and operations for the purpose of storing, processing, and disseminating data and applications. Because they house an organization’s most critical and proprietary assets, data centers are vital to the continuity of day-to-day operations.

Types of data centers?

There are four main types of data centers:

  • Enterprise data centers. These are created, owned and operated by companies and are optimized for their end users.
  • Managed services data centers.
  • Colocation data centers.
  • Cloud data centers.

Data center business?

A data center (or data center) is a facility made up of computers and networked storage that businesses and other organizations use to organize, process, store, and disseminate large amounts of data.

How to build a networked data center?
8 steps to building a modern data center

  • Be modular.
  • Convergence when possible.
  • Let the software do the driving.
  • Adopt basic hardware.
  • Empower end users.
  • Break down silos.
  • What a hybrid.
  • Focus on continuity of service

Why do you need a data center?

Data centers offer the capabilities – scalability, security, efficiency, and state-of-the-art technology – that businesses and organizations are demanding more and more, but are too expensive to do on their own. Data migration goes a long way; from safety and reliability to energy efficiency and cost reduction.

What Makes a Good Data Center?

Data centers must use software and technology that protect their assets, but they must also have strong physical security. Your facility should have adequate locks, surveillance and, depending on the size, even security personnel.

How are data centers connected?

Basically, a data center connects to the Internet like any other user: through the line of a dedicated service provider. However, unlike a typical building, data centers have multiple connections available from different vendors, allowing them to offer a variety of options to their customers.

Who has more data centers?

While the majority of the 504 hyperscale installations (40 percent) are in the US, the highest growth rates have been in Europe and Asia-Pacific. China, Japan, the UK, Germany and Australia now account for 32 percent of the total. Amazon and Microsoft launched more than half of all new data centers in the last 12 months.

Network

A network consists of two or more computers that are connected to share resources (such as printers and CDs), exchange files, or allow electronic communications. Computers on a network can be connected through cables, telephone lines, radio waves, satellites, or rays of infrared light.

Two common types of networks:

Local area network (LAN)
Wide Area Network (WAN)

Local area network

A local area network (LAN) is a network that is limited to a relatively small area. It is usually limited to a geographic area such as a writing lab, school, or building.

Computers connected to a network are broadly classified as servers or workstations. Servers are not generally used directly by humans, but rather run continuously to provide “services” to the other computers (and their human users) on the network. The services provided may include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, full access control (security) for network resources, and many others.

Workstations are so named because they typically have a human user interacting with the network through them. Workstations were traditionally considered a desktop computer, consisting of a computer, keyboard, screen, and mouse, or a laptop, with an integrated keyboard, display, and touchpad. With the advent of the tablet and touch screen devices such as iPad and iPhone, our definition of workstation is rapidly evolving to include those devices, due to their ability to interact with the network and use network services.

Servers tend to be more powerful than workstations, although configurations are driven by need. For example, a group of servers may be located in a safe area, away from humans, and can only be accessed through the network. In such cases, it would be common for servers to function without a dedicated display or keyboard. However, the size and speed of the server’s processors, hard drive, and main memory can dramatically increase the cost of the system. On the other hand, a workstation may not need as much storage or working memory, but it might require an expensive display to fit the needs of its user. Each computer on a network must be properly configured for use.

In a single LAN, computers and servers can be connected via cables or wirelessly. Wireless access to a wired network is possible through wireless access points (WAP). These WAP devices provide a bridge between computers and networks. A typical WAP may have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although the practical capacity may be much less.

Servers will almost always be wired to the network, because wired connections are still the fastest. Workstations that are stationary (desktop computers) are also often wired to the network, although the cost of wireless adapters has been reduced to the point that by installing workstations in an existing wired installation inappropriate, it may be easier and less expensive to use wireless technology for a desktop computer.

See the topology, cabling, and hardware sections of this tutorial for more information on setting up a LAN.

Wide area network

Wide Area Networks (WANs) connect networks in larger geographic areas, such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplinks can be used to connect this type of global network.

With a WAN, Florida schools can reach places like Tokyo in seconds, without having to pay huge phone bills. Two users half a world away with workstations equipped with microphones and webcams can teleconference in real time. A WAN is complicated. It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks such as the Internet. To users, however, a WAN will not seem much different than a LAN.
