== DATA CENTER HUMOR ==[edit]

  • National Mutual: "When the fire alarm goes off, you have 30 seconds to clear the floor, then the doors lock. Halon gas is then released. .. Halon gas is perfectly safe ... It's the lack of oxygen which kills you.".
  • Backup generators always fail to start UNTIL AFTER the battery banks have been exhausted.
  • 9-track ibm tape write protect rings make great frisbees on a slow graveyard shift.
  • The BIG RED push button really does power down the whole floor.
  • You can never find a tile-lifter when you need one.
  • ICL Mainframes had prettier blinking lights than the IBM big iron.

History[edit]

Here is a revised version of the history section. Some information was taken out and a Section on the cost of space was added. Please contact me if these changes can be added to the article. Heronhaus (talk) 18:39, 17 September 2016 (UTC)

Data centers have their roots in the huge computer rooms of the early ages[when?] of the computing industry. Early computer systems, complex to operate and maintain, required a special environment in which to operate. Many cables were necessary to connect all the components, and methods to accommodate and organize these were devised such as standard racks to mount equipment, raised floors, and cable trays (installed overhead or under the elevated floor). A single mainframe required a great deal of power, and had to be cooled to avoid overheating. Security became important – computers were expensive, and were often used for military purposes. Basic design-guidelines for controlling access to the computer room were therefore devised.

As information technology (IT) operations started to grow in complexity, organizations grew aware of the need to control IT resources. The advent of Unix from the early 1970s led to the subsequent proliferation of freely available Linux-compatible PC operating-systems during the 1990s. These were called "servers", as timesharing operating systems like Unix rely heavily on the client-server model to facilitate sharing unique resources between multiple users. The availability of inexpensive networking equipment, coupled with new standards for network structured cabling, made it possible to use a hierarchical design that put the servers in a specific room inside the company. The use of the term "data center", as applied to specially designed computer rooms, started to gain popular recognition about this time.[citation needed]

The boom of data centers came during the dot-com bubble of 1997–2000. Companies needed fast Internet connectivity and non-stop operation to deploy systems and to establish a presence on the Internet. Installing such equipment was not viable for many smaller companies. Many companies started building very large facilities, called Internet data centers(IDCs), which provide commercial clients with a range of solutions for systems deployment and operation. New technologies and practices were designed to handle the scale and the operational requirements of such large-scale operations. These practices eventually migrated toward the private data centers, and were adopted largely because of their practical results. Data centers for cloud computing are called cloud data centers (CDCs). But nowadays, the division of these terms has almost disappeared and they are being integrated into a term "data center".

With an increase in the uptake of cloud computing, business and government organizations scrutinize data centers to a higher degree in areas such as security, availability, environmental impact and adherence to standards. Standards documents from accredited professional groups, such as the Telecommunications Industry Association, specify the requirements for data-center design. Well-known operational metrics for data-center availability can serve to evaluate the commercial impact of a disruption. Development continues in operational practice, and also in environmentally-friendly data-center design.


Cost of space. Real estate prices vary greatly according to the geographic location of the data center. For example, in early 2003, the commercial property prices in San Francisco were almost double those in other markets, such as Chicago A comprehensive data center cost model must account for such variance in real estate price. o Recurring cost of power. The electricity costs associated with continuous operation of a data center are substantial; a standard data center with a thousand racks spread over an area of 30,000 ft2 requires about 10 MW of power for the computing infrastructure. The direct cost of drawing this power from the grid should be included. o Maintenance, amortization of the power delivery, conditioning and generation. Data centers are a critical resource with minimally affordable downtime. As a result, most data centers are equipped with back-up facilities, such as batteries/fly-wheel and on-site generators. Such back-up power incurs installation and maintenance costs. In addition, the equipment is monitored continuously, and costs associated with software and outsourced services must be included.

Extensive rewrite needed[edit]

Not just for the copyvios, but do we really need seven sections on design? Timtempleton (talk) 18:42, 28 February 2017 (UTC)
