The World’s Largest Data Centers
This article analyses the facts and statistics around data centers.
In terms of electricity consumption, a large data center can use as much electricity as a small town. They have small containers loaded with thousands of servers each. With respect to their power density, it is over 100 times that of an office complex.
Characteristics of Data Centers
• 14% of the carbon foot print of the global IT sector is accounted for by data center.
• They store large amounts of data.
• As at 2011, about 35% of companies were expected to surpass the IT capacity in 18 months.
• The average age of modern data centers is 9 years old, any data center older than 7 years is considered outdated.
