Serverfarm

A server farm is a group of similar, networked server hosts that are connected to a logical system (also: Data Center ). It optimizes the internal processes by distributing the load between each server and speeds up the computer processes by utilizing the processing power of multiple servers. A server farm using an appropriate software for load balancing.

The advantage of server farms located in the central administration and horizontal scalability, enabling quick and easy adaptation to growth and changes in customers' requirements by adding more hosts. Redundant interpretation of the infrastructure, such as double cabling, redundant power supply and grid connection a high level of reliability is achieved.

Improve server farms, the use of IT resources (English " resources" ) and increase the availability, performance and security of applications. The parallel server structures with appliance servers provide a very high data throughput and allow the simultaneous access of many users.

Google operates is estimated that about 1 million of the world's approximately 33 million computer servers. The spaces for the required cooling systems (water cooling, air conditioning, air blower ) are now larger than the corresponding computer labs. In addition, many servers are operated in parallel ( redundant ) the safety, resulting in an average utilization of so far only about 20%. To improve the energy efficiency, and controls the components to be optimized. In addition, server farms are now also in climatically favorable, since cooler, regions established to reduce the cost of cooling: In June 2013 Facebook opened its first European server farm in Sweden, Lulea.
