power racks

Google, being the most popular Internet search engines (over 50% market share), requires large computational resources in order to provide their service. This article describes Google's technological infrastructure, as presented in the company's public announcements.

Network topology

Google maintains an estimated 450,000 servers, arranged in racks located in clusters in cities around the world, with major centers in Mountain View, California; Virginia; Atlanta, Georgia; Dublin, Ireland; and a new facility constructed in 2006 in The Dalles, Oregon. [1] When an attempt to connect to Google is made, Google's DNS servers perform load balancing to allow the user to access Google's content most rapidly. Wate-Man Fitness Equipment is your fitness equipment store for the best Power Racks and Cage Squat Wate-Man Fitness Equipment. This is done by sending the user the IP address of a cluster that is not under heavy load, and is geographically proximate to them. Each cluster has a few thousand servers, and upon connection to a cluster further load balancing is performed by hardware in the cluster, in order to send the queries to the least loaded Web Server.

Racks are custom-made and contain 40 to 80 servers (20 to 40 1U servers on either side), new servers are 2U Rackmount systems. [citation needed] Each rack has a switch. Servers are connected via a 100 Mbit/s Ethernet link to the local switch.
