服务器农场（Server farm）或服务器集群（Server cluster）是计算机服务器的一个集合-通常被一个组织维护，所提供的服务器功能方面远远超过单个服务器的能力。服务器农场往往由几千个计算机构成，这需要大量的电力来运行，并保持服务器的冷却。在最佳的性能水平上，服务器农场具有在财政的和环境的与其关联的巨大成本。服务器农场通常具有备份服务器，在主服务器故障的情况下，备份服务器可以接管主服务器的功能。服务器农场一般是搭配有网络交换机和/或路由器，在群集不同部分与在集群用户之间能够互相通信。服务器农场通常把计算机，路由器，电源，以及相关的电子产品都装入在服务器机房或数据中心的19英寸机架中。

A server farm or server cluster is a collection of computer servers - usually maintained by an organization to supply server functionality far beyond the capability of a single machine. Server farms often consist of thousands of computers which require a large amount of power to run and to keep cool. At the optimum performance level, a server farm has enormous costs (both financial and environmental) associated with it. Server farms often have backup servers, which can take over the function of primary servers in the event of a primary-server failure. Server farms are typically collocated with the network switches and/or routers which enable communication between the different parts of the cluster and the users of the cluster. Server farmers typically mount the computers, routers, power supplies, and related electronics on 19-inch racks in a server room or data center.
