    Abstract: The invention provides a file server system (100) and a method for operating that system, which is easily scalable in number and type of individual components. A plurality of file servers (110) are coupled using inter-node connectivity, such as an inter-node network, (120) so that any one node (111) can be accessed from any other node (111). Each file server includes a pair of file server nodes (111), each of which has a memory and each of which conducts file server operations by simultaneously writing to its own memory and to that of its twin, the pair being used to simultaneously control a set of storage elements (112) such as disk drives. File server requests directed to particular mass storage elements (112) are routed among file servers (110) using an inter-node switch and processed by the file servers (110) controlling those particular storage elements (112). The mass storage elements (112) are disposed and controlled to form a redundant array, such as a RAID storage system. The inter-node network (120) and inter-node switch are redundant, so that no single point of failure prevents access to an individual storage element. The file servers (110) are disposed and controlled to recognize failure of any single element in the file server system (100) and to provide access to all mass storage elements (112) despite any such failures.

    Abstract translation: 本发明提供了一种文件服务器系统（100）和一种用于操作该系统的方法，该系统在各个组件的数量和类型上容易扩展。 使用诸如节点间网络的节点间连接（120）来耦合多个文件服务器（110），使得可以从任何其他节点（111）访问任何一个节点（111）。 每个文件服务器包括一对文件服务器节点（111），每个文件服务器节点（111）具有存储器，并且每个文件服务器节点（111）具有存储器，并且每个文件服务器节点通过同时写入其自己的存储器和其双工进行文件服务器操作， 一组存储元件（112），例如磁盘驱动器。 指向特定大容量存储元件（112）的文件服务器请求使用节点间交换机在文件服务器（110）之间路由，并由控制那些特定存储元件（112）的文件服务器（110）进行处理。 大容量存储元件（112）被布置和控制以形成诸如RAID存储系统的冗余阵列。 节点间网络（120）和节点间交换机是冗余的，使得没有单个故障点阻止访问单个存储元件。 文件服务器（110）被布置和控制以识别文件服务器系统（100）中的任何单个元件的故障，并且尽管存在任何这样的故障来提供对所有大容量存储元件（112）的访问。
