OpenSSI is an open source single-system image clustering system. It allows a collection of computers to be treated as one large system, allowing applications running on any one machine access to the resources of all the machines in the cluster.〔 〕 OpenSSI is based on the Linux operating system and was released as an open source project by Compaq in 2001.〔 〕 It is the final stage of a long process of development, stretching back to LOCUS, developed in the early 1980s. ==Description== OpenSSI allows a cluster of individual computers (''nodes'') to be treated as one large system. Processes run on any node have full access to the resources of all nodes. Processes can be migrated from node to node automatically to balance system utilization. Inbound network connections can be directed to the least loaded node available. OpenSSI is designed to be used for both high performance and high availability clusters. It is possible to create an OpenSSI cluster with no single point of failure, for example the file system can be mirrored between two nodes, so if one node crashes the process accessing the file will ''fail over'' to the other node. Alternatively the cluster can be designed in such a manner that every node has direct access to the file system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OpenSSI」の詳細全文を読む スポンサード リンク
