This is a user-definable entity used by Microsoft Cluster Server (MSCS) software. A hardware device that facilitates communications between a host and one or more devices organized on an RA4000. A device that provides an interface between a host system (server) and storage system or other devices connected on a fibre channel arbitrated loop or fabric. A storage device including disk drives and one or more resident array controllers. A misunderstood command sent by software that causes processing to halt. An automatically assigned address that comes from an unused IP address pool. When the client/server session ends, the IP address is returned to the pool. The server can use fewer IP addresses to communicate with clients. Clients do not need to provide a hard-coded address to the server. A standard network protocol that primarily operates on a physical level, using network interface cards and cabling to transmit data between computers. Transfer rates are normally 1,000 or 10,000 megabits per second. The process of moving the operation of a previously failed cluster group from the secondary cluster node back to the primary node. The process of moving the operation of a cluster group from the primary node to the secondary node in the same cluster. A design concept that allows continued operation of a computer entity when a fault (or failure) is encountered. Tolerance is achieved primarily by designing redundant elements into the entity.
