E Enterprise network A geographically dispersed network under the backing of one organization. Enterprise Storage Server® Provides an intelligent disk storage subsystem for systems across the enterprise. Event In the Tivoli environment, any significant change in the state of a system resource, network resource, or network application. An event can be generated for a problem, for the resolution of a problem, or for the successful completion of a task. Examples of events are the normal starting and stopping of a process, the abnormal termination of a process, and the malfunctioning of a server. F Fabric The Fibre Channel employs a fabric to connect devices. A fabric can be as simple as a single cable connecting two devices. The term is often used to describe a more complex network utilizing hubs, switches, and gateways. FC See Fibre Channel. FCS See Fibre Channel standard. Fiber optic The medium and the technology associated with the transmission of information along a glass or plastic wire or fiber. Fibre Channel A technology for transmitting data between computer devices at a data rate of up to 1 Gb. It is especially suited for connecting computer servers to shared storage devices and for interconnecting storage controllers and drives. Fibre Channel Arbitrated Loop A reference to the FC-AL standard, a shared gigabit media for up to 127 nodes, one of which can be attached to a switch fabric. See also arbitrated loop and loop topology. Refer to American National Standards Institute (ANSI) X3T11/93-275. Fibre Channel standard An ANSI standard for a computer peripheral interface. The I/O interface defines a protocol for communication over a serial interface that configures attached units to a communication fabric. Refer to ANSI X3.230-199x. File system An individual file system on a host. This is the smallest unit that can monitor and extend. Policy values defined at this level override those that might be defined at higher levels. G Gateway In the SAN environment, a gateway connects two or more different remote SANs with each other. A gateway can also be a server on which a gateway component runs. H Hardware zoning Hardware zoning is based on physical ports. The members of a zone are physical ports on the fabric switch. It can be implemented in the following configurations: one to one, one to many, and many to many. HBA See host bus adapter. 752 IBM Tivoli Storage Manager Implementation Guide
