ESI ESP event Event Information Packet Event Number Evt No. exabyte Enclosure Services Interface. The SCSI-3 engineering services interface implementation developed for storage products. A bus that connects the EMU to the disk drives. Enclosure Services Processor. An EMU that implements an enclosure's services process. Any significant change in the state of the Enterprise storage system hardware or software component reported by the controller to HP P6000 Command View. See also controller event, drive enclosure event, management agent event, and termination event. See EIP. A sequential number assigned to each Software Code Identification (SWCID) event. It is a decimal number in the range 0-255. See Event Number. A unit of storage capacity that is the equivalent of 260 bytes or 1,152,921,504,606,846,976 bytes. One exabyte is equivalent to 1,024 petabytes. F fabric fabric port failover failsafe fan FATA Fault Management Code FC HBA FCA FCC FCP fiber fiber optic cable fiber optics Fibre Channel Fibre Channel adapter Fibre Channel drive enclosure Fibre Channel Loop field replaceable unit A network of Fibre Channel switches or hubs and other devices. A port which is capable of supporting an attached arbitrated loop. This port on a loop will have the AL_PA hexadecimal address 00 (loop ID 7E), giving the fabric the highest priority access to the loop. A loop port is the gateway to the fabric for the node ports on a loop. See array controller failover or DR group failover. A safe state that devices automatically enter after a malfunction. Failsafe DR groups stop accepting host input and stop logging write history if a group member becomes unavailable. The variable speed airflow device that cools an enclosure or component by forcing ambient air into an enclosure or component and forcing heated air out the other side. Fibre Attached Technology Adapted disk drive. See FMC. Fibre Channel Host Bus Adapter. See also FCA. Fibre Channel Adapter. See also FC HBA. Federal Communications Commission. The federal agency responsible for establishing standards and approving electronic devices within the United States. Fibre Channel Protocol. The optical media used to implement Fibre Channel. A transmission medium designed to transmit digital signals in the form of pulses of light. Fiber optic cable is noted for its properties of electrical isolation and resistance to electrostatic contamination. The technology where light is transmitted through glass or plastic (optical) threads (fibers) for data communication or signaling purposes. A data transfer architecture designed for mass storage devices and other peripheral devices that require high bandwidth. See FCA. An enclosure that provides 12-port central interconnect for Fibre Channel arbitrated loops following the ANSI Fibre Channel disk enclosure standard. Fibre Channel Arbitrated Loop. The American National Standards Institute's (ANSI) document that specifies arbitrated loop topology operation. See FRU. 136 Glossary
