SSN storage carrier storage pool storage system Storage System Name switch Storage System Name. An HP Command View EVA-assigned, unique 20-character name that identifies a specific storage system. See carrier. The aggregated blocks of available storage in the total physical disk array. The controllers, storage devices, enclosures, cables, and power supplies and their software. See SSN. An electro-mechanical device that initiates an action or completes a circuit. symbols and numbers 3U A unit of measurement representing three "U" spaces. "U" spacing is used to designate panel or enclosure heights. Three "U" spaces is equivalent to 5.25 inches (133 mm). See also rack-mounting unit. µm A symbol for micrometer; one millionth of a meter. For example, 50 µm is equivalent to 0.000050 m. T TC Termination Code termination event terminator topology transceiver Termination Code. An Enterprise Storage System controller 8-character hexadecimal display that defines a problem causing controller operations to halt. See also IDX and param. See TC. Occurrences that cause the storage system to cease operation. Interconnected elements that form the ends of the transmission lines in the enclosure address bus. An interconnection scheme that allows multiple Fibre Channel ports to communicate. Point-to-point, arbitrated loop, and ed fabric are all Fibre Channel topologies. The device that converts electrical signals to optical signals at the point where the fiber cables connect to the FC elements such as hubs, controllers, or adapters. U uninitialized system UNRECOVERABLE Condition unwritten cached data UPS A state in which the storage system is not ready for use. See also initialization. A drive enclosure EMU condition report that occurs when one or more elements inside the enclosure have failed and have disabled the enclosure. The enclosure may be incapable of recovering or bypassing the failure and will require repairs to correct the condition. This is the highest level condition and has precedence over all other errors and requires immediate corrective action. Also called unflushed data. See also dirty data. Uninterruptible Power Supply. A battery-operated power supply guaranteed to provide power to an electrical device in the event of an unexpected interruption to the primary power supply. Uninterruptible power supplies are usually rated by the amount of voltage supplied and the length of time the voltage is supplied. V virtual disk virtual disk family Variable disk capacity that is defined and managed by the array controller and presented to hosts as a disk. May be called Vdisk in the user interface. A virtual disk and its snapshot, if a snapshot exists, constitute a family. The original virtual disk is called the active disk. When you first create a virtual disk family, the only member is the active disk. See also active virtual disk, and virtual disk snapshot. 178 Glossary
