fault-tolerant virtual disk FC FC-AL Fibre Channel (FC) Fibre ChannelArbitrated Loop (FC-AL) field-replaceable unit (FRU) FRU Gbyte (GB) global spare HBA HIM A virtual disk that provides protection of data in the event of a single disk drive failure by employing RAID 1, 3, 5, 6, 10, or 50. RAID 6 also provides protection against the failure of two drives. See Fibre Channel (FC). See Fibre Channel-Arbitrated Loop (FC-AL). A serial I/O bus capable of supporting multiple protocols, including access to open system storage (FCP protocol), access to mainframe storage (FICON protocol), and IP. Fibre Channel supports point to point, arbitrated loop, and switched topologies. (SNIA) A form of Fibre Channel network in which up to 126 nodes are connected in a loop topology, with each node's L_Port transmitter connecting to the L_Port receiver of the node to its logical right. Nodes connected to a Fibre Channel Arbitrated Loop arbitrate for the single transmission that can occur on the loop at any instant using a Fibre Channel Arbitrated Loop protocol that is different from Fibre Channel switched and point-to-point protocols. An arbitrated loop may be private (no fabric connection) or public (attached to a fabric by an FL_Port). (SNIA) An assembly component that is designed to be replaced on site, without the system having to be returned to the manufacturer for repair. See field-replaceable unit (FRU). Gigabyte. Equivalent to 1000 Kbyte for data storage and statistics, or 1024 Mbyte for memory. A spare disk drive that is available to all virtual disks in a system. See host bus adapter (HBA). Host interface module. 308 HP StorageWorks 2000 Family Modular Smart Array reference guide • August 2008
