Internet Protocol. ISCSI Qualified Name. Internet Small Computer System Interface. Internet Storage Name Service. Just a Bunch of Disks. A drive enclosure that is directly attached to a host. In an iSCSI network, a frame that can contain 9000 bytes for large data transfers. A normal frame can contain 1500 bytes. Kilobyte. Equivalent to 1000 bytes for data storage and statistics, or 1024 bytes for memory. See local area network (LAN). A disk drive that contains metadata but is no longer part of a virtual disk. A communications infrastructure designed to use dedicated wiring over a limited distance (typically a diameter of less than five kilometers) to connect to a large number of intercommunicating nodes. Ethernet and token ring are the two most popular LAN technologies. (SNIA) The SCSI identifier of a logical unit within a target. (SNIA) For example, a LUN identifies the mapping between a storage system volume and a port on a switch or HBA/NIC. Indicates the unique ID of a node in FC loop topology. A loop address is sometimes referred to as a Loop ID. See Fibre Channel-Arbitrated Loop (FC-AL). See logical unit number (LUN). The processor (located in a controller module) that is primarily responsible for human-computer interface and computer-computer interface functions, and interacts with the Storage Controller. 268 HP StorageWorks 2000 Family Modular Smart Array CLI reference guide • May 2008
