header HiPPI hop count host hot swappable HSSDC HSSDC-2 HTTP hub hunt group I2C ICT Idle ID_ID iFCP iFCS IFL in-band initiator Insistent Domain ID Mode integrated fabric The portion of a Fibre Channel frame that contains control and addressing information associated with the frame. High-Performance Parallel Interface. An 800 Mbps interface normally used in supercomputer environments. The number of ISLs a frame must traverse to get from its source to its destination. A computer system that provides end users with services, such as computation and storage access. Description of a replacement unit that can be substituted for a defective unit while the subsystem is running (performing its normal function). High-speed serial data connection. A form factor that allows quick connections for copper interface. A second-generation HSSDC connector. See also HSSDC. Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on the World Wide Web. A Fibre Channel wiring concentrator that collapses a loop topology into a physical star topology. Nodes are automatically added to the loop when they are active and removed when they are inactive. A number of N_Ports registered as a single Alias_ID so that the fabric can route a word to a port that is not busy. Inter-integrated circuit. A type of bus used to connect integrated circuits (ICs). Intracircuit test. Continuous transmission of an ordered set over a Fibre Channel link when no data is being transmitted in order to keep the link active and maintain bit, byte, and word synchronization. Insistent domain ID. A parameter of the configure command in Fabric OS. Internet Fibre Channel Protocol. A protocol that supports Fibre Channel Layer 4 FCP-Over-TCP/IP. It is a gateway-to-gateway protocol in which TCP/IP switching and routing components enhance/replace Fibre Channel fabric. IP storage fabric configuration server. Interfabric link. A connection between a router and an edge fabric. Architecturally, such connections can be of type EX_Port-to-E_Port or EX_Port-to-EX_Port. Transmission of management protocol over the Fibre Channel. A server or workstation on a Fibre Channel network that initiates communications with storage devices. See also target. Sets the domain ID of a switch as insistent, so that it remains the same over reboots, power cycles, failovers, and fabric reconfigurations. This mode is required to support FICON traffic. See ID_ID. The fabric created by an HP StorageWorks SAN Switch Integrated/64, consisting of six HP StorageWorks 1 GB switches cabled together and configured to handle traffic seamlessly as a group. 16 Glossary
