Fibre Channel (FC) SAN Definitions

  • B

    block storage

    Block storage is a type of data storage typically used in storage-area network (SAN) environments where data is stored in volumes, also referred to as blocks.

  • buffer credits or buffer-to-buffer credits (BBCs)

    Buffer credits, also called buffer-to-buffer credits (BBCs), allow data communication in a Fibre Channelstorage area network (SAN) where there are long spans of fiber opticcable.

  • C

    converged network adapter (CNA)

    A converged network adapter (CNA) is a single network interface card (NIC) that contains both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet NIC.

  • E

    enterprise storage

    Enterprise storage is a centralized repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous (and possibly dissimilar) computer systems.

  • F

    FCoE (Fibre Channel over Ethernet)

    FCoE (Fibre Channel over Ethernet) is a storage protocol that enable Fibre Channel communications to run directly over Ethernet. FCoE makes it possible to converges storage and IP protocol traffic onto a single cable transport and interface.

  • Fibre Channel

    Fibre Channel is a technology for transmitting data between computer devices at data rates of up to 4 Gbps (and 10 Gbps in the near future). (Continued...)

  • Fibre Channel adapter

    A Fibre Channel (FC) adapter is a hardware component that provides connectivity from a server to a storage area network (SAN).

  • Fibre Channel Arbitrated Loop (FC-AL)

    A Fibre Channel Arbitrated Loop (FC-AL) is a high-speed Fibre Channel (FC) topology that can connect up to 126 ports on one controller using a one-way loop or hub design.

  • Fibre Channel Industry Association (FCIA)

    The Fibre Channel Industry Association (FCIA) is an international organization whose goal is to help its members promote Fibre Channel (FC) technology.

  • Fibre Channel over IP (FCIP or FC/IP)

    Fibre Channel over IP (FCIP or FC/IP, also known as Fibre Channel tunneling or storage tunneling) is an Internet Protocol (IP)-based storage networking technology developed by the Internet Engineering Task Force (IETF).

  • FICON (Fiber Connectivity)

    FICON (for Fiber Connectivity) is a high-speed input/output (I/O) interface for mainframe computer connections to storage devices.

  • H

    hard zoning

    Hard zoning is used to allocate resources and control access in a storage-area network (SAN).

  • host bus adapter (HBA)

    A host bus adapter (HBA) provides physical connectivity and input/output between a server and a network and/or storage device.

  • I

    iFCP (Internet Fibre Channel Protocol)

    iFCP (Internet Fibre Channel Protocol) is an emerging standard for extending Fibre Channel storage networks across the Internet.

  • IP storage

    IP storage is a general term for several approaches to using the Internet Protocol (IP) in a storage area network (SAN) usually over Gigabit Ethernet.
