    failover

    Failover is a backup operational mode in which the functions of a system component (such as a processor, server, network, or database, for example) are assumed by secondary system components when the primary component becomes unavailable through either failure or scheduled down time.

  • 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 high-speed networking technology primarily used for transmitting data among data centers, computer servers, switches and storage at data rates of up to 128 Gbps.

  • 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 director (FC director)

    A Fibre Channel (FC) director is a modular, chassis-based, high port-count switch that connects servers, switches and storage in a dedicated FC storage area network (SAN).

  • 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).

  • Fibre Channel port names

    Fibre Channel port names

  • Fibre Channel switch (FC switch)

    A Fibre Channel switch is a networking device that is compatible with the Fibre Channel (FC) protocol and designed for use in a dedicated storage area network (SAN).

  • FICON (Fiber Connectivity)

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

  • file storage

    File storage stores data in a hierarchical structure, usually in a NAS system. The system storing data and the client retrieving data see files and folders in the same format.

  • file synchronization (file sync)

    File synchronization, often used as a form of backup, is the process by which files residing in more than one physical location are kept up to date.

  • file system

    In a computer, a file system -- sometimes written filesystem -- is the way in which files are named and where they are placed logically for storage and retrieval.

  • file virtualization

    File virtualization is the creation of an abstraction layer between file servers and the clients that access those file servers... (Continued)

  • file-area network (FAN)

    A file-area network (FAN) is a set of technologies that facilitate file sharing and data management over a network.

  • FLAPE

    FLAPE (flash plus tape) is an approach to tiered storage that allows administrators to archive data as soon as it is written.

  • flash cache appliance

    A NAND flash cache appliance is a dedicated network appliance that resides between the hosts and underlying storage arrays.

  • flash controller (flash memory controller)

    A flash controller is the part of solid-state flash memory that communicates with the host device and manages the flash file system directory.

  • flash file system

    Flash file systems are designed specifically for memory devices. A well-designed flash device and flash file system ensure flash-based capabilities are used efficiently.

  • flash memory

    Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks.

  • flash memory card

    Flash storage memory cards use nonvolatile semiconductor memory to store pictures, audio and video data on portable and remote devices.

  • flash storage

    Flash storage is any type of drive, repository or system that uses flash memory to keep data for an extended period of time.

  • flash-based solid state drive (SSD)

    A flash solid state drive (SSD)  is a non-volatile storage device that stores persistent data in flash memory. 

  • floating gate transistor (FGT)

    A floating gate transistor (FGT) is a complementary metal-oxide semiconductor (CMOS) technology capable of holding an electrical charge in a memory device that is used to store data.

  • FPM DRAM (Fast Page Mode DRAM)

    Prior to newer forms of dynamic random access memory (DRAM), FPM DRAM (Fast Page Mode DRAM) was the most common kind of DRAM in personal computers.

  • FRAM (ferroelectric RAM)

    FRAM (ferroelectric RAM) is random access memory that combines the fast read and write access of dynamic RAM (DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory).

  • FreeNAS Project

    The FreeNAS storage operating system is compatible with most major protocols and storage hardware and provides file sharing in a NAS environment.

  • fresh out of the box (FOB)

    Fresh out of the box (FOB) is a term used in solid state storage (SSS) to describe a flash memory device that has experienced few or no program/erase (P/E) cycles since the device was manufactured.
