  • I

    I/O blender effect

    The I/O blender effect is a phenomenon in virtualized environments that degrades storage performance.  The I/O blender effect occurs when multiple virtual machines (VMs) all send their input/output (I/O) streams to a hypervisor for processing.

  • I/O contention (input/output contention)

    I/O contention (input/output contention), occurs when virtual machines compete for I/O resources because there is a limited storage bandwidth.

  • I/O virtualization (IOV)

    I/O virtualization (IOV), or input/output virtualization, is technology that uses software to abstract upper-layer protocols from physical connections or physical transports.

  • IBM General Parallel File System (IBM GPFS)

    The IBM General Parallel File System is one of the top file systems used in high-performance computing and the basis for many storage products used in supercomputing.

  • IBM racetrack memory

    Racetrack memory is a type of non-volatile, solid-state nanotech memory being developed by IBM.

  • IBM Spectrum

    IBM ships six storage and management software products that fall under the IBM Spectrum umbrella. They provide services such as capacity, data movement and backup.

  • IDE (Integrated Drive Electronics)

    Integrated Drive Electronics (IDE) refers to the integration of the controller and drive.

  • iFCP (Internet Fibre Channel Protocol)

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

  • illumos

    Illumos is a free, open source operating system (OS) developed as a fork of Unix-based OpenSolaris, the open source community-built derivative of the Solaris OS.

  • InfiniBand

    InfiniBand is an architecture and specification for data flow between processors and I/O devices. The technology is most often used in high-performance computing (HPC) environments... (Continued)

  • information architecture

    In technical writing, information architecture is the set of ideas about how all information in a given context should be treated philosophically and, in a general way, how it should be organized.

  • information life cycle management (ILM)

    Information life cycle management (ILM) is a comprehensive approach to managing the flow of an information system's data and associated metadata from creation and initial storage to the time when it becomes obsolete and is deleted.

  • intelligent switch

    An intelligent switch is a high-level storage area network (SAN) routing switch that provides features such as storage virtualization, quality of service (QoS), remote mirroring, data sharing, protocol conversion, and advanced security.

  • International Standard Recording Code (ISRC)

    The International Standard Recording Code (ISRC) is an international code used to identify sound and audio-visual recordings on compact discs (CDs), music videos, and other media, primarily to ensure royalty payments.

  • Internet Small Computer System Interface (iSCSI) adapter

    An iSCSI adapter is a network interface card that enables the transmission of data between host computers and iSCSI-based storage arrays and typically handles the TCP/IP processing.
