Storage Technology Definitions

  • I

    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.

  • IP SAN (Internet Protocol storage area network)

    An IP SAN is a dedicated storage area network (SAN) that allows multiple servers to access pools of shared block storage devices using storage protocols that depend on the Internet Engineering Taskforce standard Internet Protocol suite.

  • 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.

  • IPI (Intelligent Peripheral Interface)

    IPI (Intelligent Peripheral Interface) is a high-bandwidth interface between a computer and a hard disk or a tape device.

  • iSCSI (Internet Small Computer System Interface)

    The iSCSI transport layer protocol allows the SCSI command to be sent over LANs, WANs and the Internet. Learn about its role in iSCSI SANs and virtualization.

  • iSCSI initiator

    An iSCSI initiator is software or hardware that enables a host computer to transmit data to an iSCSI-based storage array through a network adapter over a TCP-based IP network.

  • iSCSI switch (Internet Small Computer System Interface switch)

    An iSCSI switch is an appliance that processes and channels data between an iSCSI initiator and target on a storage device.

  • J

    Jaz drive

    A Jaz drive is a small, portable hard disk drive used primarily for backing up and archiving personal computer files.

  • JBOD (just a bunch of disks or just a bunch of drives)

    JBOD ("just a bunch of disks") refers to a computer's hard disks that haven't been configured according to the RAID system.

  • K

    Kibi, mebi, gibi, tebi, pebi, and all that

    Kibi, mebi, gibi, tebi, pebi, and exbi are binary prefix multipliers that, in 1998, were approved as a standard by the International Electrotechnical Commission (IEC) in an effort to eliminate the confusion that sometimes occurs between decimal (power-of-10) and binary (power-of-2) numeration terms.

  • Kilo, mega, giga, tera, peta, exa, zetta and all that

    Kilo, mega, giga, tera, peta, exa, zetta are among the list of prefixes used to denote the quantity of something, such as a byte or bit in computing and telecommunications.

  • kilobyte (KB or Kbyte*)

    As a measure of computer memory or storage, a kilobyte (KB or Kbyte*) is approximately a thousand bytes (actually, 2 to the 10th power, or decimal 1,024 bytes).

  • Kryder's Law

    Kryder's Law describes the rate at which former Seagate CTO Mark Kryder predicted disk drive density would grow.
