Storage Technology Definitions

  • L

    legacy storage

    Legacy storage is traditional storage hardware that is older and sometimes no longer sold by its vendor.

  • litigation hold (preservation orders or hold orders)

    Litigation hold is a stipulation requiring a company to preserve all data that may relate to a legal action involving the company... (Continued)

  • Load DynamiX

    Load DynamiX is a storage performance testing appliance that can simulate production workloads and virtual desktop infrastructure workloads to determine how a system handles stress before putting that system into production. Appliances support all major storage protocols.

  • logical unit number (LUN)

    A logical unit number (LUN) identifies one or more physical or virtual storage devices to a SCSI initiator in a host server to enable data exchange.

  • LUN management

    LUN management is the process of assigning, provisioning and overseeing logical unit numbers (LUNs) across a storage environment.

  • LUN masking

    LUN masking is a further constraint added to zoning, subdividing access to the port so that only LUNs authorized to access a specific server can access the corresponding port.

  • LUN zoning

    LUN zoning is a method of configuring SAN fabric to match logical unit numbers (LUNs) to the proper servers. As a rule, end devices such as hosts can only see and access storage within their zone. Limiting access in this way improves security and allows bandwidth allocation through assigning particular ports to a zone.

  • M

    magneto-optical drive (MO)

    The magneto-optical (MO) drive is a popular way to back up files on a personal computer.

  • magnetoresistive head technology

    Magnetoresistive (MR) head technology is used in disk drives to allow higher storage densities than the older inductive-head technology.

  • MAID (massive array of idle disks)

    MAID (massive array of idle disks) is a storage technology in which only those disk drives in active use are spinning at any given time...

  • Mammoth

    Mammoth is a magnetic tape and drive system used for computer data storage and archiving.

  • mean time to repair (MTTR)

    Mean time to repair (MTTR) is the average time required to fix a failed component and/or device and return it to production status.

  • megabyte (MB)

    As a measure of computer processor storage and real and virtual memory, a megabyte (abbreviated MB) is 2 to the 20th power bytes, or 1,048,576 bytes in decimal notation.

  • megabytes per second (MBps)

    Megabytes per second (MBps) describes a unit of data transfer to and from a computer storage device.

  • memory

    Memory is the electronic holding place for instructions and data that your computer's microprocessor can reach quickly.
