Storage Technology Definitions

  • G

    global namespace

    Global namespace is a feature that provides a consolidated view into multiple Network File Systems (NFS), Common Internet File Systems (CIFS), network-attached storage (NAS) systems or file servers that are in different physical locations.

  • GlusterFS (Gluster File System)

    GlusterFS (Gluster File System) is an open source distributed file system that can scale out in building-block fashion to store multiple petabytes of data.

  • Google Cloud Storage

    Google Cloud Storage is an enterprise public cloud storage platform that can house large unstructured data sets.

  • green cloud

    Green cloud is a label that describes the potential environmental benefits that information technology services delivered over the Internet can offer society. 

  • green storage

    Green storage is the practice of using a variety of "clean energy" storage methods and products to cut down on a data center's carbon footprint, as well as cost.

  • grid storage

    Grid storage is a general term for any approach to storing data that employs multiple self-contained storage nodes interconnected so that any node can communicate with any other node without the data having to pass through a centralized switch. (Continued...)

  • H

    HA storage (high-availability storage)

    High-availability storage (HA storage) is a storage system that is continuously operational or provides at least 99% uptime.

  • Hadoop as a service (HaaS)

    Hadoop as a service provides organizations with big data analytics capabilities that are deployed and managed through a third party. This lets organizations without in-house expertise use the complicated Hadoop framework to gain insight into their data.

  • hard disk

    A hard disk is part of a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces.

  • hard disk drive (HDD)

    Hard disk drives are a type of physical storage media that use spinning disk platters to store nonsequential data in personal computers and enterprise data centers.

  • hard drive shredder

    A hard drive shredder is a mechanical device that physically destroys old hard drives in such a way that the data they contain cannot be recovered.

  • hard zoning

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

  • hardware RAID (hardware redundant array of independent disk)

    Hardware RAID is a form of RAID where processing is done externally.

  • HD-DVD (high-density DVD)

    HD-DVD (high-density DVD) is an optical digital storage medium with a capacity that far exceeds that of standard DVD media... (Continued)

  • HD-ROM (High-Density - Read Only Memory)

    HD-ROM (High-Density - Read Only Memory) is a high-capacity storage technology developed at Norsam Technologies in conjunction with an IBM research group that enables a disk to store hundreds of times as much information as a CD-ROM. HD-ROM uses a very narrow, finely-focused particle beam (charged gallium ions) to write data.
