Storage Technology Definitions

  • C

    CompactFlash card (CF card)

    A CompactFlash card (CF card) is a memory card format developed by SanDisk in 1994 that uses flash memory technology to store data on a very small portable device.

  • compression artifact

    A compression artifact is the fuzz or distortion in a compressed image or sequence of video images.

  • conductive metal-oxide (CMOx) technology

    Conductive metal-oxide (CMOx) technology is a nonvolatile storage technology that works by moving oxygen ions between conductive and insulating metal-oxide layers within a single chip.

  • Content Protection for Removable Media (CPRM)

    Content Protection for Removable Media (CPRM) is a hardware-based technology designed to enforce copy protection restrictions through built-in mechanisms in storage media that would prevent unauthorized file copying.

  • content-addressed storage (CAS)

    Content-addressed storage (CAS) is a method of providing fast access to fixed content (data that is not expected to be updated) by assigning it a permanent place on disk. CAS makes data retrieval straightforward by storing it in such a way that an object cannot be duplicated or modified once it has been stored; thus, its location is unambiguous.

  • continuous data protection (storage convergence)

    Continuous data protection (CDP), also called continuous backup, is a storage system in which all the data in an enterprise is backed up whenever any change is made. (Continued...)

  • converged network adapter (CNA)

    A converged network adapter (CNA) is a single network interface card (NIC) that contains both a Fibre Channel (FC) host bus adapter (HBA) and a TCP/IP Ethernet NIC.

  • copy data

    Copy data is the electronic data that is created as a result of data protection functions like backups, snapshots and disaster recovery.

  • copy data management (CDM)

    Copy data management (CDM) is an approach to reducing storage consumption that involves eliminating the unnecessary duplication of production data.

  • OpenStack Block Storage (Cinder)

    OpenStack Block Storage (Cinder) is open source software designed to create and manage a service that provides persistent data storage to cloud computing applications.

  • D

    D2D2C (disk-to-disk-to-cloud)

    D2D2C (disk-to-disk-to-cloud) is an approach to hybrid cloud backup that involves using local storage for staging data that will eventually be sent to a third-part cloud storage service provider.

  • DASD (direct access storage device)

    Direct access storage device (DASD, pronounced DAZ-dee), is a general term for magnetic disk storage devices. The term has historically been used in the mainframe and minicomputer (mid-range computer) environments.

  • DAT USB drive

    A DAT USB drive is a tape drive with digital audio tape (DAT) that can be plugged into a Universal Serial Bus (USB) connection as a simple and relatively low-cost way to back up data routinely, especially on servers. DAT USB technology is expected to make it easier and more affordable for small and medium-size businesses, as well as for larger enterprise data centers, to perform backup and restore operations.

  • data at rest

    Data at rest is a term that is sometimes used to refer to all data in computer storage while excluding data that is traversing a network or temporarily residing in computer memory to be read or updated.

  • data availability

    Data availability is a term used by some computer storage manufacturers and storage service providers (SSPs) to describe products and services that ensure that data continues to be available at a required level of performance in situations ranging from normal through "disastrous.
