Storage Technology Definitions

  • D

    data life cycle management (DLM)

    Data life cycle management (DLM) is a policy-based approach to managing the flow of an information system's data throughout its life cycle: from creation and initial storage to the time when it becomes obsolete and is deleted.

  • data management platform (DMP)

    A data management platform (DMP), also called a unified data management platform (UDMP) is a centralized computing system for collecting, integrating and managing data large data sets from disparate sources.

  • data migration

    Data migration is the process of transferring data between data storage systems, data formats or computer systems.

  • data reduction in primary storage (DRIPS)

    Data reduction in primary storage (DRIPS) is the application of capacity optimization techniques for data that is in active use.

  • data retention

    Data retention, also called records retention, is the continued storage of an organization's data for compliance or business reasons. 

  • data storage

    In a computer, storage is the place where data is held in an electromagnetic or optical form for access by a computer processor.

  • DDR SDRAM (double data rate SDRAM)

    DDR SDRAM (double data rate SDRAM) is synchronous dynamic RAM (SDRAM) that can theoretically improve memory clock speed to at least 200 MHz*. It activates output on both the rising and falling edge of the system clock rather than on just the rising edge, potentially doubling output.

  • deep archive

    A deep archive is a type of data archiving that refers to a storage location for data that will likely never be accessed again, but can't be deleted.

  • defragmenter

    A defragmenter is a software utility that rearranges the fragments or discontiguous parts of each file stored on a computer hard disk so that the small, empty storage spaces adjacent to fragments can be used, effectively creating new storage space and possibly making file access faster.

  • Dell EMC World

    Dell EMC World is an annual event for Dell EMC customers that showcases new and emerging technologies in the virtualization, cloud and data storage market.

  • Dell EqualLogic

    Dell EqualLogic storage-area network arrays provide varying capacities of hard disk drives and solid-state drives using iSCSI and SATA controllers.

  • delta differencing

    Delta differencing is an incremental approach to backup that only backs up blocks that have changed after the first full backup. The differences are recorded in files called deltas.

  • depository

    A depository is a file or set of files in which data is stored for the purpose of safekeeping or identity authentication.

  • digital film

    Digital film is any storage medium (such as a memory card, diskette, or recordable CD) used in a digital camera to capture and store images.

  • DIMM (dual in-line memory module)

    A DIMM (dual in-line memory module) is the standard memory card used in servers and PCs.
