Storage management and analytics Definitions

  • C

    carrier hotel (colocation center)

    A carrier hotel, also called a colocation center, is a secure physical site or building where data communications media converge and are interconnected... (Continued)

  • Ceph

    Ceph is open source software providing scalable object-, block- and file-based storage under a unified system. Red Hat and SUSE sell commercially supported versions of Ceph.

  • cloud computing maturity model (CCMM)

    A Cloud Computing Maturity Model (CCMM) is a model that defines and analyzes the progress of an organization’s ability to deliver cloud services in key areas such as capabilities, domains, maturity and adoption.

  • Cloud Data Management Interface

    Cloud Data Management Interface (CDMI) is a Storage Networking Industry Association (SNIA) industry standard that defines the interface that applications will use to create, retrieve, update and delete data elements from the cloud.

  • cold storage

    Cold storage is a computer system designed for retaining inactive data, such as information required for regulatory compliance, at low cost and high efficiency.

  • 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...)

  • D

    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.

  • data center migration plan

    A data center migration plan is a strategy created by an organization to migrate a data center with minimal downtime.

  • data deduplication

    Deduplication retains one unique data instance to reduce storage and bandwidth consumed by remote backups, replication and disaster recovery.

  • data destruction

    Data destruction is the process of destroying data stored on tapes, hard disks and other forms of electronic media so that it is completely unreadable and cannot be accessed or used for unauthorized purposes.

  • 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 referred to as a unified data management platform (UDMP), is a centralized system for collecting and analyzing large sets of data originating from disparate sources.

  • 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.
