Storage Technology Definitions

  • C

    CD-R shelf life

    CD-R shelf life refers to the length of time that a burned compact disc will remain viable once data has been burned onto it... (Continued)

  • CD-ROM XA (Compact Disc - read-only-memory, extended architecture)

    CD-ROM XA (Compact Disc - read-only-memory, extended architecture) is a modification of CD-ROM that defines two new types of sectors that enable it to read and display data, graphics, video, and audio at the same time.

  • CD-RW (compact disc, rewriteable)

    CD-RW (for compact disc, rewriteable) is a compact disc (CD) format that allows repeated recording on a disc.

  • 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.

  • charge-coupled device (CCD)

    A charge-coupled device (CCD) is a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel (picture element) in the image is converted into an electical charge the intensity of which is related to a color in the color spectrum.

  • CIFS (Common Internet File System)

    CIFS (Common Internet File System) is a protocol that gained popularity around the year 2000, as vendors worked to establish an Internet Protocol-based file-sharing protocol.

  • Cinder (OpenStack Block Storage)

    Cinder is the code name for the open source project to develop OpenStack Block Storage, the block-based storage component of the OpenStack cloud computing platform.

  • clustered file system (CFS)

    Clustered file systems are file systems that run on multiple storage servers and can be accessed and managed as a single system.

  • clustered network-attached storage (clustered NAS)

    A clustered NAS system is a distributed file system that runs concurrently on multiple NAS nodes.

  • COLD (Computer Output to Laser Disk)

    COLD (Computer Output to Laser Disk) is a system for archiving data such as business records and reports to one or more optical disks in a compressed but easily retrievable format.

  • 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.

  • column address strobe

    In computer memory technology, CAS (column address strobe) is a signal sent to a dynamic random access memory (DRAM) that tells it that an associated address is a column address. A data bit in DRAM is stored in a cell located by the intersection of a column address and a row address. A RAS (row address strobe) signal is used to validate the row address.

  • Common Information Model (CIM)

    The Common Information Model (CIM) is a computer industry standard for defining device and application characteristics so that system administrators and management programs will be able to control devices and applications from different manufacturers or sources in the same way.

  • compact disc (CD)

    A compact disc is a portable storage medium that can be used for recording, storing and playing back audio, video and other data in digital form.

  • 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.
