Storage Technology Definitions

  • E

    eMMC (embedded MultiMediaCard)

    An embedded MultiMediaCard (eMMC) is a small storage device made up of NAND flash memory and a simple storage controller.

  • enhanced CD (E-CD)

    Enhanced CD (E-CD) is a compact disc (CD) format that enables discs to be played on either a CD player or a multimedia-capable device, such as a CD-i player, or a DVD-ROM, or CD-ROM drive, where added material can be displayed.

  • enterprise cloud storage

    Enterprise cloud storage is public cloud storage purchased for a large organization. Enterprise cloud storage can be contrasted with consumer cloud storage, which is often free or purchased at a low price for an individual user's needs.

  • enterprise MLC (eMLC)

    Enterprise MLC (eMLC) is a type of MLC flash that has been enhanced to accommodate more write cycles than consumer-grade MLC flash offers.

  • enterprise SSD (enterprise solid-state drive)

    An enterprise SSD (also known as an enterprise solid-state drive or enterprise solid-state disk) stores data persistently or caches data temporarily in nonvolatile memory and generally provides higher performance and greater endurance than consumer or client SSDs.

  • enterprise storage

    Enterprise storage is a centralized repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous (and possibly dissimilar) computer systems.

  • erasure coding

    Erasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations or storage media.

  • exabyte (EB)

    An exabyte (EB) is a large unit of computer data storage, two to the sixtieth power bytes.

  • Express Bay

    Express Bay is an externally accessible storage slot that is designed to accept a high-performance PCI Express (PCIe) solid-state drive (SSD),

  • external storage

    External storage is all addressable data storage that is not currently in the computer's main storage or memory.

  • F

    failover

    Failover is a backup operational mode in which the functions of a system component (such as a processor, server, network, or database, for example) are assumed by secondary system components when the primary component becomes unavailable through either failure or scheduled down time.

  • fat provisioning (FP)

    Fat provisioning (FP) is the conventional storage provisioning model, in which space is allocated beyond current needs, in anticipation of growing need and increased data complexity... (Continued)

  • FCoE (Fibre Channel over Ethernet)

    FCoE (Fibre Channel over Ethernet) is a storage protocol that enable Fibre Channel communications to run directly over Ethernet. FCoE makes it possible to converges storage and IP protocol traffic onto a single cable transport and interface.

  • Fibre Channel

    Fibre Channel is a technology for transmitting data between computer devices at data rates of up to 4 Gbps (and 10 Gbps in the near future). (Continued...)

  • Fibre Channel adapter

    A Fibre Channel (FC) adapter is a hardware component that provides connectivity from a server to a storage area network (SAN).
