  • software-defined storage

    Software-defined storage (SDS) is a data storage approach in which all the programming that controls storage-related tasks exists solely in software external to the applicable storage systems.  Definition

  • paging

    Paging is a method of writing data to, and reading it from, secondary storage for use in primary storage, also known as main memory. Paging plays a role in memory management for a computer's OS (operating system).  Definition

  • Multipath I/O (MPIO)

    Multipath I/O (MPIO) is a Microsoft framework designed to mitigate the effects of a host bus adapter (HBA) failure by providing an alternate data path between storage network devices.  Definition

  • data center bridging (DCB)

    Data center bridging (DCB) describes the four technology enhancements to existing 802.1 bridge specifications standards being developed by the IEEE 802.1 Data Center Bridging Task Group.  Definition

  • 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.  Definition

  • virtual LUN or thin LUN

    A virtual LUN (virtual logical unit number) is a representation of a storage area that is not tied to any physical storage allocation. Virtual LUNs are used in thin provisioning (also known as virtual provisioning) for storage area network (SAN) mana...  Definition

  • logical unit number (LUN)

    A logical unit number (LUN) is a unique identifier used to differentiate separate devices (each of which is a logical unit) as addressed by a SCSI, iSCSI or Fibre Channel (FC) protocol.  Definition

  • LUN masking

    LUN masking is a further constraint added to zoning, subdividing access to the port so that only LUNs authorized to access a specific server can access the corresponding port.  Definition

  • virtual storage area network (VSAN)

    A virtual storage area network (VSAN) is a logical partition in a storage area network (SAN). VSANs allow traffic to be isolated within specific portions of a storage area network.  Definition

  • 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.  Definition
