  • soft zoning

    Soft zoning is used to allocate resources and control access in a storage-area network (SAN). 

  • hard zoning

    Hard zoning is used to allocate resources and control access in a storage-area network (SAN). 

  • software-defined storage

    Software-defined storage (SDS) is an approach to data storage in which the programming that controls storage-related tasks is decoupled from the physical storage hardware. Software-defined storage is part of a larger industry trend that includes soft... 

  • 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). 

  • 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. 

  • 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. 

  • 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. 

  • 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... 

  • 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. 

  • 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.
