  • virtual address - A virtual address is a binary number in virtual memory that enables a process to use a location in primary storage (also called main memory) independently of other processes, and to use more space than actually exists in primary storage.
  • virtual floppy disk - A virtual floppy disk is an alternative to the traditional floppy that exists as a file rather than a physical medium.
  • 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 NAS - Virtual NAS is a virtual machine (VM) that acts as a file server for network-attached storage (NAS).
  • virtual provisioning - Virtual provisioning is a term used by vendors, such as EMC, to describe a process of efficiently provisioning space in storage area networks (SAN).
  • virtual server backup - Virtual server backup is the copying of data stored on a virtual server to guard against data loss.
  • virtual server farm - A virtual server farm is a networking environment that employs multiple application and infrastructure servers running on two or more physical servers using a server virtualization program such as VMware or Microsoft Virtual Server.
  • virtual storage - Virtual storage is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.
  • virtual storage appliance (VSA) - A virtual storage appliance (VSA) is a storage controller that runs on a virtual machine(VM) to create shared storage without the cost of additional hardware.
  • virtual tape - Virtual tape is an archival storage technology that makes it possible to save data as if it were being stored on tape although it may actually be stored on hard disk or on another storage medium.
  • Virtuozzo - Virtuozzo is a software application for enterprise server virtualization that allows an administrator to create virtual environments on a host computer at the operating system (OS) layer.
  • VMware backup - VMware backup is the copying of data on a virtual machine (VM) in a VMware environment to prevent data loss.
  • volume manager - A volume manager is software within an operating system (OS) that controls capacity allocation for storage arrays.
  • VSAM (Virtual Storage Access Method ) - VSAM (Virtual Storage Access Method ) is a file management system for IBM's larger operating systems, including its primary mainframe operating system, MVS, now called OS/390.
  • vSphere Replication - VSphere Replication is a feature of vSphere 5.
  • vStorage API - A vStorage API is an application program interface (API) from VMware that enables third-party storage and backup vendors to integrate their products with VMware’s vSphere server virtualization platform.
  • vStorage API for Multipathing (VAMP) - vStorage API for Multipathing (VAMP) is a set of application program interfaces (APIs) from VMware that help to control I/O path selection in a host to storage devices.
  • vStorage APIs for Array Integration (VAAI) - vStorage API for Array Integration (VAAI) is an application program interface (API) framework from VMware that enables certain storage tasks, such as thin provisioning, to be offloaded from the VMware server virtualization hardware to the storage array.
  • vStorage APIs for Storage Awareness (VASA) - vStorage APIs for Storage Awareness (VASA) is a set of application program interfaces (APIs), released with VMware’s vSphere 5, that enables vSphere vCenter to recognize the capabilities of storage arrays that support the API.
  • What is cloud backup and how does it work? - Cloud backup, also known as online backup or remote backup, is a strategy for backing up data that involves sending a copy of the data over a proprietary or public network to an off-site server and storage system.
  • Windows File System (WinFS) - The Windows File System (WFS) is Microsoft's new storage system for its upcoming SQL server release.
  • Windows Server Failover Clustering (WSFC) - Windows Server Failover Clustering (WSFC) is a feature of the Windows Server platform for improving the high availability (HA) of applications and services.
  • Windows Storage Server 2012 - Microsoft Windows Storage Server 2012 (WSS 2012) is a platform for network-attached storage (NAS ) appliances and iSCSI storage systems.
  • Windows Storage Spaces - Windows Storage Spaces is a feature in Microsoft Windows Server 2012 that is used to virtualize and provision storage.
  • World Wide Name (WWN) - A World Wide Name (WWN) is a unique identifier that is assigned to a manufacturer by the Institute of Electrical and Electronic Engineers (IEEE) and hard-coded into a Fibre Channel (FC) device.
  • XAM (eXtensible Access Method) - XAM (eXtensible Access Method) is a standard that makes it easier to manage fixed content by freeing data from dependencies on location, applications and storage devices.
  • XFS file system - XFS is a 64-bit, highly scalable file system that was developed by Silicon Graphics Inc.
  • yobibyte (YiB) - A yobibyte (YiB) is a unit of measure used to describe data capacity as part of the binary system of measuring computing and storage capacity.
  • Zadara Storage - Zadara Storage provides enterprise level primary and secondary storage-as-a-service (STaaS).
  • Zadara VPSA and ZIOS - Zadara Storage provides block, file or object storage with varying levels of compute and capacity through its ZIOS and VPSA platforms.
  • zebibyte (ZiB) - A zebibyte (ZiB) is a unit used to measure computing and storage capacity.
  • Zerto - Zerto is a storage software vendor that specializes in enterprise-class business continuity and disaster recovery in virtual and cloud environments.
  • ZFS - ZFS is a local file system and logical volume manager created by Sun Microsystems to control the placement, storage and retrieval of data in enterprise computing systems.
