In computer storage, logical volume management or LVM provides a method of allocating space on mass-storage devices that is more flexible than conventional partitioning schemes to store volumes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions into larger virtual partitions that administrators can re-size or move, potentially without interrupting system use.
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the technology and systems involved, or a specialized device built for such functionality.
In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is "back up", whereas the noun and adjective form is "backup". Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time. Backups provide a simple form of disaster recovery; however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server.

The VERITAS File System is an extent-based file system. It was originally developed by VERITAS Software. Through an OEM agreement, VxFS is used as the primary filesystem of the HP-UX operating system. With on-line defragmentation and resize support turned on via license, it is known as OnlineJFS. It is also supported on AIX, Linux, Solaris, OpenSolaris, SINIX/Reliant UNIX, UnixWare and SCO OpenServer. VxFS was originally developed for AT&T's Unix System Laboratories. VxFS is packaged as a part of the Veritas Storage Foundation.
The Veritas Volume Manager is a proprietary logical volume manager from Veritas.
Veritas Storage Foundation (VSF), previously known as Veritas Foundation Suite, is a computer software product made by Veritas Software that combines Veritas Volume Manager (VxVM) and Veritas File System (VxFS) to provide online-storage management. Symantec Corporation developed and maintained VSF until January 29, 2016, at which point Veritas and Symantec separated. The latest product version, 7.0, was re-branded as "Veritas InfoScale 7.0".
Veritas Cluster Server is a high-availability cluster software for Unix, Linux and Microsoft Windows computer systems, created by Veritas Technologies. It provides application cluster capabilities to systems running other applications, including databases, network file sharing, and electronic commerce websites.
A virtual tape library (VTL) is a data storage virtualization technology used typically for backup and recovery purposes. A VTL presents a storage component as tape libraries or tape drives for use with existing backup software.
A NetApp FAS is a computer storage product by NetApp running the ONTAP operating system; the terms ONTAP, AFF, ASA, FAS are often used as synonyms. "Filer" is also used as a synonym although this is not an official name. There are three types of FAS systems: Hybrid, All-Flash, and All SAN Array:
- NetApp proprietary custom-build hardware appliances with HDD or SSD drives called hybrid Fabric-Attached Storage
- NetApp proprietary custom-build hardware appliances with only SSD drives and optimized ONTAP for low latency called ALL-Flash FAS
- All SAN Array build on top of AFF platform, and provide only SAN-based data protocol connectivity.
Veritas Backup Exec is a data protection software product designed for customers with mixed physical and virtual environments, and who are moving to public cloud services. Supported platforms include VMware and Hyper-V virtualization, Windows and Linux operating systems, Amazon S3, Microsoft Azure and Google Cloud Storage, among others. All management and configuration operations are performed with a single user interface. Backup Exec also provides integrated deduplication, replication, and disaster recovery capabilities and helps to manage multiple backup servers or multi-drive tape loaders.
The IBM SAN Volume Controller (SVC) is a block storage virtualization appliance that belongs to the IBM System Storage product family. SVC implements an indirection, or "virtualization", layer in a Fibre Channel storage area network (SAN).
The Logical Disk Manager (LDM) is an implementation of a logical volume manager for Microsoft Windows NT, developed by Microsoft and Veritas Software. It was introduced with the Windows 2000 operating system, and is supported in Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows 8, Windows 10 and Windows 11. The MMC-based Disk Management snap-in hosts the Logical Disk Manager. On Windows 8 and Windows Server 2012, Microsoft deprecated LDM in favor of Storage Spaces.
The IBM Storage product portfolio includes disk, flash, tape, NAS storage products, storage software and services. IBM's approach is to focus on data management.
The Veritas Cluster File System is a cache coherent POSIX compliant shared file system built based upon VERITAS File System. It is distributed with a built-in Cluster Volume Manager (VxCVM) and components of other VERITAS Storage Foundation products - particularly VERITAS Cluster Server, VERITAS File System, and VERITAS Volume Manager. It uses the underlying mechanisms of VERITAS Cluster Server to manage membership and changes in cluster state.
The Sun Fire X4500 data server integrates server and storage technologies. It was announced in July, 2006 and is part of the Sun Fire server line from Sun Microsystems.
Software-defined storage (SDS) is a marketing term for computer data storage software for policy-based provisioning and management of data storage independent of the underlying hardware. Software-defined storage typically includes a form of storage virtualization to separate the storage hardware from the software that manages it. The software enabling a software-defined storage environment may also provide policy management for features such as data deduplication, replication, thin provisioning, snapshots and backup.
Dell Technologies PowerFlex, is a commercial software-defined storage product from Dell Technologies that creates a server-based storage area network (SAN) from local server storage using x86 servers. It converts this direct-attached storage into shared block storage that runs over an IP-based network.
Veritas Technologies LLC. is an American international data management company headquartered in Santa Clara, California. The company has its origins in Tolerant Systems, founded in 1983 and later renamed Veritas Software. It specializes in storage management software including the first commercial journaling file system, VxFS, VxVM, VCS, the personal/small office backup software Backup Exec and the enterprise backup software, NetBackup. Veritas Record Now was an early CD recording software.
ONTAP or Data ONTAP or Clustered Data ONTAP (cDOT) or Data ONTAP 7-Mode is NetApp's proprietary operating system used in storage disk arrays such as NetApp FAS and AFF, ONTAP Select, and Cloud Volumes ONTAP. With the release of version 9.0, NetApp decided to simplify the Data ONTAP name and removed the word "Data" from it, removed the 7-Mode image, therefore, ONTAP 9 is the successor of Clustered Data ONTAP 8.
