volume

In storage media managed by Veritas Volume Manager, a virtual disk made up of a portion or portions of one or more physical disks and representing an addressable range of disk blocks. It is used by applications such as file systems or databases.

A file system on a NetApp unified storage device, such as a filer. Each device has a root volume containing its configuration files, and one or more data volumes containing user data.

Enterprise Media Manager (EMM) volumes are logical units of data storage or cleaning capability on media that are assigned media IDs and other attributes, which are recorded in the Enterprise Media Manager (EMM) volume database.

A virtual device configured over raw physical disk devices. Consists of a block and character device.

A VxVM pseudo device that behaves like a physical block storage device or disk, but has an arbitrarily complex and possibly redundant internal geometry. A volume ultimately maps its logical space to the physical space on real disk drives, although what VxVM sees as a physical disk may in turn be a pseudo device created by another driver or by a storage array, such as a LUN.

In storage media managed by Veritas Volume Manager, a virtual disk made up of a portion or portions of one or more physical disks and representing an addressable range of disk blocks. It is used by applications such as file systems or databases.

In an IBM DS6000 or DS8000 array, an addressable unit (LUN) that is created from an extent pool. See also extent pool

In a NetApp unified storage device, a file system holding user data that is accessible through one or more of the access protocols supported by Data ONTAP, including NFS, CIFS, HTTP, WebDAV, FTP, FCP and iSCSI. Each volume depends on its containing aggregate for all of its physical storage—that is, for all storage in the aggregate’s disks and RAID groups. See also aggregate

In storage media managed by VERITAS Volume Manager, a virtual disk made up of a portion or portions of one or more physical disks and representing an addressable range of disk blocks. It is used by applications such as file systems or databases.

A file system on a NetApp unified storage device, such as a filer. Each device has a root volume containing its configuration files, and one or more data volumes containing user data.

In storage media managed by VVM, a virtual disk made up of a portion or portions of one or more physical disks and representing an addressable range of disk blocks. A volume appears to applications, databases, and file systems like a physical disk device, but it does not have the physical limitations of a physical disk device. A volume consists of one or more plexes, each holding a copy of the selected data in the volume. Due to its virtual nature, a volume is not restricted to a particular disk or a specific area of a disk.

See also plex subdisk

A virtual disk or entity that is made up of portions of one or more physical disks.

A volume is a logical entity that is made up of a portion or portions of one or more physical disks. A volume can be formatted with a file system and can be accessed by a drive letter or a mount path. Like disks, volumes can be basic or dynamic.

A logical disk device that appears to applications, databases, and file systems as a physical disk partition. A logical disk can encompass multiple or one to many physical volumes.

A virtual disk which represents an addressable range of disk blocks used by applications such as file systems or databases.

A virtual disk, representing an addressable range of disk blocks used by applications such as file systems or databases. A volume is a collection of from one to 32 plexes.

A volume is a logical entity that is made up of a portion or portions of one or more physical disks. A volume can be formatted with a file system and can be accessed by a drive letter or a mount path. Like disks, volumes can be basic or dynamic.
