2. Logical disk - Wikipedia

   en.wikipedia.org/wiki/Logical_disk

   A logical disk, logical volume or virtual disk (VD [1] or vdisk [2] for short) is a virtual device that provides an area of usable storage capacity on one or more physical disk drive(s) in a computer system. The disk is described as logical or virtual because it does not actually exist as a single physical entity in its own right. The goal of ...

3. Logical volume management - Wikipedia

   en.wikipedia.org/wiki/Logical_volume_management

   Linux Logical Volume Manager (LVM) v1. Most volume-manager implementations share the same basic design. They start with physical volumes (PVs), which can be either hard disks, hard disk partitions, or Logical Unit Numbers (LUNs) of an external storage device.

4. Logical Disk Manager - Wikipedia

   en.wikipedia.org/wiki/Logical_Disk_Manager

   The MMC-based Disk Management snap-in (diskmgmt.msc) hosts the Logical Disk Manager. On Windows 8 and Windows Server 2012, Microsoft deprecated LDM in favor of Storage Spaces. [1] Logical Disk Manager enables disk volumes to be dynamic, in contrast to the standard basic volume format. Basic volumes and dynamic volumes differ in their ability to ...

5. Volume (computing) - Wikipedia

   en.wikipedia.org/wiki/Volume_(computing)

   In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface.

6. Logical unit number - Wikipedia

   en.wikipedia.org/wiki/Logical_unit_number

   Labels or serial numbers stored in a logical unit's storage volume often serve to identify the logical unit. However, the LUN is the only way for an initiator to address a command to a particular logical unit, so initiators often create, via a discovery process, a mapping table of LUN to other identifiers.

7. Logical Volume Manager (Linux) - Wikipedia

   en.wikipedia.org/wiki/Logical_Volume_Manager_(Linux)

   Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing. Managing large hard disk farms by allowing disks to be added and replaced without downtime or service disruption, in combination with hot swapping.
