Drive Group and Virtual Drive

Drive Group and Virtual Drive

With the increasing traffic volume of modern data centers, more data needs to run on a single server. When a single drive is insufficient to support system services in terms of capacity and security, multiple drives need to be combined to serve as a visible drive for external entities to meet service requirements. A drive group is a group of physical drives combined as a whole for external entities. Drive groups are the basis for virtual drives.

A virtual drive is a continuous data storage unit divided from a drive group. A virtual drive can be considered an independent drive. Thanks to certain configuration, a virtual drive can provide higher capacity, security, and data redundancy than a physical drive.

A virtual drive can be:

  • A complete drive group.
  • Multiple complete drive groups.
  • Part of a drive group.
  • Parts of multiple drive groups (a part is divided from every drive group, and these parts form a virtual drive).

Related conventions:

  • A drive group is usually specified as Drive Group (DG for short).
  • A virtual drive is usually specified as Virtual Drive, Virtual Disk (VD for short), Volume, Array, and Logical Device (LD for short).
