Virtual disk is a logical drive defined in disk group. It is recognized as a physical drive by OS. The allowable number of virtual
disks is up to 16 per disk group, or up to 64 per controller.
The figure below shows a sample configuration in which the Internal RAID Controller is connected with three HDDs, creating
one Disk Group. Two RAID5 virtual disks (VD) are defined in the Disk Group.

Parity
The parity means redundant data. A single set of redundant data is created from the data saved in more than one HDD.
The created redundant data is used for data recovery when a HDD is defected.
Hot-Swap
The hot-swap enables a HDD to be removed (or replaced) under system operation.
Hot-Spare
The hot-spare is prepared as an auxiliary HDD substituting for a defected HDD included in a logical drive which is configured
at a redundant RAID level. Detecting a HDD fault, the system disconnects the HDD (or makes it offline) and starts rebuild
using the hot-spare.
