Configuring Your Server 4-39
Virtual Disk
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 Onboard RAID Controller (LSI
Embedded MegaRAID
) or Optional RAID Controller is connected with three hard disk drives,
creating one Disk Group. Two RAID0 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 hard disk drive.
The created redundant data is used for data recovery when a hard disk drive is defected.
Hot-Swap
The hot-swap enables a hard disk drive to be removed (or replaced) under system operation.
Hot-Spare
The hot-spare is prepared as an auxiliary hard disk drive substituting for a defected hard disk drive
included in a logical drive which is configured at a redundant RAID level. Detecting a hard disk
drive fault, the system disconnects the hard disk drive (or makes it offline) and starts rebuild using
the hot-spare.
