DVR Storing Constructure (VFS2)

DVR series has a peculiar storing constructure, and its features are as follows.

(1)It is possible to connect 2 sets of HDD internally (Internal, ATA Interface) and 63 sets of HDD externally (External, 2 ports of IEEE1394).

(2)All of the connected HDDs is recognized as one virtual disk, and DVR supports upto 4TB.

(3)Hdds are divided into primary disk (connected firstly) and auxillary disk.

ATA(or EIDE) supports two channel interfaces (Primary/Secondary). Each channel can be connected to two devices (Master/Slave, HDD/CD- ROM). However DVR supports 1 channel interface internally and total two HDDs. In order to prevent confusing VFS2 ’s Primary Disk, we will not use the terms (Primary/Secondary).

(4)Primary disk is composed of log partition, normal partition, and alarm partition, and auxillary disk is composed of only normal partition. So if primary disk has some problem, all of the recorded data will be lost.
