VIVOTEK - Built with Reliability

130 - User's Manual

With up to 4 disk drives, you have the following options for conguring storage volumes:

1. Single disk: The single disk conguration provides no fault tolerance. The system stores

video recordings to one or more single disk volumes in a consecutive order.

Storage Volume RAID Levels

Single disks

Disk 0 Disk 1 Disk 2

2. RAID0: A RAID0 volume spreads data blocks of each le across multiple disk drives. The

volume provides no redundancy. RAID0 provides high performance by simultaneously reading

or writing to disk drives, but if a drive fails, all data within is lost. Select at least 2 disks to build

a RAID0 volume.

N/A

Disk 0 Disk 1 Disk 2

3. RAID1: A RAID1 volume provides high fault tolerance by writing the same data blocks

simultaneously to duplicate disks. Select at least 2 disks (or 4 disks) to build a RAID1 volume.

N/A

Disk 0 Disk 1

Each single disk volume contains one disk drive.

By default, the Installation Wizard congures all disk drives into individual single-disk volumes. If

you need to create RAID proteced volumes, delete these single-disk volumes to free them from

the conguration.
