Storage Volume Raid Levels - Vivotek ND9322P User Manual

Storage Volume RAID Levels

IMPORTANT:
By default, the Installation Wizard configures 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 configuration.
With up to 4 disk drives, you have the following options for configuring storage volumes:
1. Single disk: The single disk configuration provides no fault tolerance. The system stores
video recordings to one or more single disk volumes in a consecutive order.
Single disks
Disk 0 Disk 1
2. RAID0: A RAID0 volume spreads data blocks of each file 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.

Disk 0 Disk 1
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.
