Storage Volume Raid Levels - Nice Linear LNVR1-08P 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 protected volumes, delete these single-disk volumes to free them
from the configuration�
With up to 2 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�
0
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 two (2) disks (or 4 disks) to build a RAID1
volume�

Each single disk volume contains one disk drive�
