Section 3 - Configuration
The four RAID configurations are:
Standard: Creates two separate volumes (or one volume if only one hard drive is
present). The second volume will function as a File Server. Each hard
drive has its own volume.
Note:
Only Standard mode can create the Volume2, which is available as a File
(Samba) Server. Use the NVR Search utility to mount the File Server to
your Windows system.
JBOD: Combines both hard drives in a linear fashion which will create one
large volume geared towards maximum available space.
RAID 0: Combines both hard drives in a striped fashion which will create one
large volume geared towards maximum performance.
Note: If one drive fails, all the data will be lost.
RAID 1: Mirrors the hard drives for redundancy. If one hard drive fails, the other
still has all of the data. Replace the failed hard drive and it will re-mirror,
restoring maximum data protection.
The main RAID page has an Auto-Rebuild Configuration that allows you to
enable or disable the Auto-Rebuild feature. Please see the image on page
38. You can also manually rebuild by clicking the Rebuild button in the RAID
Configuration section.
Note: Rebuilding the volume will erase all data on the newly inserted drive.
