RAID

Your video is recorded on the hard disks managed by GNR-2000 built-in RAID (Redundant

Array of Independent Disks) system. Before staring video recording, it is important that

you have installed the number of hard disks you need.

RAID Introduction

There are configurations by which the video recordings on disks can be recovered even in

case of physical failure of several hard disks; however, while using such secure configurations,

the total available storage space will be smaller compared to less secure configurations.

ACTi Standalone NVR servers support 4 different RAID types (0, 1, 5, 10). Depending on the

number of inserted disks, there will be different RAID options available.

RAID 0

RAID 0 combines multiple hard drives into one larger volume. The data is split

between these disks. Under this configuration every inserted disk will be used for

storing data. No disks are used for data backup purposes. Should one of the

disks be damaged, the recordings on all disks will be lost and are not

recoverable, and the use of all remaining disks will be suspended until the

broken disk has been replaced and the whole RAID configuration has been

reset.
