RAID
Your video is recorded on the hard disks managed by XNR-4200 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.
