13.1 Configuring Array

RAID (redundant array of independent disks) is a storage technology that combines
multiple disk drive components into a logical unit. A RAID setup stores data over multiple
hard disk drives to provide enough redundancy so that data can be recovered if one disk
fails. Data is distributed across the drives in one of several ways called "RAID levels",
depending on what level of redundancy and performance is required.
The DVR supports the disk array that is realized by software. You can enable the RAID
function on your demand.
Note:
The GD-RT-AT5016N supports the RAID0, RAID1, RAID5, RAID6 and RAID 10 array
types.
Before you start
Please install the HDD(s) properly and it is recommended to use the same enterprise-level
HDDs (including model and capacity) for array creation and configuration so as to maintain
reliable and stable running of the disks.
Introduction
The DVR can store the data (such as record, picture, log information) in the HDD only after
you have created the array or you have configured network HDD (refer to Chapter14.2
Managing Network HDD). Our device provides two ways for creating array, including
one-touch configuration and manual configuration. The following flow chart shows the
process of creating array.
