RAID
This chapter applies to DS-9600NI-I8 NVRs.
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 NVR supports software-based disk array. You can enable the RAID function at your demand.
NOTE:
DS-9600NI-I8 Series NVRs support RAID0, RAID1, RAID5, RAID6, and RAID 10 array types.

Before You Start
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.
13.1.2.
Introduction
The NVR can store the data (such as record, picture, log information) in the HDD only after you have
created the array or you have configured a network HDD (refer to Chapter14.2 Managing Network HDD).
Our device provides two ways for creating an array, including one-touch configuration and manual
configuration. The following flow chart shows the process of creating an array.
