12 RAID
12.1 Configuring Array
Purpose
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 software disk arrays. You can enable the RAID function on demand.
The DVR supports RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 array types.
Before You Start
Install the HDD(s) properly (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 (e.g., record, picture, log information) in the HDD only after you
have created the array or you have configured network HDD. There are two ways to create
an array, including one-touch configuration and manual configuration. The following flow
chart shows the process of creating an array.
