10.2 Disk Array

A disk array is a data storage virtualization technology that combines multiple physical disk drives
into a single logical unit. Also known as a "RAID", an array stores data over multiple HDDs 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", based the redundancy and
performance required.

10.2.1 Create a Disk Array

The video recorder supports software-based disk arrays. Enable the RAID function as required. Two
ways are available for creating an array: one-touch configuration and manual configuration.
One-Touch Creation
One-touch configuration creates the disk array. By default, the array type created by one-touch
configuration is RAID 5.
Before You Start
Install at least 3 HDDs. If more than 10 HDDs are installed, 2 arrays will be created. To maintain
reliability and stability running of the HDDs, it is recommended to use of enterprise-level HDDs of
the same model and capacity.
Steps
1. Go to Storage → Advanced .
2. Check Enable RAID.
3. Click Apply and reboot the device to have settings take effect.
