8.2 Disk Array
A disk array is a data storage virtualizaon technology that combines mulple physical disk drives
into a single logical unit. Also known as a "RAID", an array stores data over mulple 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.
8.2.1 Create a Disk Array
The video recorder supports soware-based disk arrays. Enable the RAID funcon as required. Two
ways are available for
creang an array: one-touch conguraon and manual conguraon.
One-Touch
Creaon
One-touch conguraon creates the disk array. By default, the array type created by one-touch
conguraon 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
