10.2 Disk Array
A disk array is a data storage virtualizaon technology that combines mulple physical disk drives
into a single logical unit. Also known as a "RAID", an array stores data over mulple 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 soware-based disk arrays. Enable the RAID funcon as required. Two
ways are available for
creang an array: one-touch conguraon and manual conguraon.
One-Touch
Creaon
One-touch conguraon creates the disk array. By default, the array type created by one-touch
conguraon 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
sengs take eect.
