9.2 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.
Note
The funcons in this secon are only available for certain models.
9.2.1 Create a Disk Array
The video recorder supports soware-based disk arrays. Enable the RAID funcon as required, and
ensure each HDD capacity is not less than 4 TB. If your device has no more than 16 SATA interfaces,
a disk array can contain no more than 8 HDDs. If your device has 24 SATA interfaces, a disk array
can contain no more than 12 HDDs. Two ways are available for
creang an array: one-touch
conguraon and manual conguraon.
