14. RAID Setup
14.1. Configuring an Array
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 NVR supports the disk array that is realised by the software. You can enable the RAID function on your
demand.
Before you start:
Please install the HDD(s) properly and it is recommended to use the same enterprise-level HDDs (including
model and capacity) for array creation and configuration to maintain reliable and stable running of the disks.
Introduction:
The NVR can store the data (such as record, picture, log information) in the HDD only after you have created the
array or you have configured network HDD (refer to Managing Network HDD). Our device provides two ways for
creating array, including one-touch configuration and manual configuration. The following flow chart shows the
process of creating array.
14.2. Enable RAID
Perform the following steps to enable the RAID function. If you do not follow the steps, the disk array cannot be
created.
