This chapter is applicable for GD-RT-AT5016N.
13.1 Configuring 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 DVR supports the disk array that is realized by software. You can enable the RAID function on
demand.
Note:
The GD-RT-AT5016N supports the RAID0, RAID1, RAID5, RAID6 and RAID 10 array types.
Before you start
Please install the HDD(s) properly and it is recommended to use the same enterprise-level HDDs
(including the model and the capacity) for array creation and configuration so as to maintain the
reliable and stable running of the disks.
Introduction
The DVR can store the data (such as record, picture, log information) in the HDD only after you
have created the array or you have configured a network HDD (refer to
Chapter14.2 Managing
Network HDD
). Our device provides two ways for creating an array, including a one-touch
configuration and a manual configuration. The following flow chart shows the process of creating
an array.
