11.1 Configuring Array
Purpose:
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 DS-9600NI-ST&XT and DS-8600NI-ST series NVR support the disk array which is realized by the software,
and RAID0, RAID1, RAID5 and RAID 10 are supported. 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 so as to maintain reliable and stable running of the disks.
Introduction:
The DS-9600NI-ST&XT and DS-8600NI-ST series 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 Chapter12.2
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.
