RAID
Note: This chapter is applicable for 64-Channel NVRs only.
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 to recover data
if one disk fails. Data is distributed across the drives in one of several ways
called "RAID levels", depending on the redundancy and performance level
required. The 64-Channel NVR is capable of realizing Redundant Array of
Independent Disk, supporting RAID0, RAID1, RAID5 and RAID10.
Before you start
Install the HDD(s) using the same enterprise-level HDDs (including model and
capacity) for the array creation and configuration maintaining reliable and stable
running conditions for the disks.
Introduction
The 64-Channel NVR can store the data (such as record, picture, and log
information) in the HDD after you have created the virtual disk or you have
configured network HDD
, see “Managing Network HDD” on page 153. There are
2 ways to create the virtual disk, one-touch configuration and manual
configuration. The following flow chart shows the process of creating array.
