Configuring array and virtual disk
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 data is
recovered 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 only after you have created the virtual disk or you have
configured network HDD, see “Managing Network HDD” on page 134. Our
device provides two ways for creating the virtual disk, including one-touch
configuration and manual configuration. The following flow chart shows the
process of creating virtual disk.
