Configuring Storage

Overview

NVRs can require a tremendous amount of storage space depending on the number of cameras,

codec, resolution, and frame rates, recording modes, and the duration for which you wish to

preserve video recordings. At the outset of your use of the NVR system, you will need to have

storage configured to record data. From time to time, you may find it necessary to replace or add a

storage device to produce a greater capacity for video storage.

This chapter describes how to configure storage d

evices that are physically connected to the NVR

and storage devices that are networked to the NVR over a TCP/IP connection.

There are two main storage configuration types, b

asic and advanced configuration. Basic

configuration is the default configuration type where all storage devices and cameras are

contained within one storage set. By using advanced storage configuration, you can create

numerous storage sets and assign storage devices and cameras to storage sets as required to

optimize disk performance.

Overview of Storage Sets

A storage set is a group of storage drives. One storage set is set up by default on an NVR. This is

storage set 1. Initially the default storage set has all enabled storage devices, their media folders

and cameras assigned to it, see Figure 5-1 Basic Storage Configuration.

A Media Folder is a location on a device where media can be recorded to. Media stored in these

fold

ers can include video, audio and analytic media. You can only have one media folder per

storage device. You can choose which media folders on devices are to be used for storage.

Video from the cameras assigned to a particular stor

age set will record to the media folders on the

storage devices that are assigned to the same storage set.

You can easily create additional storage sets and configu

re them as required to optimize the disk

performance, as media can be recorded to storage sets in parallel.

Each storage set must have at least one assigned

media folder for storage. You can assign

multiple media folders and cameras to a storage set. It is recommended that you assign no more

than 32 devices or cameras to a particular storage set.

Verifying Storage Devices

The Virtual Disks (aka LUNs or Volumes) may have all been detected by the NVR, but not

necessarily configured for usage by the NVR. Ensure that your devices are listed in the Devices
