Checking The Hardware Requirements - D-Link DNR-322L User Manual

Section 1 - Product Overview

Checking the Hardware Requirements

To use your DNR-322L, you will need at least one hard drive installed. If you plan to use RAID 1, which protects your data
against failure of one hard drive, you will need to install two hard drives.
This section will help you:
• Select the appropriate hard drives
• Determine how much hard disk space you will need
• Ensure your data is protected
• Understand the basic requirements for a router or switch
Selecting hard drives:
You can use hard drives from any manufacturer and with any capacity with your DNR-322L. The D-Link NVR supports standard
3.5" internal SATA drives. If you are unsure, check with your administrator or hard drive retailer/manufacturer to verify that
your hard drives meet this standard
Determining how much hard drive space you need:
In order to protect your data from hard drive failure, your DNR-322L requires more space than what you will use for your data,
sometimes more than double the amount of space required. You should select hard drives that are larger in capacity than
your maximum storage requirements.
Using a Router or Switch:
If you are connecting your NVR to a router or switch, your router or switch should support Gigabit Ethernet
(1000 Mbit/s) for maximum performance. The NVR will auto-negotiate the highest connection speed available to your router
or switch. If you are using port bonding, use a managed switch.
Using an Uninterrupted Power Supply (UPS):
We highly recommend that you use your NVR in conjunction with an Uninterrupted Power Supply (UPS), which will protect
against sudden data loss in power outages surges.
