User Case: Can I Connect 2 QNAP Together?

☞ "I have two NAS units: a Synology and a QNAP. Can I connect them under the same network?"

☞ "QNAP 1 has plex a server on it with content and a bunch of other stuff. QNAP 2 will have content on it also. I need QNAP 1 to see QNAP 2. How to achieve?"

☞ "Machine one is a tvs-951x and the other machine is a tvs-673. The 951 has one eth ports unused and the 673 has two eth ports unused. Can I connect the two through an eth wire going QNAP to QNAP? How can I connect the two or what do you think I may be doing wrong? Network settings? Thanks in advance!"

Why Connect Two QNAP NAS Together?

Connecting two QNAP NAS devices offers numerous advantages, so many people are willing to do. It enables you to consolidate data from multiple locations, ensuring easy access and data sharing across devices. Additionally, connecting NAS devices can get:

  • Expanded Storage Capacity: When multiple NAS devices are linked together, they form a unified storage pool, combining their capacities into one large volume. This ensures abundant space to store a continuously growing amount of data, eliminating concerns about storage shortage.
  • Data Redundancy and Backup: Redundancy and data backup are essential for data management. When two QNAP NAS devices are connected, users can create RAID configurations that provide data redundancy. If a hard drive fails, the data stored on it can be easily reconstructed from the redundant data, preventing any data loss.
  • Enhanced Data Transfer Speed: Connecting two QNAP NAS devices can enhance data transfer speeds by using link aggregation (also known as port trunking). By combining the network bandwidth of both devices, data transfers become faster. This is especially advantageous when dealing with large file transfers or multimedia streaming.

Preparing to Connect Two QNAP NAS Together

Before connecting two QNAP NAS devices, certain preparatory steps need to be taken to ensure a smooth setup process.

1. Compatibility Check: The first step is to ensure that both QNAP NAS devices are compatible with each other for linking. Checking their compatibility can avoid potential issues during the connection process.

2. Network Setup: The NAS devices must be connected to the same network. Setting up a stable network connection ensures seamless communication between the devices.

3. Firmware Update: Updating the firmware of both NAS devices to the latest version is crucial. Firmware updates often include bug fixes and performance enhancements, which are essential for optimal functionality.

4. Data Backup: Before proceeding with the connection, it is essential to back up any critical data on both NAS devices, for example, you can backup QNAP to pCloud. While the process is generally safe, having a backup ensures data integrity in case of unforeseen issues.

3 Common Ways to Connect Two QNAP NAS Together

There are several methods to connect two QNAP NAS devices. The following steps outline the most common approaches:

Option 1: Direct Connection via LAN Cable

This method involves connecting both NAS devices directly using an Ethernet LAN cable. The devices are linked without the need for a network switch or router.

Option 2: Connection through a Network Switch

Using a network switch, multiple NAS devices can be connected simultaneously, offering a more scalable solution for larger setups.

Option 3: Using QNAP's Qsync for Synchronization

QNAP's Qsync feature allows for seamless synchronization of files and folders between multiple NAS devices. It ensures that the most up-to-date versions of files are available on all connected devices.
