TrueNAS can run on a variety of hardware configurations. However, the system requirements for installing TrueNAS CORE may vary depending on the hardware configuration and your system’s intended use. These requirements include:

  • Processor: You’ll need a 2-Core Intel 64-Bit or AMD x86_64 processor.
  • RAM: You’ll need at least 8 GB of RAM, but more is better for larger deployments or more demanding workloads.
  • Storage: Installing TrueNAS requires 16 GB solid-state drives (SSDs) or at least two hard drives of equal size for a single storage pool.
  • Network: An ethernet cord is necessary since it doesn’t support a wireless connection.
  • DVD or USB stick: Since CDs don’t work, a DVD or USB stick of at least 1 GB is necessary for TrueNAS installation media.

How To Install TrueNAS?

Installing TrueNAS CORE can seem challenging at first. However, we’ve prepared this guide and explained every step of the process in simple terms. It will help you successfully install TrueNAS with little to no effort. The process consists of the following steps:

Step 1Add the Installer to a Device or Create a Bootable Drive

To start the installation process, you first need to get a copy of the installer and put it on a device you’ve chosen to set up TrueNAS. You can do that in two ways:

  1. Add it to a device.
  2. Create a bootable drive.

Adding the installer to a device refers to downloading the TrueNAS CORE installer program and copying it onto a USB stick or a DVD. Then, insert the device into your computer.

Creating a bootable drive means using a tool to copy the installer program onto a USB stick and then configuring the device to be bootable. The second method is usually faster and more convenient than adding the installer manually.

Step 2Reboot the System and Choose the Install Device as the Boot Drive

After you complete the first step, reboot the system.

The following menu shows the list of drives you can use for the setup. Select the boot device, not the storage disk. If you’re unsure which of the listed is the boot device, look at the size of the disks. The boot device is usually smaller than storage disks, so navigate to that one using the arrow keys and hit Space.

The warning window will appear. Press OK and Yes to proceed.

Step 3Restart to Start the Installation

The next step is to restart the device to start the TrueNAS CORE setup. The changes you make while setting up TrueNAS won’t apply until the system restarts.

Thus, restarting is necessary because it will apply all the changes you’ve made during the installation process, and the system will start with the newly installed operating system and software components.

Step 4Go Through the Installation

Once you’ve restarted the system, go through the installation and configuration of TrueNAS.

Now you need to boot TrueNAS CORE in either UEFI or BIOS. The system will choose between the two according to your firmware settings. If not, know that BIOS suits older hardware, while UEFI is often better for newer hardware. Also, the choice will depend on the software requirements and operating system.
