Hardware Requirements

An Unraid Server runs entirely from RAM, minimizing writes to the Flash device. However, it is also used to store vital system configuration data and must remain installed in your server during operation.

Device Requirements

  • 1 Must contain a unique GUID (Globally Unique Identifier)
  • 2 Minimum 2GB in size, maximum 32GB in size

If you have any questions about a USB drive, please ask our helpful community or see this helpful video.

Additional Requirements

The minimum hardware requirements to install Unraid OS 6 for data storage usage are:

  1. A 64-bit capable processor, 1.0 GHz or better
  2. At least 4GB of RAM
  3. Linux hardware driver support for storage, Ethernet, and USB controllers
  4. Two hard disk drives to ensure data protection with a parity disk

Additional requirements apply when adding applications or virtual machines.

To run many applications, your system should have at least a quad-core CPU (2.4 GHz or faster) and 4-8GB of RAM. As you load more applications, you’ll need to add additional resources.

To run VMs, you must have hardware-assisted virtualization (HVM) support on your processor/motherboard (Intel VT-x / AMD-V). To assign host-based PCI devices, like graphics and sound, to your VMs, your CPU and motherboard must also support IOMMU (Intel VT-d / AMD-Vi).

Each of the three types of VMs you can create using Unraid OS 6, have slightly different requirements for virtualization support.
