Unraid offers incredible ease of use and powerful features like flexible server expansion via mix-and-match drive support, one-click parity setup, powerful docker container management, virtual machine support with hardware passthrough, and much more.
Break the confines of a single OS.
Unraid lets you partition system resources to store and protect data, run any application, and create VMs in isolated environments.
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.
If you have any USB drive questions, ask our helpful community or see this video.
The minimum hardware requirements to install Unraid OS 6 for data storage usage are:
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.
| VM Type | HVM | IOMMU |
|---|---|---|
| Virtual Servers | Required | Not Required |
| Virtual Desktops | Required | Not Required |
| Hybrid VMs | Required | Required |
