Commodity hardware – GlusterFS runs on pretty much anything

From Advanced RISC Machines (ARM) on a Raspberry Pi to any variety of x86 hardware, Gluster merely requires local storage used as a brick, which lays the foundation storage for volumes. There is no need for dedicated hardware or specialized storage controllers.

In its most basic configuration, a single disk formatted as XFS can be used with a single node. While not the best configuration, it allows for further growth by adding more bricks or more nodes.
