@DBCountMan Yes if you are using the location plugin. Using the location plugin you assign the storage node to a location and then when you register the target computer with FOG you assign the target computer to a location. Then when the computer pxe boots it learns who it needs to communicate with. So a storage node would work in this case to spread the load.
One caveat with storage nodes is that they can’t capture images. Only the master node can capture images. Then all storage nodes (including the master node) in the same storage group can deploy the image.
