    Hello, i just found out Storage nodes dont multicast. Very useful for imaging computer labs at a school. Should i stick with storage nodes or do Master nodes at each campus? Can master node communicated with each other? Can multicast ever work with storage nodes?

      @tesparza Your problem is simple and complex at the same time.

      It is true only real fog servers can multicast. Storage nodes can only send images via unicast images.

      If you want to multicast images at each location you will need a full fog server there. The issue is that there will be a separate fog database at each campus, so the computers at campus A will have to register with the FOG server at campus A and not any other campus.

      Now you can configure FOG in a non supported way (don’t get mixed up with the words), in that you have a full fog server at each campus, but you can use the FOG replicator from a master (root) node replicate its images to all of the remote fog server. The only gotcha here is that it will only replicate the raw image files to the remote fog server. You will need to manually export and then image the image definitions from the root fog server to each remote campus fog server via the web ui.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

        @george1421 I think we can survive with unicast. We only image once a year. Will just push applications with client. Thank you. For now storage node will work for us.

          @george1421 said in Storage nodes or Master nodes?:

          Storage nodes can only send images via unicast images.

          What’s the technical reason for this? Just wondering. Like, why can’t it be done? Or, has it simply not been implemented?
