One central FOG server plus multiple Storage nodes in different locations possible?


  • I’m trying to find out if my idea is possible. I work for a school district and Im gonna implement FOG. My question is if its possible to have the FOG server at a central office location and Storage nodes at each of the campuses (around 17 campuses) spread out in a city. We are all connected together using a telecommunication company routers.

    Lets say I’m in at campus A with storage node A and I image, does the image travel all the way to central office Main FOG? or does the storage node A take care of it?

    You can only capture images to the central server. The storage nodes are deploy only.

    This is the most important point I think. From what @tesparza said so far it sounds as if image capture to storage nodes is wanted.

    @tesparza Your idea will work fine. That is in line with how FOG was designed with a central (master) server and remote storage nodes.

    Now there are a few caveats with this design.

    1. The storage nodes need to be in contact with the central server 100% of the time.
    2. Computers with the fog client installed must be able to talk to the central server continuously.
    3. You can only capture images to the central server. The storage nodes are deploy only.

    In addition to the storage nodes, you will need to install the fog location plugin. This way you can defined storage nodes to a location as well as computers to a location. That way during imaging the computer knows who to talk to.

    During the pxe booting process the remote computer will download iPXE from the storage node, but then it needs to talk to the master node to find out where its storage node is location. Once FOS Linux (engine that clones the system) is up and running it will download the image for whatever storage node the computer is assigned to.
