The school district I used to work for, we had about 15 servers on 15 different subnets. All of them were tied together to a central server, and we used the location plugin. I’m the guy that set all of that up.
If you have 17 sites - one lonely little storage node won’t cut it. In the summer when all the technicians are imaging everything non-stop, you will fall behind because it won’t keep up with the pace you need. You need to run a storage node at each site and tie them all to a central server - and use the location plugin.
