It’s a USB-over-network connection, and you use the SX Virtual Link software to connect/disconnect the USB connection. To the computer and device it really looks like a connect/disconnect, so that should be enough to let Drobo sleep without physically pulling the plug.
Of course if you can physically eject and pull the plug, that’s the $0 solution.

I have had very good experience with their support and products. I’m on the third USB device server - it gets better every generation.
