More bandwidth to the Apt storage server
Due to a shortage of (actually, "the total absence of") 1Gb ports in the Apt control plane, we hooked dbox2
up with a 10Gb control net connection. However, this uses up one of the 2 10Gb ports available on the node and thus reduces the potential iSCSI bandwidth to nodes.
The options here are either to mount up another HP ProCurve switch that we can hook into the Dell stack at 10Gb, or do what was proposed for the CloudLab storage server (#169 (closed)) and plug in the other 2 x 40Gb card we have and hook the storage server up at 40Gb. The latter again requires that FreeNAS work with the 40Gb Mellanox interface and assumes a 40Gb port we can plug into. The latter should be available as we currently have a 40Gb breakout cable plugged in that provides the existing 10Gb connection.
