I have an old VTrak E Class rig that has held the test of time pretty well.  I currently have it connected to an Xserve over FibreChannel cables.  I am preparing to retire the XServe.  I'd like to keep the VTrak where it is but connect it to either my Mac Pro via Thunderbolt 2 or a Mac Mini (Thunderbolt 3).  I suspect this would be very trivial using a SanLink2 FC to Thunderbolt if I was willing to string a long Thunderbolt cable.  I am not.  My experience with the Corning long (10m) Thunderbolt cables are that they are trash.  So I am wondering if I can go Thunderbolt to Ethernet to Fibre Channel or some such in order to connect my Mac to the Vtrak.  Is this possible?  If so, what interim devices do I need?
