Hi Neil!
Thank you for your quick reply.
Yes as mentioned the Raid is already connected to the Mac mini over fibre and is being used at this moment as standard drive that is being shared over SMB. The Mac mini itself is a Mac mini 2018 mounted in a xMac Server with the DuoMode Echo III Module from Sonnet. From my knowledge the Mac mini does have 10GB ethernet card.
Regarding to a 10GB switch, we (the editors) have access to ether a UniFi Switch XG 6 PoE or the UniFi Switch XG 16. Most likely the XG 6 PoE Switch (10Gb Ethernet).
The Mac mini is the Server Room, the edit stations are approx 19 and 50 feet apart from the Server Room. All rooms are networked with a Category 7 ethernet.
Thank you
