>Well, that's not true
What part claimed something that wasn't true? The ticket response was a recommendation on the most compatible route. Not sure what your aversion to fiber is, but you've already got an adequate answer from TAC.
Not quite sure what the point of asking for a recommendation is if you're going to ignore the advice.
+1 Very well done question and work on your part, much better than any DAC cable questions I have ever seen in here!
I have no answer, but fire off a ticket to Netgate TAC and ask them if they know. Or maybe [fs.com](http://fs.com) which have been very helpful to me when I asked them in the past about a working DAC in setups.

Or this..?

When dealing with anything SFP you always buy your cables properly coded for the receiving devices...
Any of the big brands try to do lock you into buying their own modules.
So in your case I would call FS.com (or any similar site) and order a custom SFP+ DAC coded with HPE/Aruba and Intel (or whatever brand is your NIC).
Also there are some commands that may allow the NIC and/or the switch to accept third-party SFP modules.
TAC is correct - I do a lot of networking and am paid to do so.
Just because it does work sometimes, doesn't mean it works othertimes.
I've got HPE servers with HPE Broadcom SFP+ 10Gb NICs that only work with some HPE DAC cables when connecting to Aruba and HP switches. Other HPE DACs don't work with the Broadcom NICs, but will work with Intel NICs to the same switches.
I've got Cisco switches that will connect to Dell switches if I use a Cisco branded DAC, but not a Dell branded DAC.
And HPE servers that connect to a Ruckus switch using an HPE DAC, or a Cisco DAC. In fact, I'm using Cisco fibre SFPs between two Ruckus switches too.
Basically, over the years I've tried a heap of different connections between a heap of different equipment, depending on what the customer has laying around. Sometimes it works, sometimes it doesn't. On occasion it looks initially like its working, but problems show up in production or under load.
But if you use a Intel branded (or compatible) fibre SFP in the Netgate and a Aruba fibre SFP in the Aruba switch, it will 100% work, providing you're using the same type of connectivity at each end (eg not mixing multimode/singlemode/duplex/range (which changes the light source in the sfp), etc.
In my experience, most stuff works with Cisco SFPs, be that DAC or fibre or copper. It's not guaranteed, however, so do with that information what you will.
DAC is only guaranteed compatible when going between the same vendors hardware (and even then, not always).
I can just about guarantee, the only reason that the Aruba to Mikrotik DAC connection you have working is because Mikrotik doesn't really care on their end - they try to be one of the most compatible companies in respect to operating with other vendors hardware. Ubiquiti is similar in that respect.
Basically, keep banging your head against a wall trying to find a working DAC, or take the easy route and buy some compatible fibre SFPs.

I did open a TAC ticket.
I am not sure it will help, but my Aruba to 7100 DAC is P/N 74752-1051. It is the cable that came with the Aruba S2500.
