I'm trying to connect two server racks and I remember back in the day we would use 110 cross connect punch downs for this. Nowadays, I'm wondering if I could just use patch cables with a passthrough patch panel instead. I can't use fiber because the two networks are disconnected, and running new lines also isn't an option. Any thoughts or suggestions?

You're right that 110 or 66 blocks were used in the past, especially for voice. But nowadays, using patch cables is the norm, especially with newer Ethernet standards. You can definitely go ahead and order your patch cables even if you can't use fiber. VLANs could have been an option too, but if that's off the table, sticking with patch cables is a solid plan!
There are a few options: you could manage downtime to redo the setup, or just use a lot of patch cables. It might not be the cleanest solution, but effective with proper cable management. Also, if you can, implement VLANs to help manage traffic better down the line!
I set up something like this years ago and ran individual cables to each punchdown. It worked fine, but I wouldn’t usually recommend it since it could affect performance with untwisted sections. Your idea should work, but just keep in mind it might not be the most efficient way.
I've done something similar before. Just use patch panels that connect Rack A to Rack B directly with short patch cables. I’d recommend keeping it neat with good cable management if you go this route.
Cross connects are mainly for non-data lines. It's generally not supported to extend Ethernet runs this way, as it can cause issues with data integrity. Better to stick to modern methods!
Yeah, a neat setup is always better. I did the same with short cables to minimize clutter and it worked great!
