Using Patch Cables Between Server Racks: Is a Cross Connect Still Needed?

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!

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.

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.

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!

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!
