1. Reasonable design is conducive to wiring

When you develop data center plans, be sure to do so in a "cable-friendly" way. Do not place the rack in a location that is not conducive to cabling. Otherwise, you'll end up with a bunch of wire wrapped around the ground, or dangling cables from the ceiling. Plan carefully to avoid a "disaster" later. And be prepared for future expansion. Additional plumbing, etc., is needed more than you might think.

Second, the jumper wire should not be too long

You have a lot of servers in your rack, each about a foot or so. Don't put three foot patch cords on these servers - it looks bad and is very inefficient. If the lengths between servers are odd, then use interfacing (and testing) techniques to get patch cords that connect nicely to each other. The extra length will give you the problem of cable tangles, kinks, and mess.

3. Don't be stingy on the joints

Don't try to be cheap just because it's cheap, and don't rush to cut the cable. If twisting the cable breaks the connection, you need to do it all over again, and you need to practice. You might think you've saved time and money. But in the end, you're going to have a lot of headaches because you need to fix all the joints.

4. Don’t skip the test

After you've laid the line, test it. Don't take the so-called "star pass" test (a barely pass test). If you don't pass the test 100%, you need to do it again. If the cable still fails the test after doing some tests at the interface, throw it away. Make sure you are using a quality testing tool (and you know exactly how to use that testing tool very well). Such a simple step avoids eventual additional rework.
