Ethernet Cable STP vs UTP

I have never seen STP used. Deploying STP is more complex due to the grounding required. Do you expect a lot of electromagnetic interference? Many of the cables in the datacenter will be fiber anway.

I would imagine that modern UTP has no problem to be deployed in a datacenter. Here is an interesting article:

Yes, you need to provide grounding at one or both ends of the cable as discussed here:

How much power do you have in the electrical cables? How close are they?

Here is another paper also:

Who installed that???

Any electrical or data cable installer knows full well data and electrical cables cannot be situated in the same cable cable tray.  Most DC standards I have read have power cables in an exclusive cable tray and bundled data cables are in another tray.
