I'm considering using an OCP NIC port with a 25Gb active optical cable for iDRAC, rather than the dedicated copper management port. Has anyone used a setup like this, and are there drawbacks to watch for?
Would you use a 25Gb AOC for iDRAC instead of copper?

The big tradeoff is the management path. If iDRAC shares an OCP NIC port with production traffic, a problem affecting that NIC or its network path could also affect management access. That takes away some of the separation you get from a dedicated port.
I'd check whether the specific server, NIC, and iDRAC firmware support shared management over that port and cable before planning around it. Also think through what access remains if the NIC or switch path fails.

It may be a reasonable way to avoid a copper run if the hardware supports it. Just don't expect management tasks to suddenly run at 25Gb. Firmware downloads, for example, can still be limited by the connection to the remote site.

Would two 25Gb ports help with that?
