Do I need QOS on Nexus switches?

I’m using a pair of Nexus 93180YC’s for a VPC deployment with a new shared storage cluster we purchased.

I’ve gone ahead and setup VPC, all of my layer 2, interfaces, my layer 3 interfaces to FW’s and a few HSRP groups. Everything seems to be working fine.

I know very little about QOS, do I need to configure it on brand new Nexus switches? We basically pulled them out of the box and set them up like I described but didn’t do any QOS configs.

Any advice is appreciated! And if you have resources to learn about Nexus QOS that would be great!

Thanks
