The last time I actually tried anything with Redhat I was trying to build a file server with RHEL v6.8 on a circa 2014 Dell. Absolutely zero support for the drive controllers. It felt like installing Linux in the mid-1990’s. I gave up in frustration after two days and gave Ubuntu 16.04 LTS a try. As far as I know, that server’s still chugging away with 98 terabytes of storage at that office.
