A RAID controller is typically transparent to the system. Some vendors supply special drivers and firmware in situations where the controller does not work with open software standards, or to support special features.
You could also ask which mouse works, which keyboard works, which harddrive works, which display adapter works, but to my experience this is not going to get you very far. It will be a lot easier to check a specific model and see what vendor support, if necessary, exists, and check the internet for reviews or problems with the product.
If you have a server, then there are usually certified RAID options that come with the server and the vendor support pages will outline support for Oracle Linux or Red Hat Enterprise Linux (RHEL), which are compatible.
I'm not aware of any useful and up to date lists that show a list of RAID controllers supported on Enterprise Linux. I have also no idea about what RAID interface you need, adapter type and available budget and what you plan to use it for.
check hardware server and RAID controller manual for supported OS instead of checking OEL supported RAID controller list, here i copied for HP DL 380 G7 OS certification matrix, where you can find OEL and OVM supprt list.
