ForumForeign,   You would be able to find the listed controllers in the technical spec sheets for each server specifically. So for the R550 it would be page 8 here, and with the R450, it would be on page 9 here. Now on a side note, and as seen on page 6 of the tech spec, Oracle isn't listed as supported.    Let me know if this helps.      
Hello. I have 2 servers which haven't suitable drivers for Oracle Solaris and OS can't detect any disks. How I can determine all suitable disk controllers for both of servers, which may be, not so new and have suitable drivers?
All suitable HBA/disk controllers
