If so, you'd have to build a driver disk and maintain your own driver builds for each kernel update. It's not "no hope" exactly, but it would probably take a moderate amount of experience to keep running. I'd be wary of hardware used as far back as CentOS 5, but I don't see driver changes between RHEL 6 and 7 that I'd expect to impact an LSI Megaraid card. The old "megaraid" driver was dropped in RHEL 6, leaving just the megaraid_sas driver in 6 and 7. If you run release 6 on that system (boot a live image), look at "lspci" and "lsmod" output. The latter will tell you what drivers are in use, and should be useful to tracking down support in release 7.
