I've been a long time Debian user but now I'm working with Red Hat and I'm a bit lost. I just installed a fresh install of CentOS 5.5 on a new Dell server. Dell provides a current Red Hat 5.5 driver for mpt2sas. How do I install this driver?

The Dell instructions are not that helpful. They explain an RPM Install and a DKMS Install - what's the difference between the two?

Thanks in advance.

I would say the RPM would install the DKMS really..

Unpack the driver package : tar -xvzf <driver_package>

Then CD into the dir it was extracted to and rpm -Uvh *.rpm

And all will be well :)

RPM is the basic package management system. DKMS is Dynamic Kernel Module Support. The two are not mutually exclusive, you can have an RPM of a DKMS module.

If you have a straight RPM of a driver, it will have to match the specific version of the kernel you are running. What DKMS allows you to do, is install a module that will automatically be rebuilt if the kernel changes. So I would recommend following the instructions for that.
