The fact that RHEL 5.7 is listed as a minimum version in the Technical Exception Matrix probably means that HP has tested the older RHEL 5.x versions and found that they don't work.

 

RHEL 5.5 was released at the end of March 2010. At that time, the model DL380p Gen8 did not exist.

 

The DL380p Gen8 might require some CPU or chipset support features that simply did not exist at the time of RHEL 5.5. You might be able to make a customized installation media with the RHEL 5.5 kernel replaced with a RHEL 5.7 kernel, but after that, your installation will not be a true RHEL 5.5. Can you accept that?

 

If you absolutely need to run an older OS release on newer hardware, the standard solution is virtualization: install a supported OS or dedicated virtualization platform (like VMware ESXi) on the hardware, then create a virtual machine and install your legacy OS on it. Of course, adding the virtualization layer will cause some overhead that will limit the application-level performance of the system - can you accept that?

 

Today, if the requirement is to install an application whose prerequisites say "OS version x.y exactly" instead of "OS version x.y or newer", I would recommend virtualization from the beginning.

 

All hardware and all commercial software has a limited life-cycle: if the application vendor certifies one particular OS version only and does not certify newer versions in a timely manner, you can predict that replacing your original server hardware with newer one will eventually be difficult or impossible - unless you isolate the OS environment from the actual hardware by setting up the required OS on a virtual machine.

 

If the application is expected to be particularly long-lived, you might even want to archive a copy of the OS installation media with the application install media, so that both will be available if a reinstallation becomes necessary.
