Is hardware compatibility that of RHEL?

Dear all,

I was asking in a previous thread about RAID+SSDs or PCIe SSD. Then I realized the Proxmox kernel is based on that from RHEL. My question is... Does all hardware working on RHEL work on Proxmox?. Should all kernel modules developed for RHEL be compatible with Proxmox?. If not, how can I know what hardware is supported under Proxmox out of the box or through drivers?.

thanks in advance,

Jose
