I have been using the Mellanox OFED on a RHEL server to access NVMe-oF storage using RDMA. They provide source code that I build using the command "./mlnxofedinstall --with-nvmf --add-kernel-support".
Now I am trying to do the same on a server with OL8.3/UEK6. I followed the Oracle instructions for installing the RDMA packages (ref). This method of install offers me no way to specify build options. How do I know if it is built with nvmf and kernel support? Alternatively, is there a way to obtain a tarball of source code and configure it with the desire options?
