5.2. Is Your Hardware Compatible?
Red Hat Enterprise Linux 7 should be compatible with most hardware in systems that were factory built within the last two years. Hardware compatibility is a particularly important concern if you have an older or custom-built system. Because hardware specifications change almost daily, it is recommended that all systems be checked for compatibility.
The most recent list of supported hardware can be found in the Red Hat Hardware Compatibility List, available online at https://access.redhat.com/ecosystem/search/#/category/Server. Also see Red Hat Enterprise Linux technology capabilities and limits for general information about system requirements.
