Documented selection limits

Link speed/ports are supported capabilities, not guaranteed application throughput. Supermicro AIOM, SIOM, microLP and proprietary variants are not interchangeable with ordinary PCIe cards. Check exact chassis/slot form factor, lanes, bracket, airflow, power, firmware, OS and approved optics. No transceiver, cable or host compatibility inferred.
