Restrictive nonsense seems common in the server space unfortunately. HPe do similar things. IIRC they disabled certain features if you used non-HPe ‘approved’ hard drives.
Dell also does this with their EMC storage arrays, it’s meant to push you towards their pro services. You are supposed to tell the array to order drives for you from pro services and someone from some nameless MSP contracted with dell installs it for you at a 10x markup.
Are there even any good server vendors? Dell, HPE and Lenovo do their lock-in shit. Supermicro's BMC is pretty bad. xFusion is totally-not-Huawei-I-pwomise. There's a few more that come to mind but all of them are niches like HPC and don't really do sales on a small scale.
