These cables can be used if you use the Motherboard SATA connections to the server Backplane SATA connections.
Please pay attention that you have a backplane with SATA connections if you order these cables. There are 3 different types in length 50cm, 75cm and 100cm
For optimal airflow a "mix and match" between the different lengths would be optiomal, but a little bit of a hassle. 100 cm always "fits" but you have to squeeze in the extra cable length.
