That is not really the case in practice;

You can buy a Mellanox 144-Port Modular InfiniBand DDR Switch
(60-Ports enabled) for around 22k EUR or so

the 24 port switches are around 2k EUR

As most people dont need anything like the full 16 Gbit/s bandwidth
you can connect up your 50 ports for about 13/14k EUR
