i don't understand if the technology 'fibre channel' is something 'software' or something 'hardware' (fibre optics connection) ? Can i create a fibre-channel san using 'some' pieces of existent hardware (like old computer with linux or similar) ? Thanks

At the most basic level it's a signaling protocol. It can run over copper or fiber. So its a combo of hardware and software. Hardware to terminate and transmit traffic and software to interpret that traffic. In my experience (SMB) it works much like a NIC just a different addressing method and certainly different/more expensive hardware.
