I know mellanox nic not support split port , but does other brand support this port ?
Today download qlogic ql45xx nic user guide and read ,found something interest :
so question is did this mean we can split a nic to 4 port and use a qsfp-4xsfp dac to connect other four 10G nic in other pc ? if it indeed support then we can use qsfp+-4xsfp+ dac to connect one server with 40g nic and 4 pc with 10g nic without need switch. maybe dream come to true ?
Did anyone know or already tried this ?
