What does' Supports up to 8 split ports' mean for ConnectX-8 SuperNIC?

Hi,

According to the ConnectX-8 SuperNIC data manual, it supports two 400G Ethernet ports. Does “Supports up to 8 split ports” mean that each 400G port can be split into four 100G physical ports, totaling eight 100G physical Ethernet split ports?

Thanks,

yes. you would need the correct fanout fiber as well as the correct qsfp28 transceivers

Hi, following to my check, yes, it’s supported.

Thanks,

Yes, that’s correct. Each 400G port on the ConnectX-8 can be split into four 100G physical ports, so with two 400G ports, you get up to eight 100G split ports in total.

I remember coming across an article called How NVIDIA ConnectX-8 SuperNIC Became a Revolutionary NIC?—it explains this pretty well if you’re interested.
