Claim Text:
1. A method comprising: performing speed negotiation and transmitter training independently on each of the ports at one end of four parallel connected Fibre Channel links, each port including an independent PHY; determining, after speed negotiation and transmitter training, if the ports at one end of each of the four parallel connected Fibre Channel links are capable of operating as parallel lanes; determining, after speed negotiation and transmitter training, if each of the ports at one end of the four parallel connected Fibre Channel links has indicated capability of 128 Gbps operation; determining, after speed negotiation and transmitter training, if each of the four parallel connected Fibre Channel links has independently negotiated for 32 Gbps operation; and configuring each of the ports at one end of the four parallel connected Fibre Channel links for 128 Gbps operation upon determining that the ports at one end of each of the four parallel connected Fibre Channel links are capable of operating as parallel lanes, that each of the ports at one end of each of the four parallel connected Fibre Channel links has indicated capability of 128 Gbps operation and that each of the four parallel connected Fibre Channel links has independently negotiated for 32 Gbps operation.
