Dynamic configuration of input/output controller access lanes

A method comprising:

• determining a configuration of a first set of at least two of a plurality of lanes to connect to a first device based on a type of the first device;
• determining a second configuration of a second set of at least two of the plurality of lanes to connect to a second device based on a type of the second device;
• based on the configuration, configuring the first set of at least two of the plurality of lanes by use of a multiplexer for connection to the first device;
• and
• based on connection of the second device to at least two of the plurality of lanes and the second configuration, dynamically configuring the second set of at least two of the plurality of lanes according to the second configuration by use of the multiplexer for connection to the second device, wherein
• the first device to communicate with at least two of the plurality of lanes based on a different lane configuration than that of the second device,
• the first device is to communicate in accordance with a first protocol using the first set of at least two of the plurality of lanes,
• the second device is to communicate in accordance with a second protocol using the second set of at least two of the plurality of lanes,
• the first device comprises one or more of:
• a Peripheral Component Interconnect Express (PCIe) controller, an Ethernet controller, and/or a Serial Advanced Technology Attachment (SATA) controller, and
• the second device comprises one or more of:
• a PCIe controller, an Ethernet controller, and/or a SATA controller.
