Manually configurable PCIe lane count for PCIe SSD backplane

A rack server system, comprising:

• a processor;
• a PCIe switch configured to provide a PCIe bus connection;
• a chassis housing a backplane;
• and
• the backplane comprising
• a plurality of drive bay connectors, wherein each drive bay connector provides a PCIe link to a storage device;
• a first cable connector configured to route a first pair of PCIe lanes to a first drive bay connector of the plurality of drive bay connectors;
• and
• a second cable connector configured to route a second pair of PCIe lanes to the first drive bay connector, wherein the first pair of PCIe lanes and the second pair of PCIe lanes are consecutively numbered PCIe lanes of the PCIe bus connection, wherein the first drive bay connector provides a two-lane PCIe link established via the first pair of PCIe lanes, wherein the first drive bay connector provides a four-lane PCIe link established via the first pair of PCIe lanes and the second pair of PCIe lanes, wherein the first cable connector is connected to the PCIe bus connection via a first four-lane cable and wherein the second cable connector is connector the PCIe bus connection via a second four-lane cable, wherein the first pair of PCIe lanes is provided via a first four-lane cable and the second pair of PCIe lanes is provided via the second four-lane cable, wherein a third pair of PCIe lanes is routed to a second drive bay connectors of the plurality of drive bays via the first four-lane cable, and wherein the first drive bay connector is associated with a first status indicator if provided with a two-lane PCIe link and is associated with a second status indictor if provided with a four-lane PCIe link.
