SFF-TA-100X based multi-mode protocols solid state devices

A system comprising:

• a computing device;
• and
• a storage device connected to the computing device via a first interface,
• wherein the computing device operates as a controller of the storage device, and
• wherein the computing device is connected to a host device via a second interface,
• wherein the storage device operates in a non-volatile memory express (NVMe) mode and an NVMe over fabrics (NVMe-oF) mode based on a status of a signal at a pin of the second interface based on instructions received from the host device.

A method of selecting operating mode for a storage device, the storage device being connected to a storage device controller via a first interface, wherein the storage device controller is connected to a host device via a second interface, the method comprising:

• determining a status of a signal at a pin of the second interface;
• determining an operating mode of the storage device from among a non-volatile memory express (NVMe) mode and a NVMe over fabrics (NVMe-oF) mode based on the status of the signal at the pin of the second interface;
• and
• determining a status of a dual port pin of the host device to determine if the storage device is operating in a single port mode or a dual port mode.
