Adaptive interface high availability storage device

A device comprising:

• a first storage interface;
• a first remapping logic, connected to the first storage interface;
• an adaptable circuit connected to the first remapping logic;
• a second remapping logic, connected to the adaptable circuit;
• and
• a second storage interface, connected to the second remapping logic,
• the device being configured to operate in a single-port state or in a dual-port state,
• the device being configured:
• in the single-port state, to present a single-port host side storage interface according to a storage protocol at the first storage interface, and
• in the dual-port state, to present a dual-port host side storage interface according to the storage protocol at the first storage interface,
• wherein the first remapping logic comprises:
• a first channel having a common port connected to the first storage interface and
• a second channel having:
• a common port connected to the first storage interface,
• a first selectable port connected to a first port of the adaptable circuit, and
• a second selectable port connected to a second port of the adaptable circuit,
• wherein:
• the first port of the adaptable circuit is a first root port,
• the second port of the adaptable circuit is a second root port, and
• the first root port and the second root port are based on a protocol.
