Storage system and method for dynamic selection of a host interface

A method comprising:

• performing the following in a host:
• establishing communication with a storage system comprising a memory, wherein a first host interface is implemented by the storage system upon establishing communication;
• sending, to the storage system via the first host interface, a command to prepare for a switch from the first host interface to a second host interface, wherein the storage system loads firmware to implement the second host interface in response to receiving the command to prepare for the switch;
• receiving an acknowledgement from the storage system that the storage system is prepared for the switch;
• sending, to the storage system via the first host interface, a command to switch from the first host interface to the second host interface;
• and
• receiving an acknowledgement from the storage system that the storage system has implemented the second host interface.

A storage system comprising:

• a memory;
• means for implementing a first host interface upon establishing communication with a host;
• means for loading firmware to implement a second host interface in response to receiving, from the host, a command to prepare for a switch from the first host interface to the second host interface;
• means for sending an acknowledgement to the host that the storage system is prepared for the switch;
• and
• means for implementing the second host interface in response to receiving, from the host, a command to switch from the first host interface to the second host interface.
