  • pre-configuring a hardware-implemented front-end of a storage device with multiple contexts of respective connections conducted between one or more hosts and the storage device, wherein each context includes one or more operational parameters relating to a respective one of the connections;

    executing in a memory of the storage device, using the hardware-implemented front-end, storage commands that are received in the storage device and are associated with the connections having the pre-configured contexts; and

    upon identifying a storage command associated with a context that is not pre-configured in the hardware-implemented front-end, triggering software of the storage device to configure the context in the hardware-implemented front-end, and then executing the storage command using the hardware-implemented front-end in accordance with the context configured by the software.
