Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing storage devices. In some implementations, a memory controller receives a logical write request over a logical interface that the memory controller provides for accessing a non-volatile storage device. The logical write request indicates a logical address at which to write data to the non-volatile storage device. In response to receiving the logical write request, the memory controller sends a write request event to a host system. The memory controller receives a physical write command from the host system over a physical interface that the memory controller provides for accessing the non-volatile storage device. In response to receiving the physical write command, the memory controller stores the data in the non-volatile storage device according to the physical write command.

Claim (Index 21):
A method performed by one or more processing devices, the method comprising:\n storing, in memory of a first data storage device, a logical-to-physical mapping that indicates a mapping of logical addresses to physical addresses of the first data storage device; as data is migrated from a second data storage device to the first data storage device, storing, in the memory of the first data storage device, values indicating logical addresses for which the first data storage device does not store valid data; receiving, by the first data storage device, write commands from a host system that instruct copying of data from the second data storage device to the first data storage device; before the data of the second data storage device is fully migrated to the first data storage device, receiving, by the first data storage device, a read request from a guest system that requests data corresponding to a logical address indicated by the read request; and determining, by the first data storage device and based on the values stored in memory of the first data storage device, whether the first data storage device stores the data corresponding to the logical address indicated by the read request.
