Abstract: A method disclosed herein includes storing a data heat map in local cache of a non-volatile memory express (NVME) controller associated with an NVME device, configuring an asynchronous event notification command in a submission queue associated with the NVME device, generating a request for data migration notification to host based on the data heat map, and communicating the data migration notification to a host using the asynchronous event notification command.
