Abstract: Implementations disclosed herein include a storage system including a plurality of storage devices, wherein each of the plurality of storage devices includes compute resources, memory resources, and a storage device controller configured to perform application-specific data management operations using the compute resources and the memory resources of the storage device, and a storage system controller configured to distribute a workload across the plurality of storage devices based on a capability of each of the plurality of storage devices during an IDLE state. The capability of each of the plurality of storage devices may be specifications, current availability, and performance history of each of the plurality of storage devices. In some implementations, each of the plurality of storage devices communicate with each other via a peer-to-peer networking communications protocol (e.g., NVme, NVMof, PCIe, Ethernet, etc.).

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.
