Multi-Device Storage System with Hosted Services on Peer Storage Devices

A computer-implemented method for execution by a storage device, comprising:

• managing a remotely addressable memory;
• communicating with a plurality of peer storage devices over an interconnect fabric;
• storing a plurality of hosted services for accessing local memory resources and local compute resources for data management operations for the plurality of peer storage devices;
• receiving a service host request from a service requester;
• identifying a requested hosted service from the service host request;
• executing the requested hosted service using the remotely addressable memory;
• and
• returning a status message to the service requester in response to the requested host service being completed.

A storage device, comprising:

• at least one storage medium;
• a remotely addressable buffer memory;
• means for communicating with a plurality of peer storage devices over an interconnect fabric;
• means for storing a plurality of hosted services for accessing local memory resources and local compute resources for data management operations for the plurality of peer storage devices;
• means for receiving a service host request from a service requester;
• means for identifying a requested hosted service from the service host request;
• and
• means for executing the requested hosted service using the remotely addressable buffer memory.

A storage device, comprising:

• at least one storage medium;
• a fabric interface configured to communicate with a plurality of peer storage devices over an interconnect fabric between the fabric interface and the plurality of peer storage devices;
• a logical mapping memory including:
• storage device media logical mapping information for the at least one storage medium, wherein the storage device media logical mapping information is configured in continuous logical blocks with a media block size equal to a page programming size of the at least one storage medium;
• and
• host logical mapping information for at least one of the plurality of peer storage devices, wherein the host logical mapping information is configured in host logical blocks with a host block size smaller than the media block size;
• a service request handler configured to identify a requested hosted service from a service host request received through the fabric interface;
• and
• a plurality of hosted services configured to access the logical mapping memory for data operations for the plurality of peer storage devices, wherein the service host request initiates at least one of the plurality of hosted services.
