Abstract

An object-based storage system comprising a host system capable of executing applications for and with an object-based storage device (OSD). Exemplary configurations include a call interface, a physical layer interface, an object-based storage solid-state device (OSD-SSD), and are further characterized by the presence of a storage processor capable of processing object-based storage device algorithms interleaved with processing of physical storage device management. Embodiments include a storage controller capable of executing recognition, classification and tagging of application files, especially including image, music, and other media. Also disclosed are methods for initializing and configuring an OSD-SSD device.

Claims

1. A system comprising:

a storage apparatus for processing object storage device (OSD) storage commands at the direction of a host-based OSD interface module, further comprising;

a storage physical layer input-output controller interfacing between the storage apparatus and the host;

at least one solid-state non-volatile memory device (SSD);

a storage controller, separate from said storage physical layer input-output controller, configured to process a set of wear-leveling algorithms interleaved with a set of OSD algorithms;

wherein the set of OSD algorithms translates storage commands from the host into one or more storage commands for the at least one solid-state non-volatile memory device (SSD) using a first communication protocol;

initiates a second communication protocol for communication between the host and the at least one solid-state non-volatile memory device (SSD); and

communicates results from execution of the second communication protocol to the host;

wherein an algorithm of the set of OSD algorithms is identified by a code that maps to a remote location where the algorithm resides.

2. The system of claim 1, wherein the storage controller interfaces to at least two instances of an SSD running in RAID mode.

3. The system of claim 1, wherein the storage controller communicates with an expansion port.

4. The system of claim 1, wherein the host system executes code in a partition.

5. The system of claim 4, wherein the host system further comprises an OSD call interface.

6. The system of claim 5, wherein the OSD call interface implements the T10-OSD specification for OSD commands.
