7. The data storage system of claim 1 , wherein the portable code comprises a procedure configured to perform the data processing offload task.

8. The data storage system of claim 1 , wherein the operations performed by the storage controller logic further comprise:

determining a portable code type;

selecting a translator in the translation and execution engine based on the determined portable code type; and

translating the translatable, hardware-agnostic instructions of the portable code using the selected translator.

9. The data storage system of claim 1 , wherein translating and executing the one or more translatable, hardware-agnostic instructions comprises:

determining a present operating condition of the storage device;

determining whether to perform a certain action during translating and executing based on the determined present operating condition of the storage system device; and

translating and executing the one or more translatable, hardware-agnostic instructions in a corresponding manner that optimizes a performance of the data processing offload task by the storage device.

10. The data storage system of claim 1 , wherein the portable code for performing the data processing offload task is stored on the storage device in a precompiled format.

11. The data storage system of claim 1 , wherein the data processing offload task comprises:

performing one of a MapReduce, counting, filtering, compaction, and encryption type of operation on one or more items of the data stored on the non-transitory storage medium.

12. The data storage system of claim 1 , further comprising:

the host device comprising one or more second processors and second logic executable by the one or more second processors to perform operations comprising:

loading the portable code into the storage device for translation and execution by the storage device;

detecting completion of the translation and execution of the portable code by the storage device; and

unloading the portable code from the storage device.

13. A method of operation in a data storage system, comprising:

receiving, by a storage controller logic of a storage device, portable code from a host device configured to be coupled to the storage device, the portable code configured to perform a data processing offload task in the storage device and comprising one or more translatable, hardware-agnostic instructions for processing data stored on a non-transitory storage medium;

translating and executing, by the storage controller logic of the storage device, the one or more translatable, hardware-agnostic instructions of the portable code to perform the data processing offload task in the storage device using a translation and execution engine disposed in the storage controller logic;

sending, by the storage controller logic of the storage device, to the host device an indication of a status of the data processing offload task in the storage device;

determining, by the storage controller logic of the storage device, whether use of the portable code has concluded; and
