A computing system includes: a gateway block configured to generate a modified operation for communicating a request operation issued by a host device to access a storage device; and wherein the gateway block includes: a conversion block configured to generate a converted interface for converting an interaction interface included in the request operation to the interaction interface executable by the storage device, and a translation block, coupled to the conversion block, configured to generate a translated representation for translating an object representation included in the request operation to the object representation utilized in the storage device.
