Samsung patents method for storage devices to explain their own log data
This patent describes a system where a computer's main controller asks a storage drive for a specific set of instructions on how to read its status logs. The storage device sends these instructions, known as spec data, along with the actual log information so the controller can correctly interpret the drive's state.
In the filing’s own words
A host device and a storage device are provided. A host device includes a controller configured to process log data related to a state of a first storage device by using first spec data, the first spec data including parsing information for each log page identifier; and a communication circuit, wherein the controller is further configured to: transmit a first request for requesting the first spec data to the first storage device through the communication circuit; receive the first spec data from the first storage device through the communication circuit in response to the first request; transmit a second request for requesting first log data to the first storage device through the communication circuit; and receive the first log data from the first storage device through the communication circuit in response to the second request and process the received first log data by using the first spec data.
What exactly they claim (claim 1)
1. A host device comprising: a controller configured to process log data related to a state of a first storage device by using first spec data, the first spec data including parsing information for each log page identifier; and a communication circuit configured to transmit and receive data to and from the first storage device, wherein the controller is further configured to: transmit a first request for requesting the first spec data to the first storage device through the communication circuit; receive the first spec data from the first storage device through the communication circuit in response to the first request; transmit a second request for requesting first log data to the first storage device through the communication circuit; and receive the first log data from the first storage device through the communication circuit in response to the second request and process the received first log data by using the first spec data provided from the first storage device.
