Abstract

According to one general aspect, a device may include a host interface circuit configured to communicate with a host device via a data protocol that employs data messages. The device may include a storage element configured to store data in response to a data message. The host interface circuit may be configured to detect when a tunneling command is embedded within the data message; extract a tunneled message address information from the data message; retrieve, via the tunneled message address information, a tunneled message stored in a memory of the host device; and route the tunneled message to an on-board processor and/or data processing logic. The on-board processor and/or data processing logic may be configured to execute one or more instructions in response to the tunneled message.

First claim

What is claimed is:

1 . A device comprising:
an interface circuit configured to communicate with a host device; a storage element configured to store data based on a data message; the interface circuit further configured to:
determine a command associated with the data message; and
obtain from the host device, a message stored on the host device based on information in the data message.

2 . The device of claim 1 , wherein an operations code field of the data message includes a remote procedure call operations code.

3 . The device of claim 1 , wherein the interface circuit is configured to retrieve the data message from a host memory buffer reserved for the device.

4 . The device of claim 1 , wherein the interface circuit is configured to, based on a successful retrieval of the data message, transmit an interrupt signal to the host device.

5 . The device of claim 1 , wherein the information in the data message comprises a message address information; and
wherein the interface circuit is further configured to: determine the message address information from the data message.

6 . The device of claim 1 , wherein the command is a tunneling command.

7 . The device of claim 1 , wherein the interface circuit is configured to perform data message flow control using a protocol for data messages.

8 . A system comprising:
a host computing device comprising:
a processor configured to:
read and write data from a storage device, and
offload commands to the storage device; and

the storage device comprising:
an interface circuit configured to communicate with the host computing device;
a storage element configured to store data based on a data message;
the interface circuit further configured to:
determine a command associated with the data message; and
obtain, a message stored in a memory of the host computing device based on information in the data message.

9 . The system of claim 8 , wherein an operations code field of the data message includes a remote procedure call operations code.

10 . The system of claim 8 , wherein the interface circuit is configured to retrieve the data message from a host memory buffer reserved for the device.

11 . The system of claim 8 , wherein the interface circuit is configured to, based on a successful retrieval of the data message, transmit an interrupt signal to the host computing device.

12 . The system of claim 8 , wherein the information in the data message comprises a message address information; and
wherein the interface circuit is further configured to: determine the message address information from the data message.

13 . The system of claim 8 , wherein the command is a tunneling command.

14 . The system of claim 8 , wherein the interface circuit is configured to perform data message flow control using a protocol for data messages.

15 . A method to be executed on a device, the method comprising:
determining, by an interface circuit on the device, a command associated with a data message; determining, by the interface circuit, message address information from the data message; and obtaining, from a host device a message stored on the host device, based on information in the data message, wherein the interface circuit is configured to communicate with the host device.

16 . The method of claim 15 , wherein an operations code field of the data message includes a remote procedure call operations code.

17 . The method of claim 15 , wherein the interface circuit is configured to retrieve the data message from a host memory buffer reserved for the device.

18 . The method of claim 15 , wherein the interface circuit is configured to, based on a successful retrieval of the data message, transmit an interrupt signal to the host device.

19 . The method of claim 15 , wherein the information in the data message comprises a message address information; and
wherein the interface circuit is further configured to: determine the message address information from the data message.

20 . The method of claim 15 , wherein the command is a tunneling command.
