Method for controlling storage device
A method for controlling a storage device is provided. The method may include: transmitting an initial command conforming to a first communications protocol and a data payload including a command parameter conforming to a second communications protocol to the storage device; transmitting a setting command conforming to the first communications protocol to the storage device; transmitting a confirmation command conforming to the first communications protocol to the storage device; and according to a data payload corresponding to the confirmation command, confirming whether the initial command, the setting command, and the confirmation command are successfully executed.
1. A method for controlling a storage device, comprising:
transmitting an initial command conforming to a first communications protocol and a data payload comprising a command parameter conforming to a second communications protocol to the storage device;
transmitting a setting command conforming to the first communications protocol to the storage device;
transmitting a confirmation command conforming to the first communications protocol to the storage device; and
according to a data payload corresponding to the confirmation command, confirming whether the initial command, the setting command, and the confirmation command are successfully executed;
wherein the initial command, the setting command and the confirmation command are different commands.
2. The method of claim 1 , wherein the first communications protocol is a small computer system interface protocol.
3. The method of claim 1 , wherein the second communications protocol is a non-volatile memory express protocol.
4. The method of claim 1 , wherein the initial command is a write buffer command.
5. The method of claim 1 , wherein the setting command is a write buffer command or a read buffer command.
6. The method of claim 1 , wherein the confirmation command is a read buffer command.
7. The method of claim 1 , wherein the initial command, the setting command and the confirmation command utilize different buffer identifiers (IDs).
8. The method of claim 1 , wherein the storage device comprises a bridge controller.
9. The method of claim 1 , further comprising:
when the initial command, the setting command and the confirmation command are not successfully executed, triggering an error management procedure.
10. The method of claim 1 , wherein the data payload corresponding to the confirmation command comprises a completion element conforming to the second communications protocol.
11. The method of claim 1 , wherein the data payload comprising the command parameter conforming to the second communications protocol further comprises a queue identifier (ID).
