In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods.

Next, a storage device provided by the embodiment of the present application is introduced in detail. Fig. 1 is a schematic structural diagram of a storage device provided by an embodiment of the present application, the storage device includes a BMC 11, a storage device frame 12, a controller tray 14 for fixing a controller 13, and the storage device frame 12 and the controller tray respectively 14 connected to the electric locking part 15, and the position detector 16 connected to the controller tray 14.

In the embodiment of the present application, in order to prevent the controller 13 from being accidentally removed during the firmware upgrade stage, the controller 13 may be connected to the storage device frame 12 through the electric locking component 15 . Considering that in practical applications, it is more difficult to directly connect the controller 13 with the electric locking part 15, so the controller 13 can be fixed on the controller tray 14, thereby connecting the electric locking part 15 and the controller tray 14 connections.

The shape and size of the controller tray 14 can be set according to the shape and size of the controller 13 , and the shape and size of the controller tray 14 are not specifically limited here.

The controller 13 is fixed on the controller tray 14 , and when the controller 13 needs to be removed from the storage device frame 12 , the controller tray 14 will be directly removed from the storage device frame 12 . In practical applications, in order to detect whether there is a behavior of moving out of the controller 13, the controller tray 14 can be connected with the position detector 16, and the position detector 16 can be used to detect whether the controller tray 14 is moved. By the time the controller tray 14 is moved, motion information can be fed back to the BMC 11 .

The BMC11 is respectively connected with the position detector 16 and the electric locking part 15, and is used to control the electric locking part 15 to connect the controller tray 14 with the storage device frame if the motion information fed back by the position detector 16 is received when the firmware upgrade is performed. 12 lock.

In the embodiment of the present application, the electric locking component 15 can be of various types, and the electric locking component 15 can include a reduction motor 151 provided with a gear and a rack 152 arranged inside the storage device frame 12; the reduction motor 151 can be Set on the controller tray 14, the rack 152 can be flattened on the inside of the storage device frame 12. The length of the rack 152 is limited. The front view of its structure can be seen in FIG. 2 .

In the initial state, the gear of the geared motor 151 and the rack 152 are engaged with each other. When the speed of the geared motor 151 is zero, the geared motor 151 and the storage device frame 12 are in a clamped state. Since the geared motor 151 is arranged on the controller tray 14, so that the controller tray 14 and the storage device frame 12 can be in a locked state.

In practical applications, by controlling the gear of the geared motor 151 to move on the rack 152, the geared motor 151 can be moved out from the rack 152, so that the controller tray 14 can be separated from the storage device frame 12 to achieve removal of the controller tray 14 Purpose. Therefore, whether the controller tray 14 and the storage device frame 12 are clamped depends on whether the gear of the reduction motor 151 moves. Therefore, in the case where the electric locking component 15 includes a geared motor 151 and a rack 152 arranged inside the storage device frame 12, the position detector 16 can be arranged at the rear end of the geared motor 151. The device 16 is used to detect whether the gear of the reduction motor 151 moves.

In the initial state, the gear and the rack 152 are meshed, the reduction motor 151 has no speed, and the gear displacement detected by the position detector 16 is zero. Once the reduction motor 151 has the speed, the gear of the reduction motor 151 starts to move. 16 can feed back the detected motion information to the BMC11.

When the BMC 11 receives the motion information fed back by the position detector 16 , it can know that the gear of the reduction motor 151 is moving, and there is a behavior of moving out of the controller 13 . In the firmware upgrade stage, in order to avoid the failure of the firmware upgrade caused by the removal of the controller 13, at this time, the BMC 11 can transmit a modulation signal for controlling the reverse rotation of the gear motor 151 to the gear motor 151 according to the motion information, so that the controller tray 14 Lock with the storage device frame 12.

The position detector 16 can be an encoder; the encoder is connected to the geared motor 151 . The motion information detected by the position detector 16 may include information such as the moving distance and moving speed of the geared motor 151 . According to the motion information, BMC11 can determine the magnitude of the external force that controls the geared motor 151 to move forward, so that a force in the opposite direction of the same magnitude can be transmitted to the geared motor 151, so that the gear of the geared motor 151 is in a relatively static state, thereby maintaining The gear of the reduction motor 151 and the rack 152 inside the storage device frame 12 are always in a meshing state, so as to achieve the locking effect of the controller tray 14 and the storage device frame 12 .

In the embodiment of the present application, the BMC 11 transmits a force in the opposite direction to the geared motor 151 in the form of a modulated signal. The modulation signal may be a pulse width modulation signal (Pulse Width Modulation, PWM). The manner in which the BMC 11 transmits the modulated signal to the geared motor 151 is a relatively mature technology, and will not be repeated here.

In practical applications, in order to ensure the smooth implementation of the firmware upgrade, it is only necessary to ensure that the controller 13 is not removed during the firmware upgrade stage, and there is no need to monitor and control the movement of the controller 13 in other stages. Therefore, when the firmware upgrade is completed, the BMC 11 does not need to electrically lock the controller tray 14 and the storage device frame 12 again.

Therefore, in the embodiment of the present application, when the BMC 11 completes the firmware upgrade or receives an unlocking instruction, it may stop transmitting the modulation signal to the geared motor 151 .

In practical applications, the firmware upgrade operation can be performed by BMC11 or by other devices.

When the firmware upgrade operation is performed by the BMC11, the BMC11 may directly stop transmitting modulation signals to the geared motor 151 after completing the firmware upgrade task.

When the firmware upgrade operation is performed by other devices, the other devices can feed back an unlock command to the BMC 11 after completing the firmware upgrade task, indicating that the firmware upgrade has been completed, and there is no need to electrically lock the controller tray 14 and the storage device frame 12 again. When the BMC 11 receives the unlock instruction, it may stop transmitting the modulation signal to the geared motor 151 .

Considering that in practical applications, the reduction motor 151 will only be moved by the action of external force, the BMC11 transmits a force of the same size and opposite direction to the reduction motor 151, so that the gear of the reduction motor 151 and the inner side of the storage device frame 12 The rack 152 is always in an engaged state. After the BMC 11 transmits a force in the opposite direction to the geared motor 151, the gear of the geared motor 151 will be in a nearly static state. But once the external force suffered by the reduction motor 151 disappears, if the BMC11 still transmits a force in the opposite direction to the reduction motor 151, the gear of the reduction motor 151 will move in the opposite direction, and the position detector 16 will detect the deceleration again at this time. When the gear of the motor 151 moves, the position detector 16 can feed back the displacement information to the BMC 11 again. In this case, it also indicates that the BMC 11 does not need to transmit a modulation signal to the reduction motor 151 . Therefore, in the embodiment of the present application, the unlock command may also be the displacement information that the position detector 16 feeds back to the BMC 11 when it detects that the gear of the reduction motor 151 is moving.

In the firmware upgrade stage, according to the magnitude of the external force on the geared motor 151, a modulation signal is transmitted to the geared motor 151 to ensure that the gear of the geared motor 151 and the rack on the storage device frame 12 are in a meshing state. When the firmware upgrade is completed or the external force on the geared motor 151 disappears, the transmission of modulation signals to the geared motor 151 is stopped in time, effectively avoiding the invalid production work of the BMC11.

In practical applications, in order to ensure that the controller tray 14 is locked with the storage device frame 12, position detectors 16 and deceleration motors 151 can be respectively arranged on both sides of the controller tray 14; Gear racks 152 are provided at positions corresponding to the geared motors 151 .

In the initial state, the gear meshes with the rack. FIG. 3 is a side view of the meshing structure of the gear and the rack of a geared motor provided in an embodiment of the present application. The gear motor 151 is subjected to an external force to cause the gear to move. When the gear moves out of the rack, the controller tray 14 will be separated from the storage device frame 12 . At this time, the controller tray 14 can be moved out of the storage device frame 12 . Taking the straight line where the rack is located as the horizontal line, the gear motor 151 can move forward or backward along the horizontal line under the action of an external force. The moving direction depends on the direction of the external force and is not limited here.

By setting reduction motors 151 on both sides of the controller tray 14, the gears on both sides of the controller tray 14 can be respectively engaged with the racks on the storage device frame 12 through the gears of the reduction motors 151, ensuring that the controller tray in the initial state 14 and the storage device frame 12 can be firmly connected.

In the embodiment of the present application, the electric locking component 15 can also be composed of an electric pin and a groove, in addition to the geared motor 151 and the rack 152 . In a specific implementation, the electric locking component 15 may include an electric latch and a groove provided on the inner side of the storage device frame 12 facing the electric latch; the electric latch is arranged on the side wall of the controller tray 14 .

In practical applications, the positions of the electric latch and the groove can be determined according to the direction in which the controller 13 is moved out of the storage device frame 12 . Wherein, the straight line formed by the electric plug and the groove is perpendicular to the direction in which the controller 13 is moved out of the storage device frame 12 .

Considering that in practical applications, the controller 13 will generally be removed from the storage device frame 12 in a vertical upward direction, so the electric latch can be arranged on the side wall of the controller tray 14 . If the BMC 11 receives the motion information fed back by the position detector 16 when performing firmware upgrade, it will control the electric latch to insert into the groove, so that the controller tray 14 and the storage device frame 12 are locked.

In order to ensure the locking effect between the controller tray 14 and the storage device frame 12, the number of electric latches can be set to be multiple.

In practical applications, in order to ensure the smooth implementation of the firmware upgrade, it is only necessary to ensure that the controller 13 is not removed during the firmware upgrade stage, and there is no need to monitor and control the movement of the controller 13 in other stages. Therefore, when the firmware upgrade is completed, the BMC 11 does not need to electrically lock the controller tray 14 and the storage device frame 12 again.

Therefore, in the embodiment of the present application, the BMC 11 can control the electric latch to move out of the groove when the firmware upgrade is completed or the unlocking command is received.

In practical applications, the firmware upgrade operation can be performed by BMC11 or by other devices.

When BMC11 performs the firmware upgrade operation, BMC11 can directly control the electric bolt to move out of the groove after completing the firmware upgrade task.

When the firmware upgrade operation is performed by other devices, the other devices can feed back an unlock command to the BMC 11 after completing the firmware upgrade task, indicating that the firmware upgrade has been completed, and there is no need to electrically lock the controller tray 14 and the storage device frame 12 again. When BMC11 receives the unlock command, it can control the electric latch to move out of the groove.

In practical applications, BMC11 can control the electric bolt to be inserted into or removed from the groove through the drive circuit. The implementation method belongs to the existing relatively mature technology and will not be repeated here.

In the initial state, the electric slot is in the state of moving out of the groove. In the firmware upgrade stage, if it is detected that the controller tray 14 is moved, the BMC 11 can control the electric latch to be inserted into the groove, so as to ensure that the controller 13 is fixed in the storage device frame 12 to ensure the smooth execution of the firmware upgrade. After the firmware upgrade is completed, there is no need to restrict the movement of the controller 13, so the BMC 11 can control the electric plug to move out of the groove, so that the electric plug returns to its original state.

Considering that in practical applications, the user may not know that the storage device is performing a firmware upgrade operation, so there is an act of removing the controller 13 by mistake. For this situation, an alarm can be set in the storage device; BMC11 is connected to the alarm, and is used to trigger the alarm to give an alarm prompt if it receives the motion information fed back by the position detector when performing firmware upgrade.

There can be multiple ways of alarm prompting, such as voice alarm or sound and light alarm.

The alarm prompt through the alarm can facilitate the user to know in time that the current storage device is performing a firmware upgrade operation, and does not support the operation of removing the controller 13, thereby preventing the user from removing the controller 13 by mistake.

It can be seen from the above technical solution that the storage device includes a BMC, a storage device frame, a controller tray for fixing the controller, an electric locking component connected to the storage device frame and the controller tray, and a position connected to the controller tray. Detector. The controller is fixed on the controller tray, and when the controller needs to be removed from the storage device frame, the controller tray will be directly removed from the storage device frame. The position detector can be used to detect whether the controller tray is moving. When the controller tray is detected to move, it indicates that there is a behavior of moving the controller. At this time, the position detector can feed back the motion information to the BMC. The BMC is respectively connected to the position detector and the electric locking component, and is used to control the electric locking component to lock the controller tray and the storage device frame if the motion information fed back by the position detector is received during firmware upgrade. In this technical solution, by fixing the controller on the controller tray and connecting the controller tray with the storage device frame through an electric locking component, the BMC can directly control the The electric locking part locks the controller tray and the storage device frame, thereby preventing the user from removing the storage controller by mistake and ensuring the smooth completion of the firmware upgrade.
