[0002] A multi-node server can be, but is not limited to, integrating multiple independent computing nodes into the same system. Each node occupies a corresponding storage device (e.g., hard disk). Different nodes of a multi-node server share a backplane, and the backplane and each node establish communication and control through a middle backplane. For example, a four-node server has an 8-port backplane. Each node on the server can establish communication with the 8-port backplane through the middle backplane. Each node occupies 2 hard disks in the 8-port backplane, and each node and the corresponding hard disk are independent of each other in data management and communication.

[0039] Through the above steps, the first controller can generate a control signal matching the connection state according to the detected connection state of the server device, and control the power supply line corresponding to the storage device through the control signal to realize automatic control of powering on and off the storage device. In this way, when the connection state of the server device changes, the storage device is automatically controlled to power on or off according to the actual connection state of the server device, thereby solving the problem of low control efficiency of the storage device and achieving the effect of improving the control efficiency of the storage device.

[0040] In the technical solution provided in the above step S202, the server device may include but is not limited to a separate server device, or a server device deployed with multiple nodes. For example, multiple sets of processing devices are deployed in the server device, and each set of processing devices may include but is not limited to corresponding CPU (Central Processing Unit) and GPU (Graphics Processing Unit) and other devices. In this case, a complete set of processing devices may be but is not limited to being used as a node.

[0041] Optionally, in this embodiment, the server device may, but is not limited to, perform read operations or write operations on data stored in the storage device through the first controller, etc. For example, the storage device may, but is not limited to, include a hard disk, or a raid, etc. This application does not impose any restrictions on this.

[0045] Optionally, in this embodiment, the second controller may be, but is not limited to, used to control a power supply line corresponding to the storage device. For example, the second controller may be, but is not limited to, include a TPS259260 chip.

[0046] Figure 4 is a schematic diagram of an optional control architecture of a storage device according to an embodiment of the present application Figure 2 ,like Figure 4 As shown, it can be but not limited to taking the example that server nodes 0 to server nodes 3 are deployed on the server device, the first controller is deployed on the mid-backplane S2, and slots Slot0-1, Slot2-3, Slot4-5 and Slot6-7 are deployed on the hard disk backplane, where one node is equivalent to one server device, and one slot is used to connect one storage device (for example, a hard disk).

[0047] The S1 server node can, but is not limited to, establish communication with an 8-port HDD (Hard Disk Drive) backplane through the midplane, and each node occupies 2 hard disks. The 8-port backplane and the midplane Midplane establish communication through relevant data lines, wherein the midplane Midplane integrates a first controller (for example, a CPLD programmable controller), and establishes a logical relationship in advance in the programmable controller CPLD, that is, after the node Node0 is shut down, a trigger signal is given to the midplane Midplane, and the midplane sends a signal (equivalent to the second control signal) to the 8-port backplane through the logical relationship set by the programmable control 4-node 8-port backplane server CPLD, and issues a power-off instruction to the hard disk on the 8-port backplane slot0-1 associated with the node Node0; conversely, after the midplane Midplane receives the power-on signal of the node Node0, the midplane sends a signal (equivalent to the first control signal) to the 8-port backplane through the logical relationship set by the programmable control 4-node 8-port backplane server CPLD, and issues a power-on instruction to the 8-port backplane slot0-1 hard disk associated with the node Node0 according to the CPLD logic setting.

[0048] The S3 backplane can be designed to obtain power from the S2 middle backplane. When any server node is powered on, the S2 middle backplane will be powered, so that the S3 backplane can be powered. However, which hard disk slots of the S3 backplane are powered on is subject to the power-on and power-off status of each node. For example, a logical relationship as shown in Table 1 can be established in the CPLD programmable controller.

[0050]

[0051] In an exemplary embodiment, a control device may be deployed on the target server device but is not limited to being connected to the first controller, the control device being used to control the target server device to be turned on and off, and the target connection state of the target server device in the server device is detected by: receiving an initial control signal generated by the target server device in response to a target control operation performed on the control device, wherein the target control operation is used to control the target server device to be turned on or turned off; and detecting the target connection state according to the initial control signal.

[0052] Optionally, in this embodiment, the control device may be, but is not limited to, a device for controlling the target server device to be turned on and off, such as controlling the target server device to be turned on or controlling the target server device to be turned off.

[0053] As an optional example, a switching device may be but is not limited to being deployed on the target server device, the switching device is connected to the control device, and the switching device is used to switch the server device to be controlled. The target server device is deployed with a switching device, the switching device is connected to the control device, and the switching device is used to switch the server device to be controlled. The method comprises: detecting a target switching operation performed on the switching device, and switching the server device to be controlled to the target server device in response to the target switching operation.

[0054] Figure 5 is a schematic diagram of a switching device and a control device deployed on an optional server device according to an embodiment of the present application, combined with Figure 4 and Figure 5 As shown, each node of the S1 server can switch different nodes N0 / N1 / N2 / N3 through the server front control panel to perform independent power on and off control of the nodes. That is, after pressing the Node switch key (equivalent to the switching device), it will switch between nodes N0 / N1 / N2 / N3. When switching to N0, pressing the "power on and off key" (equivalent to the control device) can turn on and off the node N0.

[0055] In this way, the user can switch the server device to be controlled by triggering the switching device, which reduces the complexity of the process of switching the server device and improves the efficiency of the user switching the server device to be controlled.

[0056] In an exemplary embodiment, the target connection status can be detected based on, but not limited to, the initial control signal: when the initial control signal is at a high level, the target connection status is determined to indicate that the connection between the target server device and the first controller is normal; when the initial control signal is at a low level, the target connection status is determined to indicate that the connection between the target server device and the first controller is abnormal.

[0057] Optionally, in this embodiment, the low level and the high level may include but are not limited to logic levels. As an optional example, the low level may be but are not limited to being used to indicate that the voltage is less than a voltage threshold, and the high level may be but are not limited to being used to indicate that the voltage is greater than or equal to the voltage threshold. For example, the high level may be identified by 1 and the low level may be identified by 0.

[0058] Optionally, in this embodiment, a normal connection between the target server device and the first controller may include but is not limited to the server device being powered on or operating normally, etc.; an abnormal connection between the target server device and the first controller may include but is not limited to the server device being powered off or the server device being disassembled, etc.

[0059] Through the embodiments of the present application, when the server device is turned off, a low-level signal will be automatically triggered, and when the server device is turned on or operating normally, a high-level signal will be automatically triggered. In this way, the first controller can automatically detect the connection status between the server device and the first controller by receiving the initial control signal triggered by the server device, thereby improving the timeliness of detecting the connection status between the server device and the first controller.

[0060] In the technical solution provided in the above step S204, different server devices may have but are not limited to corresponding storage devices.

[0063] Optionally, in this embodiment, the first controller stores server devices and storage devices with corresponding relationships. When the first controller receives an initial control signal sent by the target server device, it can, but is not limited to, search for the target storage device corresponding to the target server device from the server devices and storage devices with corresponding relationships.

[0064] In this way, the first controller generates a corresponding control signal for controlling the line corresponding to the storage device based on the initial control signal generated by the received target server device, thereby reducing the complexity of controlling the power supply line corresponding to the storage device and improving the efficiency of controlling the power supply line corresponding to the storage device.

[0065] In the technical solution provided in the above step S206, the second controller can be but is not limited to being used to control the target power supply circuit to output the target power supply voltage required by the target storage device or stop outputting the power supply voltage according to the target control signal. As an optional example, the target power supply voltage can be but is not limited to including the rated voltage of the target storage device or the voltage required for the actual operation of the target storage device.

[0066] As an optional example, after sending the target control signal to the second controller on the target power supply line, the method further includes: detecting an update connection status of the target server device in the server device, wherein the update connection status is used to indicate an update connection status between the target server device and the first controller; generating an update control signal matching the update connection status according to the update connection status, wherein the update control signal is used to adjust the power supply status of the target power supply line corresponding to the target storage device to match the update connection status; and sending the update control signal to the second controller on the target power supply line, wherein the second controller on the target power supply line is used to control the target power supply line according to the update control signal.

[0067] In this way, after the server device is shut down, if the server device is restarted, in this case, the power supply voltage output by the power supply line corresponding to the server device will be automatically controlled, and the corresponding storage device will be automatically controlled to be powered on and off according to the connection status of the server device, thereby improving the control efficiency of the storage device.

[0068] In an exemplary embodiment, a signal pin may be deployed on the second controller but is not limited to being connected to the first controller, and the target control signal is sent to the second controller on the target power supply line: when the target connection state is used to indicate that the connection between the target server device and the first controller is normal, a high-level first control signal is sent to the signal pin; when the target connection state is used to indicate that the connection between the target server device and the first controller is abnormal, a low-level second control signal is sent to the signal pin; wherein the target control signal includes the first control signal and the second control signal.

[0077] In order to better understand the control process of the control method of the storage device in the embodiment of the present application, the control process of the control method of the storage device in the embodiment of the present application is explained and illustrated in combination with optional embodiments below, which can be applicable to but not limited to the embodiment of the present application.

[0078] The explanation may be, but is not limited to, that the first controller includes a CPLD, the storage device includes a hard disk, and the second controller includes a TPS25926 chip. Figure 6 is a schematic diagram of an optional power supply circuit according to an embodiment of the present application, combined with Figure 4 , Figure 6As shown, the power supply of each storage device needs to have a controlled EFUSE circuit. Taking the TPS25926 chip setting EFUSE control circuit as an example, the TPS25926 chip is used to control the power supply of the hard disk on the backplane. After receiving the control signal, it can turn on or off the power supply to the hard disk.

[0079] The EFUSE circuit is equipped with a TPS25926 chip. The TPS25926 chip is equipped with pins "EN / UVLO" (equivalent to a signal pin) and out 0 to out3 (out 0 to out3 are equivalent to output pins). The TPS25926 chip is also equipped with VIN1 pin 3 to VIN pin 3, which are connected to a power supply (e.g., P12V_Out1). The TPS25926 chip is also equipped with an ILIM pin, which may include, but is not limited to, a current limiting pin for limiting current. For example, the current threshold may be limited to, but is not limited to, (0.7+3*R / 100000)=3.85A.

[0080] It should be noted that Figure 6 The device also includes capacitors C621, C623, and C625, resistors R286, R287, and R375. The functions of capacitors C621, C623, and C625, resistors R286, R287, and R375 are the same as those in the related art, and will not be described in detail in this application.

[0081] The hard disk backplane is usually designed to be powered by 12V and 5V. When the node Node0 is powered off, a low-level signal is transmitted to the CPLD. After the CPLD makes a judgment, it sends a low-level signal "HDD_12V_EN <0> ” (equivalent to the second control signal) transmits information to pin “EN / UVLO” (equivalent to the signal pin) to disable the Out pin (equivalent to the output pin), that is, the TPS25926 chip controls the EFUSE circuit not to output voltage, thereby realizing the power-off of the corresponding backplane slot, that is, turning off the corresponding HDD0 power supply.

[0082] When the node Node0 is powered on, a high-level signal is transmitted to the CPLD, and the CPLD sends a high-level signal "HDD_12V_EN" after judgment. <0> ” (equivalent to the first control signal) transmits information to pin “EN / UVLO” (equivalent to the signal pin), enabling the Out pin (equivalent to the output pin), that is, the TPS25926 chip controls the EFUSE circuit to output the power supply voltage required by the hard disk, thereby realizing the power-on of the corresponding backplane slot, that is, realizing the corresponding HDD0 power supply.

[0083] For example, taking the server node Node0 as an example, when the user needs to perform maintenance operations on Node0, the user can, but is not limited to, select Node0 as the node to be controlled through the "Node switch key" on the server front control panel, and then trigger the "power key" to shut down Node0, and automatically send a low-level signal to the CPLD deployed in the midplane. The CPLD sends a low-level signal to the second controller (for example, TPS25926 chip) in the power supply line corresponding to Node0. After the second controller (for example, TPS25926 chip) receives the low-level signal sent by the CPLD, it stops outputting voltage, so that the hard disk corresponding to Node0 is automatically powered off.

[0084] When the maintenance work is completed, Node0 is restarted, and Node0 automatically triggers a high-level signal. The CPLD receives the high-level signal and automatically sends a high-level signal to the CPLD deployed in the midplane. The CPLD sends a high-level signal to the second controller (for example, TPS25926 chip) in the power supply line corresponding to Node0. After the second controller (for example, TPS25926 chip) receives the high-level signal sent by the CPLD, it outputs the required voltage, so that the hard disk corresponding to Node0 is automatically powered on. The whole process is automated and efficient, ensuring the stable operation of the server and the safe maintenance of the hard disk.

[0085] Through the embodiment of the present application, when a multi-node server performs maintenance on a certain node, the hard disk of the node being maintained is automatically powered off, saving unnecessary power consumption, and at the same time putting the hard disk in a stopped working state, reducing the hard disk life decay. In addition, it is beneficial to the maintenance of the multi-node server, whether it is reducing a node in a fully configured node or adding a node in a non-fully configured node, the corresponding node hard disk can be automatically powered on and off with the node, without affecting the services of other nodes.
