Description

Technical Field

[0001] The present application relates to the field of server storage technology, and in particular to a method, apparatus, electronic device, and storage medium for configuring volume management device functions. Background Art

[0002] With the rapid development of cloud computing and big data technologies, the current trend of informatization and intelligence in society is accelerating. Servers, as the core equipment of information systems, need to have high-performance storage to meet different application scenarios. NV Me (Non Volatile Memory Express, non-volatile memory host controller interface specification) solid-state drives have gradually become mainstream storage components with advantages such as low latency and low power consumption.

[0003] Intel's VMD (Volume Management Device) function supports hot upgrade and replacement of NV Me solid state drives through the PCIe (peripheral component interconnect express) bus. Figure 1 As shown in the figure, the currently commonly used VMD configuration method is to add a multiplexer chip so that the BIOS (Basic Input Output System) in the PCH (Platform Controller Hub) can reuse the VPP (Virtual Pin Port) interface to directly access the CPLD (Complex Programmable Logic Device) on the hard drive backplane, thereby obtaining NVMe hard drive presence information. Although this method does not require a second restart and the BIOS and BMC (Baseboard Management Controller) are completely decoupled, when the number of CPUs (Central Processing Units) increases, there will be problems such as an increase in the number of multiplexer chips, a longer traversal time, and a complex PCB (Printed Circuit Board) routing topology.

[0050] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] Example 1

[0052] In one embodiment, Figure 2 As shown, a method for configuring volume management device functions is provided, which is applied to a hard disk storage system. The hard disk storage system includes a mainboard, a hard disk backplane, and a hard disk. The mainboard is provided with a first controller, a second controller, and an arbitrator. The first controller is connected to the hard disk backplane via a first serial bus, the second controller is connected to the hard disk backplane via a second serial bus, the arbitrator is provided on the first serial bus and the second serial bus, and the hard disk is connected to the hard disk backplane via a third serial bus. The method includes:

[0053] In response to detecting a power-on signal of the mainboard, controlling the first controller to generate a first control request, and controlling the second controller to generate a second control request;

[0054] Sending the first control request and the second control request to the arbitrator, and determining bus control rights according to a preset arbitration strategy;

[0055] In response to the first controller obtaining the bus control right, controlling the arbitrator to connect the first controller to the hard disk backplane, and controlling the first controller to obtain volume management device configuration options;

[0056] According to the volume management device configuration option, the first controller is controlled to enable / disable the volume management device function of the third serial bus port.

[0057] Specifically, the first controller is the PCH or the BIOS within the PCH, the second controller is the BMC, the first and second serial buses are I2C (Inter-Integrated Circuit, a serial communication protocol) buses, the third serial bus is a PCIe bus, and the hard drive is an NVMe hard drive. By providing an arbitrator on the first and second serial buses and determining bus control rights for the first and second controllers based on a preset arbitration policy, the accuracy and reliability of data transmission are ensured, simplifying software and hardware design and reducing costs.

[0058] In one embodiment, the arbitration strategy includes a request priority, wherein the priority of the first control request is higher than the priority of the second control request. The first control request and the second control request are sent to the arbitrator, and bus control rights are determined according to a preset arbitration strategy, including:

[0059] controlling the arbitrator to parse the first control request and the second control request to obtain corresponding first level signals and second level signals;

[0060] In response to the first level signal being at a high level and the second level signal being at a low level, determining that the bus control right belongs to the first controller;

[0061] In response to the first level signal being at a low level and the second level signal being at a high level, determining that the bus control right belongs to the second controller;

[0062] In response to the first level signal and the second level signal being both high level signals, it is determined according to the request priority that the bus control right belongs to the first controller.

[0063] Specifically, in response to the first level signal and the second level signal being both low level signals, the first controller and the second controller do not have the bus control right. Based on the level signal of the first control request and the level signal of the second control request, as well as the request priority, the ownership of the bus control right is determined, thereby achieving complete decoupling of the first controller and the second controller.

[0064] In one embodiment, Figure 3 As shown, the method further includes:

[0065] In response to the second controller obtaining the bus control right, controlling the first controller to generate a third control request and sending the third control request to the arbitrator;

[0066] In response to the failure of the third control request, the first controller is controlled to generate a soft reset instruction, and the soft reset instruction is sent to the arbitrator, wherein the soft reset instruction is used to reset the arbitrator.

[0067] Specifically, a soft reset command allows the BIOS to gain bus control between motherboard power-up and the completion of PCIE device initialization. Because this period is short, it does not affect BMC functionality. This ensures independent access to the I2C bus between the BIOS and BMC, achieving decoupling from the BMC.

[0068] In one embodiment, the volume management device configuration options include a volume management device enable option, a volume management device disable option, and a volume management device automatic configuration option. Controlling the first controller to enable / disable the volume management device function of the third serial bus port according to the volume management device configuration options includes:

[0069] In response to the volume management device configuration option being the volume management device automatic configuration option, controlling the first controller to enable a volume management device function of the third serial bus port corresponding to the in-place hard disk;

[0070] In response to the volume management device configuration option being the volume management device enable option, controlling the first controller to enable volume management device functions of the third serial bus port corresponding to the in-place hard disk and the unconnected hard disk;

[0071] In response to the volume management device configuration option being the volume management device disabling option, the first controller is controlled to disable volume management device functions of the third serial bus port corresponding to the in-place hard disk and the unconnected hard disk.

[0072] In one embodiment, the hard disk backplane is provided with a third controller, and in response to the volume management device configuration option being the volume management device automatic configuration option, the controller controls the first controller to enable the volume management device function of the third serial bus port corresponding to the in-place hard disk, including:

[0073] Controlling the first controller to generate a hard disk presence information acquisition instruction, and sending the hard disk presence information acquisition instruction to the third controller through the first serial bus;

[0074] Controlling the third controller to perform source verification on the hard disk presence information acquisition instruction;

[0075] In response to successful source verification of the hard disk presence information acquisition instruction, controlling the third controller to acquire hard disk presence information, and returning the hard disk presence information to the first controller via the first serial bus, wherein the hard disk presence information includes a correspondence between the third serial bus port and the hard disk in place;

[0076] According to the hard disk presence information, the first controller is controlled to enable a volume management device function of the third serial bus port corresponding to the hard disk in place.

[0077] Specifically, the third controller is a CPLD that verifies the source of the instruction. If the instruction comes from the first controller, the CPLD returns hard disk presence information to configure the volume management device function. If the instruction comes from the second controller, the third controller is controlled to execute the corresponding light-on operation according to the light-on instruction from the second controller, thus achieving complete decoupling of the first and second controllers.

[0078] In one embodiment, controlling the third controller to perform source verification on the hard disk presence information acquisition instruction includes:

[0079] In response to the third controller receiving the hard disk presence information acquisition instruction, controlling the third controller to parse the hard disk presence information acquisition instruction to obtain the instruction source device;

[0080] In response to the instruction source device being the first controller, determining that the source verification of the hard disk presence information acquisition instruction is successful;

[0081] In response to the instruction source device being the second controller, it is determined that source verification of the hard disk presence information acquisition instruction has failed.

[0082] In one embodiment, the method further comprises:

[0083] In response to completion of configuration of the volume management device, controlling the first controller to generate a release signal, and transmitting the release signal to the arbitrator through the first serial bus;

[0084] In response to the arbitrator receiving the release signal and the second level signal being at a high level, the arbitrator is controlled to hand over the bus control right to the second controller.

[0085] Specifically, the method also includes: controlling the second controller to generate a lighting instruction, and transmitting the lighting instruction to the third controller through the second serial bus; controlling the third controller to verify the source of the lighting instruction; in response to successful source verification of the lighting instruction, controlling the third controller to execute the lighting operation corresponding to the lighting instruction.

[0086] In one embodiment, after returning the hard disk presence information to the first controller via the first serial bus, the method further includes:

[0087] Controlling the first controller to parse the hard disk presence information to obtain a hard disk label and a hard disk connection status, wherein the hard disk connection status includes connected and disconnected;

[0088] Controlling the first controller to obtain a label in a preset legal library, and comparing the hard disk label with the labels in the preset legal library to generate a comparison result;

[0089] In response to the comparison result being consistent, determining that the hard disk is a legitimate hard disk;

[0090] In response to the hard disk connection status being connected, controlling the first controller to set a switch state of a volume management device function corresponding to the third serial bus port to an on state;

[0091] In response to the hard disk connection status being disconnected, the first controller is controlled to set the switch status of the volume management device function corresponding to the third serial bus port to an off state.

[0092] Specifically, the third serial bus port on the first controller's interface has a corresponding volume management device function on / off control option. Normally, this control option is disabled and only needs to be manually enabled when connecting hard drives to a redundant disk array. The first controller detects the hard drive connection status in real time and automatically controls the corresponding volume management device function on / off based on the connection status, improving control efficiency and saving costs.

[0093] It should be understood that although Figure 2 、 Figure 3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 2 、 Figure 3 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0100] The first controller turns on / off the volume management device function of the third serial bus port according to the volume management device configuration option.

[0101] In one embodiment, the arbitration policy includes a request priority, wherein the priority of the first control request is higher than the priority of the second control request.

[0102] The arbitrator analyzes the first control request and the second control request to obtain corresponding first level signals and second level signals;

[0103] When the first level signal is at a high level and the second level signal is at a low level, the arbitrator determines that the bus control right belongs to the first controller;

[0104] When the first level signal is at a low level and the second level signal is at a high level, the arbitrator determines that the bus control right belongs to the second controller;

[0105] When the first level signal and the second level signal are both high level signals, the arbitrator determines that the bus control right belongs to the first controller according to the request priority.

[0106] In one embodiment, when the second controller obtains the bus control right, the first controller generates a third control request and sends the third control request to the arbitrator;

[0115] According to the hard disk presence information, the first controller enables a volume management device function of a third serial bus port corresponding to the hard disk in place.

[0116] In one embodiment, when the third controller receives the hard disk presence information acquisition instruction, the third controller parses the hard disk presence information acquisition instruction to obtain the instruction source device;

[0117] When the instruction source device is the first controller, the third controller determines that the source verification of the hard disk presence information acquisition instruction is successful;

[0118] When the instruction source device is the second controller, the third controller determines that the source verification of the hard disk presence information acquisition instruction fails.

[0119] In one embodiment, when the volume management device configuration is completed, the first controller generates a release signal and transmits the release signal to the arbitrator via the first serial bus;
