It is used by the global server industry for communication between host bus adapters (HBAs) / redundant arrays of inexpensive disks (RAID) controllers and SAS / SATA hard drive backplanes. The HBA / RAID controller uses the SGPIO bus to obtain the status of the hard drive sockets on the backplane and to send hard drive LED (light-emitting diode) status indication signals.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0039] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two different entities or different parameters with the same name. Therefore, "first" and "second" are merely for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as other steps or units inherent in a process, method, system, product, or device that includes a series of steps or units.

[0040] Based on the above objectives, the first aspect of the present invention provides an embodiment of a hard disk lighting method. Figure 1 The diagram shown is a schematic representation of an embodiment of the hard disk LED lighting method provided by the present invention. Figure 1 As shown, the embodiments of the present invention include the following steps:

[0041] Step S10: Determine multiple GPIO ports to be used based on the SGPIO bus protocol. The multiple GPIO ports include a first GPIO port, a second GPIO port, and a third GPIO port, which correspond to the SClock signal, SLoad signal, and SDataOut signal in the SGPIO bus, respectively.

[0042] Step S20: Receive initialization instructions from the user for multiple GPIO ports, and initialize the multiple GPIO ports based on the initialization instructions;

[0043] Step S30: Receive the hard drive light indicator sent by the user, and based on the hard drive light indicator and the GPIO protocol, make the first GPIO port and the second GPIO port output pulse signals of corresponding level states in sequence.

[0044] Step S40: Traverse all the LEDs on the hard drives, and output the corresponding level pulse signal from the third GPIO port according to the LED status information in the hard drive LED indicator, and realize the LED of the corresponding hard drive based on the pulse signal output from the third GPIO port.

[0045] This invention utilizes multiple GPIO ports in an embedded system to programmatically output pulse signals that conform to the SGPIO protocol and perform the same functions as the SClock, SLoad, and SdataOut signals. This achieves the same effect as configuring a dedicated SGPIO controller register to output SGPIO signals in existing technologies. This software simulation eliminates the need for a dedicated SGPIO controller integrated into the system-on-a-chip (SoC). By controlling the GPIO registers through low-level software programming, the waveform and timing of SGPIO are implemented, and an easy-to-use API interface is provided to upper-level callers. This reduces controller costs and the number of ports in SoC design.

[0046] GPIO (General-purpose input / output) is similar in function to P0-P3 of the 8051 microcontroller. Its pins can be freely used by the user through programming. Depending on practical considerations, the pins can be used as general-purpose inputs (GPI), general-purpose outputs (GPO), or general-purpose input and outputs (GPIO). For inputs, the pin level can be determined by reading a register; for outputs, a high or low level can be set by writing to a register; other special functions are controlled by separate registers.

[0047] SGPIO (Serial General-purpose input / output) is a bus protocol developed by the SFF committee for communication between RAID (Redundant Arrays of Inexpensive Disks) / HBA (Host Bus Adapter) cards and hard drive backplanes.

[0048] Figure 2 This is a schematic diagram illustrating typical SGPIO signal relationships defined by SFF-8485 (SFF being a committee) according to an embodiment of the present invention. For example... Figure 2 As shown in Table 1, the signals of the SGPIO bus (Serial General-purpose input / output, a bus protocol defined by the SFF committee for communication between RAID / HBA cards and hard drive backplanes) defined by SFF-8485 are as follows:

[0050]

[0051] In some embodiments, the lights for each hard drive include at least an activity indicator, a fault indicator, and a location indicator.

[0052] According to the protocol, every 3 bits in the bitstream on SDataOut and SDataIn indicate the status of a Drive (hard drive), representing the status of the activity / locate / error indicator lights (activity / location / fault indicators), respectively. The bitstream is restarted after the SLoad model is set to 1. The bitstream contains key information for at least 4 drives. The bitstream does not need to be the same length each time; it can end at any position of the 3rd bit of Drive3 and start a new round of bitstream transmission.

[0053] In some embodiments, initializing multiple GPIO ports based on an initialization instruction includes: reading the port numbers of multiple GPIO ports, configuring an initial state for the multiple GPIO ports, the initial state including at least an initial level state, and initializing the GPIO clock to be used.

[0054] In some embodiments, the method of causing the first GPIO port and the second GPIO port to sequentially output pulse signals of corresponding level states based on the hard disk light indicator and the GPIO protocol includes: causing the first GPIO port to output pulse signals of corresponding level states based on the hard disk light indicator and the GPIO protocol, and maintaining them for a specified number of clock cycles; and causing the second GPIO port to output pulse signals of corresponding level states, and maintaining them for a specified number of clock cycles.

[0055] In some embodiments, causing the third GPIO port to output a pulse signal of a corresponding level state according to the lamp status information in the hard disk lamp indicator includes: causing the third GPIO port to output a pulse signal of a corresponding level state according to the lamp status information in the hard disk lamp indicator, and maintaining it for a specified number of clock cycles.

[0056] In some embodiments, the level state is a high level state or a low level state, and the lamp status information is a first status information corresponding to the high level state or a second status information corresponding to the low level state.

[0057] In some embodiments, the hard drive indicator includes a status indication of the corresponding light on all hard drives, including an on or off state.

[0058] The following are specific embodiments of the hard disk LED lighting method of the present invention:

[0059] Figure 3 This is a schematic diagram of a software implementation framework for simulating SGPIO using GPIO, provided according to an embodiment of the present invention. Figure 3 As shown, this embodiment encapsulates an SGPIO_HAL (SGPIO Hardware Abstraction Layer) layer on top of the GPIO_DEV (GPIO Device) driver layer of the embedded operating system, providing upper-layer users with API (Application Program Interface) functions to implement hard disk LED lighting functions. Internally, it implements basic SGPIO signal waveforms by calling GPIO driver layer functions.

[0060] I. The API interfaces provided to users include:

[0061] Led_Ctrl_Init: Initializes the Led_Ctrl port;

[0062] Led_Ctrl_Action(uint8 drive_num,struct driveStatus*pdrive_status):

[0063] The specific interface for controlling the LED status is defined as follows: drive_num is the total number of drives (hard drives) that SGPIO needs to control, and pdrive_status indicates the active / error / locate LED status that each drive needs to display.

[0064]

[0065] II. The SGPIO_HAL layer interface includes:

[0066] Sgpio_Port_Init: Initializes and configures the GPIO ports that will be used.

[0067] SClock_High / Low: Configures the SClock port with high or low voltage levels;

[0068] SLoad_High / Low: Configures the high / low level of the SLoad port;

[0069] SDataOut_High / Low: Configures the high / low level of the SDataOut port;

[0070] Action_Set(struct driveStatus*pdrive_status): Sets the LED status of a single drive, with the specific status indicated by pdrive_status (i.e., the hard drive LED indicator).

[0071] Action_Start: Configures the SClock and SLoad signals before Action_Set.

[0072] III. The GPIO_DEV layer functions called include:

[0073] RCC_GPIO_CLK_INIT: Initializes the clock for the GPIO family used;

[0074] GPIO_INIT: Initializes the parameters of the GPIO ports used, such as port number, input / output direction, pull-up / pull-down type, and speed.

[0075] GPIO_OUT: Sets the high and low levels of the output of the specified GPIO port, which is achieved by writing to the register.

[0076] During initialization, LED_CTRL_INIT mainly uses the GPIO_OUT interface to configure the GPIO ports that need to be used, which are read from the configuration file or global variables, to their default states (open-drain output / pull-up / high speed / default level low), and initializes the GPIO clock to put the GPIO ports into the ready state.

[0077] Figure 4 According to Figure 3 The provided flowchart illustrates the Action_Start process. (Example) Figure 4 As shown, when Led_Ctrl_Action executes, it first calls Action_Start, which pulls up the clock signal and the SLoad signal as specified in the protocol, indicating that configuration has begun. HALF_CYCLE represents half a clock cycle, which can be configured from 5µs to 17ms according to the protocol.

[0078] Figure 5 According to Figure 3 The provided flowchart illustrates the Action_Set process. (For example...) Figure 5 As shown, after the Action_Start process is completed, Action_Set (i.e. Active_Set) is called to configure each of the drive_num (number of hard drives).

[0079] This embodiment, on an embedded operating system, encapsulates the GPIO underlying driver interface provided by the operating system to realize the simulation of SGPIO signals that conform to the waveform and timing requirements specified by the SFF-8485 protocol through software.

[0080] A second aspect of the present invention also provides a hard disk lighting system. Figure 6 The diagram shown is a schematic representation of an embodiment of the hard disk LED lighting system provided by the present invention. Figure 6As shown, a hard drive LED lighting system includes: a port signal module 10, configured to determine multiple GPIO ports to be used based on the SGPIO bus protocol, the multiple GPIO ports including a first GPIO port, a second GPIO port, and a third GPIO port corresponding to the SClock signal, SLoad signal, and SDataOut signal in the SGPIO bus, respectively; an initialization module 20, configured to receive user initialization instructions for the multiple GPIO ports and initialize the multiple GPIO ports based on the initialization instructions; an output module 30, configured to receive hard drive LED lighting instructions from the user and, based on the hard drive LED lighting instructions and the GPIO protocol, cause the first GPIO port and the second GPIO port to sequentially output pulse signals of corresponding level states; and an LED lighting module 40, configured to traverse the LEDs of all hard drives and, according to the LED status information in the hard drive LED lighting instructions, cause the third GPIO port to output pulse signals of corresponding level states, and realize the lighting of the corresponding hard drive based on the pulse signals output by the third GPIO port.

[0081] The hard disk LED lighting system of this invention uses multiple GPIO ports and software programming in an embedded system to output pulse signals that conform to the SGPIO protocol and perform the same function as the SClock, SLoad, and SdataOut signals. This achieves the same effect as the prior art of outputting SGPIO signals by configuring a dedicated SGPIO controller register. Through this software simulation method, there is no need for a dedicated SGPIO controller to be integrated into the system-on-a-chip. The waveform and timing of SGPIO are realized by controlling the GPIO register through low-level software programming, and an easy-to-use API interface is provided to the upper-level caller. This reduces the controller cost and the number of ports for the design of the system-on-a-chip.

[0083] Based on the SGPIO bus protocol, multiple GPIO ports to be used are determined. These multiple GPIO ports include a first GPIO port, a second GPIO port, and a third GPIO port, which correspond to the SClock signal, SLoad signal, and SDataOut signal in the SGPIO bus, respectively.

Then, based on the pulse signal output by the third GPIO port, activate the corresponding hard drive LED.

[0087] In some embodiments, initializing multiple GPIO ports based on an initialization instruction includes: reading the port numbers of multiple GPIO ports, configuring an initial state for the multiple GPIO ports, the initial state including at least an initial level state, and initializing the GPIO clock to be used.
