In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the above object, a first aspect of the embodiments of the present invention proposes an embodiment of a signal management apparatus for a server. As shown in fig. 1, the signal management apparatus specifically includes:
a hard disk backplane 110 comprising a plurality of hard disks 111;
a microcontroller 120 connected to the hard disk 111;
a hardware device 130 connected to the microcontroller 120;
wherein the hardware device is configured to output an SGPIO signal to the microcontroller, and the microcontroller is configured to control lighting of a lamp on a corresponding hard disk based on the received SGPIO signal.
The SGPIO bus is a serial bus, and compared with a parallel bus, the SGPIO bus has the advantages of simple structure, less occupied I/O pins, low cost and the like, and the SGPIO bus replaces the parallel bus to realize data transmission in various forms.
The SGPIO bus has 4 signal lines which are SClock/SLoad/SDataOut/SdaIn respectively, and the specific definition is as follows:
SClock: a clock line driven by the initiating device, with a maximum of 100kHz, typically using 48 kHz;
SLoad: driven by the start device, synchronized with SClock, this signal indicates that the bit stream is about to end and a new round of bit stream is to be restarted, indicating the start of a new frame of data.
SDataOut: a serial signal driven by the initiator device to the target device.
SDataIn: a serial signal driven by the target device to the initiator device.
SClock and SLoad signals are used for controlling the unidirectional transmission of two serial signals SDataOut and SDataIn.
In this embodiment, the SLoad is configured to define vendor information of the hardware device, and transmit the vendor information to a corresponding hard disk on the hard disk backplane based on the microcontroller; the SDataOut is used for defining lighting information of each hard disk on the hard disk backboard and controlling the corresponding LED lamp to be lighted; SDataIn is used by the hard disk backplane for some cases of returning to the hard disk on the hard disk backplane.
The hardware device refers to a RAID Card or a PCH or an interleaved combination of a plurality of RAID cards, and is a signal source of each hard disk on the hard disk backplane.
According to the embodiment of the invention, the connection between the hardware equipment and the microcontroller is realized through the SGPIO signal, the SGPIO signal is analyzed based on the microcontroller, and the source of the signal can be identified by which hardware equipment is, so that the realization mode is simple, the identification accuracy is high, the hardware cost is reduced, and the use of cables is reduced.
In some embodiments, the SGPIO signal includes a SLoad signal configured to define vendor information for the hardware device and to transmit the vendor information to the microcontroller.
In some embodiments, the microcontroller is configured to compare the received vendor information with predefined external source data information, and determine a hardware device to access the hard disk based on a comparison result.
In some embodiments, the SGPIO signal further includes an SDataOut signal configured to define lighting information for the hard disk and send the lighting information to a hard disk backplane through the microcontroller to control lighting of lights on the corresponding hard disk.
As shown in fig. 2, a schematic diagram of transmission of each signal in the SGPIO provided by the present invention is shown.
In fig. 2, the SLoad signal indicates when the bitstream ends and restarts. With SLoad set to 1, the initiator should send a vendor specific pattern at the next four bit positions on SLoad, where the vendor defines the information to be transferred to the target. After that, the originator should set SLoad to 0 until a new round of bitstream is to be restarted.
Fig. 3 is a schematic diagram of the transmission of the SDataOut signal in fig. 2.
SdaOut defines lighting information of the SGPIO on the HDD, every 3 bits are used as lighting or non-lighting information of 3 LEDs of one HDD, Bit 1 is an Activity LED, Bit 2 is a Locate LED, and Bit 3 is a Fail LED.
In this embodiment, a digital code for controlling a lighting mode of a hard disk on the HDD BP and each external signal source (i.e., hardware device) is defined on the SGPIO, and is correspondingly defined on the MCU. After the SGPIO signal is transmitted to the MCU, the MCU analyzes different lighting methods and controls the lights on the corresponding hard disks to light up, for example, if an RAID Card corresponds to 4 hard disks on the hard disk backplane, there will be 3 bits multiplied by 4 HDDs, i.e., there are 12bits to make the lights of 4 hard disks; if the RAID Card corresponds to 8 hard disks on the hard disk backboard, 3 bits are multiplied by 8 HDDs, namely 12bits are used as lamp signals of the 8 hard disks. When the SLoad of the SGPIO maintains a low level, it means that the hardware device is still transmitting the lighting signal of the LED.
For example, table 1 shows the simplest way of defining the same code by the system supplier behind the SLoad, i.e. after the start bit is sent by the SLoad, the same digital code is defined in the sections L0, L1, L2, and L3 in fig. 2, and after the signal is sent to the MCU, the MCU can distinguish what RAID Card or PCH the signal source is.
