The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application.

Generally, before data transmission and storage are performed on a hard disk, the in-place condition of the hard disk needs to be detected, so as to ensure that the data transmission and storage can be performed subsequently. In the actual use process, a certain insertion time is required for hard disk insertion, in the process, the hard disk is likely to be inserted in place but not stable, and in the process, if equipment such as a CPU and the like performs data transmission with the hard disk, errors can be caused in acquisition or output of some transmission data.

However, the existing hard disk detection technology can only identify whether the hard disk is in place or not, and cannot detect whether the hard disk is inserted stably or not.

Aiming at the technical problems, the embodiment of the application provides a device, a method, a logic module and a medium for detecting the in-place stable state of storage equipment, which aim to solve the problem that whether the storage equipment such as a hard disk is stable or not can not be detected in the prior art, and the reliability of the storage equipment in data transmission can be improved by identifying the stable state of the storage equipment. The technical conception of the application is as follows: the logic module in the detection device receives detection signals of the grounding pin and the equipment activity signal pin of the storage equipment to be detected through different interfaces respectively, and then, whether the storage equipment to be detected is plugged in place or not and whether the storage equipment to be detected is plugged in place or not is determined to be stable or not according to the signals transmitted by the grounding pin and the signals transmitted by the equipment activity signal pin, so that the on-site stable state of the storage equipment to be detected is detected by detecting the signals of the two pins of the storage equipment to be detected, and the reliability of the subsequent storage equipment in the data transmission and storage processes is improved.

Fig. 1 is an application scenario diagram of a storage device in-place stability detection device provided by the application. As shown in fig. 1, includes: the device comprises a detection device and a storage device to be detected, wherein the detection device comprises a logic module, at least two interfaces are arranged in the logic module, specifically, a first signal corresponding to a grounding pin in the storage device to be detected is accessed through a preset first interface, and a second signal corresponding to an equipment activity signal pin in the storage device to be detected is accessed through a preset second interface, and then the in-place stable state of the storage device to be detected is determined according to the first signal accessed by the first interface or according to the first signal accessed by the first interface and the second signal accessed by the second interface; the in-place stable state comprises whether the storage device to be detected is plugged in place or not and whether the storage device is plugged in place or not is stable. Specifically, the plugging in-place state of the storage device to be detected can be determined according to the first signal; and when the storage equipment to be detected is in the plugging position, determining the plugging stable state of the storage equipment to be detected through the second signal accessed through the second interface.

It should be noted that, in the logic module in the embodiment of the present application, a plurality of interfaces may be included, and the interface for accessing the first signal and the second signal may be any interface for implementing signal input/output, which is not limited. Optionally, in the case that the storage device to be detected includes a plurality of ground pins, the interface of the logic module may be connected with a signal of any ground pin in the storage device to be detected, so as to obtain a first signal in the storage device to be detected.

Fig. 2 is a schematic structural diagram of a device for detecting a bit stable state of a storage device according to an exemplary embodiment of the present application. As shown in fig. 2, the detection device 1 provided in the present application includes: a logic module 11; the logic module 11 is provided with a first interface and a second interface; the first interface is used for being connected with a grounding pin of the storage device 2 to be detected; the second interface is used for being connected with the equipment activity signal pin of the storage equipment 2 to be detected; the logic module 11 is configured to determine, according to a first signal accessed by the first interface, or according to the first signal and a second signal accessed by the second interface, a stable state of the storage device 2 to be detected in place; the stable state of the bit includes whether the storage device 2 to be detected is plugged in place and whether the plugging is stable when the storage device is plugged in place.

The detection device 1 may be a board card or an integrated circuit chip having signal access and signal detection functions. Optionally, the detecting device 1 may be an external single device, or may be a detecting device 1 built in a preset electronic device or a server, and further, the detecting device 1 is connected with a preset pin of the storage device 2 to be detected through a preset interface, so as to obtain a corresponding detection signal, and realize detection of an in-place stable state of the storage device 2 to be detected. Accordingly, the logic module 11 may be a circuit module or a logic chip having a logic processing function. It should be noted that, in order to realize whether the storage device 2 to be detected is in place or not and whether the storage device 2 to be detected is stable, the logic module 11 in the present application may be provided with a plurality of interfaces, that is, signals corresponding to different pins of the storage device 2 to be detected may be respectively accessed. Specifically, the number of interfaces may be determined according to the number of pins to be detected in the storage device 2 to be detected.

In this embodiment of the present application, the storage device 2 to be detected may be a storage device disposed in an electronic device or a server, or may be a storage device that is separately external and may be connected to the electronic device or the server, so as to store data generated by the electronic device or the server. It should be noted that, the storage device 2 to be detected in the embodiment of the present application is a storage device using a preset interface protocol, for example, the preset interface protocol may be U.2 (SFF-8639) interface protocol, m.2 interface protocol, SAS (Serial Attached SCSI, serial attached SCSI interface) protocol, SATA (Serial Advanced Technology Attachment, serial advanced technology attachment, a serial hardware driver interface based on industry standard) protocol, and an equal interface protocol. Optionally, on the basis of the above interface protocol, the storage device may be an HDD (Hard Disk Drive) or an SSD (Solid State Disk or Solid State Drive, solid State Disk) using any of the above protocols. On this basis, the pins in the storage device 2 to be detected may be a preset ground pin and a device active signal pin in the hard disk power interface, and signals of the ground pin and the device active signal pin are transmitted through the interface of the logic module 11, so that the logic module 11 can detect the in-place stable state of the storage device 2 to be detected according to the signals of the two pins.

In an alternative embodiment, in order to enable the storage device 2 to be detected to transmit signals of the ground pin and the device active signal pin to the logic module 11, interfaces for respectively accessing the two signals, namely a first interface and a second interface, are required to be set in the logic module 11, and the first interface is correspondingly used for being connected with the ground pin to enable the first signal corresponding to the ground pin to be accessed; the second interface is used for being connected with the equipment activity signal pin so as to realize accessing a second signal corresponding to the equipment activity signal pin. Of course, in other embodiments, if it is determined that the signals of the two pins are signals transmitted at different times, only one interface may be provided in the logic module 11, in other words, the first interface and the second interface are the same interface. Specifically, the interface is used for being respectively connected with the two pins to realize that the first signals and the second signals respectively corresponding to the two pins are respectively connected at different moments.

In the application, the logic module 11 detects a first signal corresponding to the first interface access grounding pin, and uses the obtained detection result as a prsnt# (in-place) detection result of the storage device 2 to be detected, so as to realize detection of the in-place plugging state of the storage device 2 to be detected.

Alternatively, a plurality of ground pins may be preset in the storage device. Taking the storage device 2 to be detected as a SATA hard disk as an example, the hard disk includes a power interface for obtaining power for the device, and a data interface for exchanging data with a motherboard and other components of the electronic device or the server.

For example, a schematic diagram of the definition of the pin signals of the pins of the power interface and the data interface in the SATA hard disk can be seen in table 1.

In table 1, the data interface (Signal Segment) includes 7 pins.

Specifically, the grounding pins S1, S4 and S7 are generally connected with the negative electrode; s2, a positive signal pin is sent to data; s3, a negative signal pin is sent to the data; s5, a negative signal pin is received for data; s6, a data receiving positive electrode signal pin.

In Table 1, the Power Segment includes 15 pins.

Specifically, P1-P2 are positive power supply pins, and can be connected with a low-voltage power supply; p3 is DEVSLP ^e Or PWDIS ^e The pins can manage the access and the output of the power supply; P1-P6 are grounding pins, which are generally connected with the negative electrode; P7-P9 are positive power supply pins, which can be connected with a direct current 5V power supply; p10 and P12 are grounding pins, which are generally connected with the negative electrode; p11 is a reserved pin, and can be connected with any signal in DAS, DSS, DHU; P13-P15 are positive power pins, which can be connected with a direct current 12V power supply.

Table 1SATA interface pin signal definition table

Based on the above, the ground pin of the first signal to be detected may be any one of the signals P4-P6, P10 and P12 of the power interface, so the logic module 11 in the present application may detect the signal corresponding to any one of the ground pins. Preferably, based on the position of each ground pin in the power interface, the first interface of the logic module 11 in the embodiment of the present application may be connected to the P4 ground pin to obtain the first signal corresponding to the ground pin.

In the prior art, the SATA hard disk is further disposed on a reserved pin, and the function thereof depends on a specific application scenario and implementation. Typically, this pin is a P11 pin, and the function of this pin is generally defined by the designer according to the external device. In some special cases, the P11 pin may also be used to perform certain specific functions, such as charging, etc. In general, the specific function of the P11 pin is determined by the actual application and hardware design.

In practice, the P11 pin may be configured as a Device Activity Signal (device active signal, DAS) signal. In particular, the signal indicates whether the hard disk drive is in use. When the hard disk drive is in use, the signal is in an active state, and otherwise, the signal is in an inactive state. However, in the prior art, the state of the pin can only determine whether the storage device 2 to be detected is in place, and cannot determine whether the plugging is stable.

Therefore, when the logic module 11 in the application has determined that the storage device 2 to be detected has been plugged in place through the first signal, the logic module can detect through the second signal corresponding to the active signal pin of the second interface access device, and the obtained detection result is used as a plug stable detection result of the detection storage device; and further, the first signal accessed according to the first interface or the second signal accessed according to the first signal and the second interface realizes the detection of the in-place stable state of the storage device 2 to be detected.

In the above technical solution, the logic module 11 obtains the plugging in-place detection condition of the storage device 2 to be detected by accessing a first signal corresponding to the ground pin of the storage device 2 to be detected and accessing a second signal corresponding to the device activity signal pin of the storage device 2 to be detected, and based on the detection result of the first signal; furthermore, the plugging stable detection condition of the storage device 2 to be detected is obtained through the detection results of the first signal and the second signal, so that the reliability of the storage device 2 to be detected in the subsequent data transmission process can be improved.

In an alternative embodiment, the logic module 11 outputs a state signal, which corresponds to whether the storage device 2 to be detected is plugged in place and whether plugging is stable when plugged in place, on the basis of the first signal or on the basis of the first signal and the second signal. The specific steps can be as follows: determining whether the storage device 2 to be detected is spliced in place according to the first signal; when the storage device 2 is plugged in place, whether the storage device 2 to be detected is plugged stably or not is determined according to the second signal.

Specifically, the level state of the first signal is obtained, and whether the storage device 2 to be detected is plugged in place is determined according to the corresponding relation between the level state and the in-place state stored in the logic module 11 in advance. Further, when it is determined that the storage device 2 to be detected is plugged in place, the second signal is received, and whether the storage device 2 to be detected is plugged stably is determined according to the second signal and the signal judgment condition stored in the logic module 11 in advance.

In an alternative embodiment, the logic module 11 of the present application comprises a CPLD chip; correspondingly, the first interface is a first GPIO pin of the CPLD chip, and the second interface is a second GPIO pin of the CPLD chip.

Specifically, a CPLD (Complex Programmable Logic Device ) chip is a digital integrated circuit in which users construct logic functions by themselves according to their needs. The element has the characteristics of flexible programming, high integration level, short design development period, wide application range, advanced development tool, low design and manufacturing cost, low requirement on hardware experience of a designer, no need of testing standard products, strong confidentiality, popularization of price and the like, can realize large-scale circuit design, and is widely applied. Specifically, the CPLD chip includes a GPIO pin, i.e., an input/output interface, which may be configured to receive an external signal, and perform logic processing to obtain a result signal for output.

In the embodiment of the application, any two GPIO pins in the CPLD may be used as the first interface and the second interface. Preferably, because of the connection relationship between the GPIO interfaces and the external components at the interface position of the CPLD chip, the GPIO1 pin may be selected as the first GPIO interface, and used for connecting with the ground pin of the storage device 2 to be detected, so as to implement access to the first signal corresponding to the pin. Likewise, the GPIO2 pin is selected as a second GPIO interface, and is used for being connected with the active signal pin of the device of the storage device 2 to be detected, so as to realize accessing the second signal corresponding to the pin.

It should be noted that, the logic module 11 in the embodiment of the present application may be another module capable of performing judgment processing, for example, an FPGA (Field-Programmable Gate Array, field programmable logic array) chip or other devices, and the first interface and the second interface are two interfaces having an input/output function in the FPGA chip respectively. The embodiment of the present application does not limit the logic module 11.

Fig. 3 is a schematic structural diagram of a device for detecting a bit stable state of a storage device according to another exemplary embodiment of the present application. As shown in fig. 3, the detection device 1 provided in the present application further includes: and a pull-up resistor 12, wherein a first end of the pull-up resistor 12 is connected with a power supply, and a second end of the pull-up resistor 12 is connected with a first interface.

In practice, the pull-up resistor 12 "weakly" pulls the input voltage signal "high" if the external component is not enabled on the wire to which the pull-up resistor 12 is connected. When the external components are disconnected, the external "look" is high impedance to the input. At this time, the voltage at the input port can be pulled up to a high level by the pull-up resistor 12. If the external component is enabled, it will cancel the high level set by pull-up resistor 12. By doing so, the pull-up resistor 12 can enable the pins to maintain a certain logic level even when external components are not connected.

Based on the above principle, in order to accurately determine the level state of the first signal corresponding to the ground pin, the pull-up resistor 12 is connected on the basis of the existing connection relationship of the ground pin. In a specific embodiment, a first end of the pull-up resistor 12 is connected to a power supply, and a second end of the pull-up resistor 12 is connected to a ground pin.

Specifically, after the pull-up resistor 12 is connected, if the level state of the first signal is detected to be a low level, the ground pin is indicated to be connected; otherwise, if the high level is detected, the grounding pin is not connected. The level state of the first signal thus obtained determines the plugging bit state of the memory device 2 to be detected.

In the above technical scheme, by accessing the pull-up resistor 12, accurate detection of the signal corresponding to the grounding pin is further realized, so that the accuracy of the in-place detection result of whether the insertion of the storage device 2 to be detected is improved.

The detection process performed by the logic module is described in detail below in conjunction with FIGS. 4-5. The following embodiments are not intended to limit the technical aspects of the present application.

Fig. 4 is a flowchart of a plug-in bit state detection of a storage device according to another exemplary embodiment of the present application. Referring to fig. 4, based on the above embodiments, the method for determining whether the logic module is in place may specifically include: detecting a level state of the first signal; if the level state of the first signal is a high level state, determining that the storage device to be detected is not spliced in place; or if the level state of the first signal is changed from the high level state to the low level state or is in a continuous low level state, determining that the storage device to be detected is spliced in place.

Specifically, a first signal corresponding to a ground pin is received based on the first interface. On the basis of this, it is judged whether the level state of the first signal is a low level state. Optionally, if the level state of the first signal is a high level state, it is indicated that the ground pin of the storage device to be detected is not connected, and it is further indicated that the storage device to be detected is not plugged in place at present. That is, reliable data transfer with the storage device to be tested is not yet possible. Otherwise, if the level state of the first signal is a low level state, it is indicated that the grounding pin of the storage device is connected, and it is further indicated that the storage device to be detected is plugged in place at present, and whether the storage device to be detected is plugged stably can be detected on the basis.

In an alternative embodiment, the low state of the first signal may include a plurality of situations. Specifically, the low level state may be sustained during the preset detection period or the high level state may be turned over to the low level state. In practical applications, the case where the first signal is continuously in the low state may include, but is not limited to: the storage device to be detected is in the process of powering up the AC power supply, and the level of the first signal is continuously detected in the process until the power up is finished. In the above process, after the storage device to be detected is successfully powered on, the level state of the first signal can be kept in a low level state continuously, which can indicate that the storage device to be detected is in a plugging state. Alternatively, the case where the first signal transitions from a high state to a low state may include, but is not limited to: and the storage equipment to be detected is in the hot plug process. In the process, when the storage device to be detected is pulled down, the first signal is detected to be in a high-level state, hot plug is directly carried out on the storage device to be detected on the basis, the first signal is continuously detected after hot plug, and if the first signal is detected to be converted from the high-level state to the low-level state, the storage device to be detected is indicated to be hot plug in; otherwise, if the first signal is detected to still keep a high-level state after the storage device to be detected is plugged, the storage device to be detected is not plugged in place. It should be noted that the above explanation of the level state of the first signal is merely an exemplary description of the technical solution of the present application, and is not meant as a limitation of the technical solution of the present application.

Fig. 5 is a flowchart of a plug-in stable state detection of a storage device according to another exemplary embodiment of the present application. Referring to fig. 5, on the basis of the above embodiments, the method for determining whether the socket is stable by using the logic module may specifically include: if the storage device to be detected is spliced in place and a preset pulse sequence appears in the second signal within a preset time period, the storage device to be detected is determined to be stably spliced; or if the storage device to be detected is plugged in place and the second signal does not have a preset pulse sequence in a preset time period, determining that the storage device to be detected is plugged in place but not plugged stably.

Because the premise of stable plugging of the storage device to be detected is to be plugged in place, in the embodiment of the application, when the storage device to be detected is detected to be in the plugging in place state at present, the detection process of whether the storage device to be detected is stable in plugging or not can be performed. Otherwise, if the fact that the storage device to be detected is not plugged in place at present is detected, whether the storage device to be detected is plugged stably is detected can be omitted, invalid detection flow is reduced, and detection efficiency is improved.

Specifically, under the condition that the storage device to be detected is spliced in place, a second signal corresponding to the equipment activity signal pin is obtained based on the second interface, and splicing stable detection is carried out. Because the plugging process of the storage device requires time, when the second signal is detected, the second signal within the preset time length needs to be acquired for detection. The reason is that if the second signal is detected immediately at the current time when the plugging in position is detected, a detection result which is not stable in plugging can be obtained, and the detection result at the current time is output; if the storage device to be detected is plugged stably at the next moment, the second signal is not detected again at the moment because the detection result is output at the last moment, so that the finally obtained detection result whether the plugging is stable is inaccurate. Further, if the device maintenance is performed on the storage device to be detected based on the detection result, ineffective maintenance is caused, maintenance time is wasted, maintenance cost is increased, and the service life of the storage device is damaged due to excessive maintenance. Optionally, if the second signal in the preset time period is obtained when the plug-in is detected to be in place, and the obtained signal in the preset time period is detected, the finally obtained detection result is a detection result corresponding to the final state of the storage device to be detected, so that the technical effect of improving the accuracy of the detection result is achieved.

On the basis, a pulse sequence of the second signal in a preset time period can be detected, and whether the storage device to be detected is spliced stably is determined based on a detection result of the pulse sequence. Optionally, if a preset pulse sequence appears in the second signal, determining that the to-be-detected storage device is stable in plugging; and conversely, if the second signal does not have the preset pulse sequence, determining that the storage device to be detected is plugged in place but not plugged stably. By way of example, the preset pulse sequence may include, but is not limited to, more than 2 consecutive pulse sequences.

It should be noted that, in the above-mentioned in-place stable state detection of the storage device to be detected, optionally, if it is detected that the storage device to be detected is not plugged in place, the detection of the current round may be ended, and a state detection result corresponding to the current round is generated, until the next system power-up, restart recovery, hot plug and other conditions of the storage device to be detected occur, the in-place stable state detection is restarted; optionally, if the storage device to be detected is detected to be plugged in place, further plugging stable state detection is required on the basis. Optionally, if the storage device to be detected is detected to be not plugged and stable, ending the state detection of the current round, generating a detection result corresponding to the current round, and similarly restarting the in-place stable state detection until the next system power-on, restarting and recovering, hot plug and other conditions of the storage device to be detected occur; otherwise, if the fact that the to-be-detected storage device is stable in plugging is detected, corresponding detection results are generated, and state detection is finished.

Fig. 6 is a schematic structural diagram of a device for detecting a bit stable state of a storage device according to another exemplary embodiment of the present application. As shown in fig. 6, the detection device 1 provided in the present application further includes: a prompt module 13; the prompt module 13 is connected with the logic module 11; the logic module 11 is used for outputting an in-place stable state signal of the storage device 2 to be detected; the prompting module 13 is configured to generate a plugging prompting signal of the storage device 2 to be detected according to the in-place steady state signal.

In order to enable maintenance personnel or users of storage equipment to know the plugging condition of the storage equipment, the detection device 1 provided by the embodiment of the application is further provided with the prompt module 13 on the original basis so as to timely inform the in-place stable state detection result of the storage equipment 2 to be detected, so that the storage equipment can be maintained timely or reliable data transmission with the storage equipment can be realized.

In an alternative embodiment, the prompting module 13 is connected to the logic module 11, and is configured to receive the status detection signal output by the logic module 11, and generate the socket prompting signal of the storage device 2 to be detected based on the status detection signal.

Specifically, the generated plugging prompt signals are different according to the different state detection signals output by the logic module 11. Optionally, when the logic module 11 outputs a state signal that is not plugged in place, a prompting signal that is not plugged in place is correspondingly generated; and when the logic module 11 outputs a state signal which is plugged in place but not plugged in stable, correspondingly generating a prompting signal which is not plugged in stable, and on the basis, performing thermal maintenance on the storage device 2 to be detected by equipment maintenance personnel based on the prompting signals which are not plugged in place and not plugged in stable, thereby improving maintenance efficiency. Optionally, when the logic module 11 outputs the signal of the in-place and stable state, a prompt signal for the stable insertion of the storage device 2 to be detected is correspondingly generated, which indicates that the storage device 2 to be detected already has the basic condition of data transmission, and the data transmission can be directly performed with the storage device.

In an alternative embodiment, the prompt module 13 is a BMC chip; the BMC chip is specifically used for: and when the storage device 2 to be detected is not plugged stably, a plugging prompt signal is generated to prompt a user to plug the storage device 2 to be detected again.

Specifically, the BMC (Baseboard management controller ) chip is a small operating system independent of the server system, is a chip integrated on the motherboard, and also has a product which is inserted on the motherboard in a PCIE format or the like, and has only a standard RJ45 network port as an external expression format, and has a firmware system of independent IP. In this embodiment of the present application, the BMC chip has signal access and signal processing functions, so that a corresponding prompt signal may be generated based on the state detection signal input by the logic module 11.

In the above scheme, after the logic module 11 outputs the detection signals corresponding to the detection results of each state of the storage device 2 to be detected, the prompting module 13 generates the corresponding prompting signals to perform the corresponding prompting based on the detection signals, so that the storage device can be maintained in time, and the maintenance efficiency of the device is improved; or, the data transmission with the storage device can be timely and reliably realized, and the data transmission reliability and transmission efficiency of the device are improved.

The detection device 1 in this embodiment has the same advantages as the detection device 1 described in the above embodiments, and will not be described in detail here.

Fig. 7 is a schematic structural diagram of an electronic device 01 provided in the present application. Referring to fig. 7, the electronic device 01 comprises a detection means 1 and at least one storage device 2 to be detected.

Note that, the electronic device 01 in the embodiment of the present application may be a server. In particular, the electronic device 01 may include, but is not limited to, products in which the electronic device 01 is intended to represent various forms of digital computers, such as laptops, desktops, workstations, etc., and various forms of mobile devices, such as personal digital assistants, cellular telephones, smartphones, wearable devices (e.g., helmets, eyeglasses, watches, etc.), and other similar computing devices. Servers include, but are not limited to, blade servers, mainframe computers, and other suitable computers. The storage device 2 to be detected can be a storage device arranged in the electronic device 01 or the server, or can be a storage device which is singly arranged and can be connected with the electronic device 01 or the server, so as to realize the storage of data generated by the electronic device 01 or the server. It should be noted that, the storage device 2 to be detected in the embodiment of the present application is a storage device using a preset interface protocol, for example, the preset interface protocol may be U.2 (SFF-8639) interface protocol, m.2 interface protocol, SAS (Serial Attached SCSI, serial attached SCSI interface) protocol, SATA (Serial Advanced Technology Attachment, serial advanced technology attachment, a serial hardware driver interface based on industry standard) protocol, and an equal interface protocol. Optionally, on the basis of the interface protocol, the storage device may be a mechanical hard disk or a solid state hard disk using any one of the protocols.

Specifically, the detection device has been described in detail in the above embodiments for the detection process of the state of the storage device 2 to be detected, so that a detailed description thereof is omitted herein.

In the above technical scheme, the detection device included in the electronic device 01 obtains the signals corresponding to the grounding pin and the signals corresponding to the equipment activity signal pin in the storage device 2 to be detected through different interfaces, and obtains the plugging in-place stable condition of the storage device 2 to be detected by detecting the two signals, thereby realizing the technical effect of improving the reliability of the storage device 2 to be detected in the subsequent data transmission process.

On the basis of the above embodiments, the technical solution of the present application further provides a preferred embodiment. Fig. 8 is a schematic structural diagram of a device for detecting a bit stable state of a storage device according to the present preferred exemplary embodiment. Referring to fig. 8, in the preferred embodiment, the logic module is a CPLD chip, and the detection process of the in-place stable state is specifically described under different common conditions by taking the to-be-detected storage device as an SAS/SATA hard disk as an example.

Specifically, in fig. 8, the CPLD chip includes a GPIO1 pin and a GPIO2 pin. Connecting the GOIP1 pin with a P4 pin, namely a GND pin, of the hard disk to send a PRSNT# signal to the CPLD; the GPOI2 pin is connected with the P11 pin of the hard disk, namely the DAS pin, so as to realize the transmission of DAS signals to the CPLD. Furthermore, the CPLD chip is also connected with the BMC chip to realize the prompt of plugging signals based on the detection result.

Alternatively, if the hard disk is powered on for the first time at the current moment, the CPLD's steady state detection process in place may be seen in fig. 9. Specifically, the CPLD detects the signal output states of the P4 and P11 pins during the power-on BIOS Post process. If the P4 pin is detected to be in a low level state all the time and the P11 pin outputs more than 2 continuous pulses, the hard disk can be judged to be inserted stably; if the P4 pin is detected to be in a low level state, the CPLD judges that the hard disk is not in place, or if the P4 pin is detected to be in a low level state all the time, but the P11 pin does not continuously output more than 2 pulses, the CPLD judges that the hard disk is not inserted and stabilized. On the basis, the related fault information which is not in place or is not inserted stably is transmitted to the BMC chip, so that the BMC chip generates alarm information, and a user can perform quick thermal maintenance when identifying a fault error. Furthermore, after the BIOS Post is finished, the detection is stopped until the next system power-on or restarting is performed, and the hard disk in-place plug-in stability detection is performed again.

Alternatively, if the hard disk is hot swapped at the current moment, the CPLD's in-place steady state detection process may refer to fig. 10. Specifically, if the CPLD detects that the logic of the pin P4 of the hard disk turns over (switches from high level to low level), and detects that the pin P11 outputs more than 2 continuous pulses within 2 minutes (the inserted hard disk is identified by the OS), it can be determined that the hard disk has been inserted stably; otherwise, if the CPLD does not detect that the signal logic of the pin P4 of the hard disk turns over (continuously keeps high level), the CPLD judges that the hard disk is not in place; or if the CPLD detects that the logic of the P4 pin signal of the hard disk is inverted (switched from high level to low level), but within 2 minutes (the process of inserting the hard disk and identifying by the OS) the CPLD does not detect that the P11 pin output is continuous for more than 2 pulses, the CPLD judges that the hard disk is not inserted stably. On the basis, the related fault information which is not in place or is not inserted stably is transmitted to the BMC chip, so that the BMC chip generates alarm information, and a user can perform quick thermal maintenance when identifying a fault error.

According to the technical scheme, the CPLD judges whether the hard disk is in place or not based on the detected signal corresponding to the P4 pin, and judges whether the hard disk is stable in insertion or not based on the signal corresponding to the P11 pin when the hard disk is in place, so that an in-place stable detection result of the hard disk is obtained, and the reliability of the hard disk in the subsequent data transmission process is improved.
