[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 A flowchart of a storage system fault monitoring method provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method is used in a controller and includes:

[0058] S101, sending a first control signal to the extension chip to control the extension chip to monitor the uplink state and downlink state of the extension chip; the controller is connected to the extension chip.

[0059] It should be noted that the storage system can be a server or device with storage function. The expansion chip (expander) can convert and expand the upstream signal, and the downstream can support hard disks, such as hard disks with Serial Attached SCSI (SAS) or hard disks with hard disk interface specifications (Serial Advanced Technology Attachment, SATA).

[0060] When the present invention is applied to a server, the controller may be a baseboard management controller (BMC), which is a microcontroller used for server management. Of course, the controller may also be other controllers, depending on the actual application situation, which is not limited here. The following mainly describes the baseboard management controller as an example.

[0061] Figure 2 The following is a schematic diagram of the connection of the baseboard management controller, expansion chip, backplane programmable logic device, and hardware provided in the embodiment of the present invention. Figure 2 As shown, the baseboard management controller of the present invention can be directly connected to the expansion chip expander, and the baseboard management controller can send a first control signal to the expansion chip expander. After receiving the first control signal, the expansion chip expander can monitor the uplink state and downlink state of the expansion chip expander.

[0062] S102: Acquire fault information in the uplink and downlink of the extension chip according to the uplink state and downlink state of the extension chip.

[0063] In implementation, the present invention can obtain the uplink of the expansion chip expander according to the uplink status of the expansion chip expander monitored in step S101; and obtain the fault information in the downlink of the expansion chip expander according to the downlink status of the expansion chip expander monitored in step S101. After obtaining the fault information in the uplink and downlink of the expansion chip, the present invention can alarm and light up the fault at the corresponding position of the fault information, further enabling the staff to discover the corresponding fault in time and predict the risk in advance.

[0064] S103, sending a second control signal to the backplane programmable logic device to control the backplane programmable logic device to detect the heartbeat signal of the extension chip; the controller and the extension chip are both connected to the backplane programmable logic device.

[0065] It should be noted that the heartbeat signal of the expansion chip expander is a periodic signal used to monitor and feedback the working status of the expansion chip expander. The heartbeat signal can be a digital signal, such as the periodic switching of high level and low level, or a specific data frame, pulse sequence, etc. When the expansion chip expander works normally, the heartbeat signal is automatically sent at a certain time interval. Just like the human heartbeat can reflect the health of the body, the heartbeat signal of the expansion chip expander can reflect whether its own working status is normal.

[0066] In implementation, the backplane programmable logic device of the present invention can be a complex programmable logic device (CPLD) or other programmable logic devices. Figure 2 As shown, the backplane programmable logic device can be directly connected to the baseboard management controller, or directly connected to the expansion chip expander. The baseboard management controller can send a second control signal to the backplane programmable logic device, and after receiving the second control signal, the backplane programmable logic device can detect the heartbeat signal of the expansion chip expander to detect the fault information that the expansion chip cannot self-check.

[0067] S104, reading the heartbeat signal of the expansion chip. If the heartbeat signal of the expansion chip is not within the set range, it is confirmed that the expansion chip is in a dead state.

[0068] It should be noted that the controller can read the heartbeat signal of the expansion chip expander detected by the backplane programmable logic device, and can understand in real time whether the expansion chip expander is operating normally. When the expansion chip expander fails or an abnormal situation occurs, the heartbeat signal may be interrupted, become irregular, or stop sending. The above-mentioned setting range can be understood as the health status signal of the heartbeat signal, and does not include interrupted, irregular, or stopped sending signals. The heartbeat signal of the expansion chip expander can be set to 1 when it is within the set range, and can be set to 0 when it is not within the set range. When the heartbeat signal of the expansion chip expander read is 0, it is directly determined that the expansion chip expander is in a dead state, and an alarm is prompted. The backplane programmable logic device can record the dead state of the expansion chip. In this way, by monitoring the heartbeat signal, the abnormality of the expansion chip expander can be discovered in time for troubleshooting and repair.

[0069] In the above-mentioned storage system fault monitoring method provided by the embodiment of the present invention, the controller is connected to the expansion chip expander, and the controller and the expansion chip expander are both connected to the backplane programmable logic device. The expansion chip expander is controlled to monitor its uplink and downlink status, and the backplane programmable logic device is controlled to detect the heartbeat signal of the expansion chip expander, thereby obtaining the fault information in the uplink and downlink of the expansion chip expander, and confirming whether the expansion chip expander is in a hung state. In this way, through the fault information in the uplink and downlink of the expansion chip expander, and the hung state of the expansion chip expander, storage-related faults can be predicted in advance, which is helpful for business unloading and maintenance before the fault occurs. The fault can be quickly located after the fault occurs, and the operation of collecting log files of various storage components, extracting fault features from the log files, and matching with a preset feature database to locate the fault location can be avoided, saving fault detection time, thereby ensuring the high reliability of the storage device and reducing the impact on business operations.

[0070] Furthermore, in a specific implementation, the above-mentioned storage system fault monitoring method provided in an embodiment of the present invention may also include: sending a third control signal to the extension chip to control the extension chip to perceive the main body information; polling the register in the extension chip to obtain the main body information perceived by the extension chip, and extracting the main body unhealthy state of the extension chip from the main body information perceived by the extension chip.

[0071] In implementation, the expansion chip expander of the present invention can realize self-checking. The baseboard management controller can send a third control signal to the expansion chip expander. After receiving the third control signal, the expansion chip expander can sense its own information and save it to the relevant register. The baseboard management controller can poll the registers in the expansion chip expander to obtain the self information sensed by the expansion chip expander. The baseboard management controller can extract the abnormal state of the expansion chip expander from the obtained information.

[0072] In specific implementation, the above steps of controlling the extended chip to sense the main body information may specifically include: controlling the extended chip to sense the information of the clock module, the integrated circuit bus module, and the port physical layer module in the extended chip and storing them in the register.

[0073] Correspondingly, the above steps obtain the entity information perceived by the extension chip, and extract the entity unhealthy state of the extension chip from the entity information perceived by the extension chip, which can specifically include: obtaining information of the clock module, the integrated circuit bus module, and the port physical layer module in the extension chip, and parsing the information of the clock module, the integrated circuit bus module, and the port physical layer module in the extension chip to extract the entity unhealthy state of the extension chip.

[0074] In implementation, the expansion chip expander can sense the information of the clock module, the Inter-Integrated Circuit (I2C) module, and the port physical layer (PHY) module in the expansion chip expander and store them in the corresponding registers. The controller can obtain the information of the clock module, the integrated circuit bus module, and the port physical layer module in the expansion chip expander from the interactive register and parse it. When at least one module has an abnormality, the abnormality is extracted to obtain the unhealthy state of the expansion chip expander.

[0075] Furthermore, in a specific implementation, in the storage system fault monitoring method provided in the embodiment of the present invention, the expansion chip may be upstream connected to the expansion card; and the expansion card may be connected to the processor.

[0076] In implementation, the expansion card may be a host bus adapter (HBA), which is an expansion card plugged into a server and used to connect the server to a storage network. The HBA card enables the server to exchange data with an external storage device at high speed. The expansion card HBA of the present invention can convert the high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE) protocol and the SAS protocol to achieve expansion functions. The controller of the present invention does not obtain relevant information from the expansion card.

[0077] Correspondingly, step S102 acquires fault information in the uplink of the extension chip according to the uplink status of the extension chip, which may specifically include: acquiring link fault information between the extension chip and the extension card from the uplink status of the extension chip.

[0078] Figure 3 A schematic diagram of the relationship between the components corresponding to the storage system fault monitoring method provided by the embodiment of the present invention. Figure 3 As shown, the baseboard management controller of the present invention can obtain the link failure information between the expansion chip expander and the expansion card HBA from the uplink status of the expansion chip expander. It should be noted that Figure 3The thick lines in the figure represent the storage topology, and the thin lines represent the monitoring topology.

[0079] Furthermore, in the above steps, obtaining the link fault information between the extension chip and the extension card from the uplink status of the extension chip may specifically include: polling the register in the extension chip to obtain the link rate information and the link bandwidth reduction information between the extension chip and the extension card from the uplink status of the extension chip; and analyzing the link rate information and the link bandwidth reduction information between the extension chip and the extension card to obtain the link fault information between the extension chip and the extension card.

[0080] In implementation, the controller of the present invention can poll the register in the expansion chip expander, and extract the link rate information and link bandwidth reduction information between the expansion chip expander and the expansion card HBA from the uplink status of the expansion chip expander. The controller can analyze the extracted link rate information and link bandwidth reduction information between the expansion chip expander and the expansion card HBA, and obtain the link fault information between the expansion chip expander and the expansion card HBA according to the analysis result. That is, the present invention can use the interactive registers of the expansion chip expander and the controller to obtain fault information such as uplink rate abnormality, uplink bandwidth abnormality or uplink error exceeding the standard.

[0081] In specific implementation, in the above storage system fault monitoring method provided by the embodiment of the present invention, if Figure 3 As shown, the expansion chip expander can be connected to at least one hard disk downstream, thus forming a multi-level storage system.

[0082] Correspondingly, step S102 obtains fault information in the downlink of the extension chip according to the downlink status of the extension chip, which may specifically include: obtaining the unhealthy status of each hard disk downstream connected to the extension chip from the downlink status of the extension chip.

[0083] In implementation, the controller of the present invention can obtain the abnormal status of each hard disk hung under the expansion chip expander from the downlink status of the expansion chip expander, realize hard disk failure prediction, further support early risk prediction, and improve positioning accuracy.

[0084] Furthermore, in the above steps, the unhealthy status of each hard disk connected downstream to the expansion chip is obtained from the downlink status of the expansion chip, which may specifically include: polling the register in the expansion chip, and obtaining the status information of each hard disk connected downstream to the expansion chip from the downlink status of the expansion chip; parsing the status information of each hard disk to obtain the self-monitoring analysis and report status results of each hard disk; judging whether the remapped sector count in the attribute is greater than the set threshold value according to the self-monitoring analysis and report status results of each hard disk, and if so, judging that the sector is damaged.

[0085] In implementation, the controller of the present invention can poll the register in the expansion chip expander, and obtain the status information of each hard disk attached to the expansion chip expander from the downlink status of the expansion chip expander. Afterwards, the controller can parse the status information of each hard disk and obtain the self-monitoring analysis and reporting status results (Self-Monitoring Analysis and Reporting Technology, SMART) of each hard disk. According to the SMART result, it is judged whether the remapped sector count in the attribute is greater than the set threshold to judge whether the sector is damaged.

[0086] It should be noted that the remapped sector count (Reallocated Sector Count) is used to record the number of reallocated sectors. Each hard disk has a certain number of spare sectors, which are used to replace the sector when a read or write error occurs in a normal sector to maintain the stability of the hard disk and data. The present invention can enable spare sectors to replace damaged sectors (i.e., remapping) according to SMART. Before the number of remapped sectors reaches the set threshold, hard disk manufacturers recommend that data backup be done to avoid data loss due to physical damage to the hard disk. The initial value of the remapped sector count is 0, and it will gradually increase and will not decrease. If a brand new hard disk continuously increases the number of remapped sectors in a short period of time, it means that the quality of this hard disk is low and there are hidden dangers in stability.

[0087] In addition, the present invention can also utilize the interactive registers between the expansion chip expander and the controller to obtain fault information such as abnormal downlink rate, downlink disconnection, and abnormal health status of the attached hard disk. It can be understood that the expansion chip expander of the present invention can monitor the status of the link between the expansion card HBA and the expansion chip expander, the downlink status, the self-test status, and the status of the attached hard disk through in-band link analysis. The faults that can be monitored by the present invention include link speed reduction, link bandwidth reduction, link disconnection, self-test abnormality, unhealthy hard disk status, etc. The expansion chip expander continuously monitors the link status and self-test status, and records them in the interactive register with the controller.

[0088] Table 1 Detection of the expansion chip uplink, downlink and attached hard disk

[0089]

[0090] As can be seen from Table 1, the expansion chip expander and the baseboard management controller of the present invention are designed with interactive registers. The baseboard management controller can poll the expansion chip expander related registers to confirm whether a storage fault occurs, 1=no problem, 0=abnormal. After polling an abnormality, the baseboard management controller needs to record an alarm and can also turn on a fault light as needed.

[0091] Furthermore, in a specific implementation, in the above-mentioned storage system fault monitoring method provided in an embodiment of the present invention, step S104 reads the heartbeat signal of the expansion chip, which may specifically include: polling the registers of the backplane programmable logic device, analyzing the register information corresponding to the backplane programmable logic device; and obtaining the heartbeat signal of the expansion chip based on the analysis results.

[0092] In implementation, the expander heartbeat signal of the expansion chip of the present invention is connected to the backplane programmable logic device. After the backplane programmable logic device is powered on, the controller can poll the register of the backplane programmable logic device, and then analyze the register information corresponding to the backplane programmable logic device, and obtain the expander heartbeat signal of the expansion chip according to the analysis result. If the backplane programmable logic device detects that the expander heartbeat signal of the expansion chip is abnormal, the interactive register of the backplane programmable logic device and the baseboard management control can be set.

[0093] Table 2 Detection of extended chip

[0094]

[0095] As can be seen from Table 2, the backplane programmable logic device and the baseboard management controller are designed with interactive registers. The baseboard management controller can poll the relevant registers of the backplane programmable logic device to obtain the status of the expansion chip expander. The expansion chip expander will send a heartbeat when it works normally. When the backplane programmable logic device normally obtains the heartbeat, it is recorded as 1. When the backplane programmable logic device cannot detect the heartbeat signal of the expansion chip expander or the detected heartbeat signal is abnormal, it is recorded as 0. When the baseboard management controller reads the record of 0, it means that after polling the abnormality, the baseboard management controller needs to record an alarm, and can also turn on the fault light as needed.

[0096] Furthermore, in a specific implementation, the above storage system fault monitoring method provided in the embodiment of the present invention may also include: monitoring a signal (power good) in the expansion card for detecting the stability of the power supply output voltage, so as to detect the power supply status of the expansion card in real time; monitoring at least one signal in the expansion chip for detecting the stability of the power supply output voltage, so as to detect the power supply status of the expansion chip in real time.

[0097] Figure 4 The monitoring module provided in the embodiment of the present invention detects the voltage of the expansion chip, expansion card and hard disk. Figure 4 As shown, the present invention can use a monitoring module to monitor the power good signal 01 of the front-end electronic fuse (efuse) of the expansion card HBA to detect the power supply of the expansion card HBA card in real time. The present invention can also use a monitoring module to monitor the power good signal 02 of the expansion chip expander power supply. The power good signal 02 can be monitored separately for each voltage, or it can be the power good signal of the last level pushed step by step by the power supply to monitor the power supply status of the expansion chip expander.

[0098] Furthermore, in a specific implementation, the above-mentioned storage system fault monitoring method provided in the embodiment of the present invention may also include: monitoring the signal in each hard disk for detecting the stability of the power supply output voltage, so as to detect the power supply status of each hard disk in real time; and monitoring whether the link between each hard disk and the expansion chip is disconnected, so as to locate the hard disk corresponding to the disconnected link.

[0099] In implementation, the present invention can also use a monitoring module to monitor the power good signal of each hard disk front end efuse to monitor whether each hard disk power supply is abnormal or the hard disk body is short-circuited. Figure 4 As shown, the power good signal 03 of the efuse at the front end of hard disk 1 is monitored to monitor whether the power supply of hard disk 1 is abnormal or the hard disk 1 body is short-circuited; the power good signal 04 of the efuse at the front end of hard disk 2 is monitored to monitor whether the power supply of hard disk 2 is abnormal or the hard disk 2 body is short-circuited; similarly, the power good signal 05 of the efuse at the front end of hard disk n is monitored to monitor whether the power supply of hard disk n is abnormal or the hard disk n body is short-circuited.

[0100] In addition, the present invention can also use a voltage detection module to monitor the hard disk input voltage, further improving the fault location of hard disk drop and other phenomena. The voltage detection module can include an analog to digital converter (ADC) or a voltage comparator.

[0101] Furthermore, in a specific implementation, in the above-mentioned storage system fault monitoring method provided in an embodiment of the present invention, the expansion chip can be connected to the backplane programmable logic device through a general-purpose input / output (GPIO) port; wherein the general-purpose input / output port is a pin with a heartbeat function in the expansion chip.

[0102] Furthermore, in a specific implementation, in the above storage system fault monitoring method provided by an embodiment of the present invention, the expansion chip is connected to the controller via an integrated circuit bus; or, the expansion chip is connected to the controller via a universal asynchronous receiver / transmitter.

[0103] In implementation, the controller can read the register corresponding to the expansion chip expander through the I2C link.
