Technical Field

[0001] This invention belongs to the field of server hard disk testing technology, and in particular relates to a testing system and method for testing the power-on time of NVMe hard disks. Background Technology

[0002] The server hard drive is one of the most critical components of a server. Therefore, testing server hard drives is essential to understand their physical condition, performance, and data read / write capabilities. Physical condition testing includes checking the hard drive's circuit board, electronic components, and disk surface to ensure there are no obvious damages, cracks, or impact marks. These checks are to ensure the hard drive is free from physical damage, as even minor damage can affect its normal operation and lifespan. Performance testing includes data read / write speeds and seek times. Compatibility and stability testing is also conducted to ensure the hard drive's compatibility with the server system and its stability under prolonged operation. This includes multiple power-on / off tests and long-term read / write tests to verify the hard drive's ability to operate stably under various working conditions.

[0003] Server hard drive testing also includes an important aspect: testing the power-on time of the hard drive. However, current technology requires specialized equipment to test the power-on time of server hard drives, and this equipment is expensive, resulting in high testing costs.

[0004] Therefore, how to improve the existing power-on time detection method in server hard drive testing so as to test the power-on time of the hard drive without the need for professional instruments, thereby reducing the cost of server hard drive testing, is a technical problem that urgently needs to be solved.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A testing system for testing the power-on time of an NVMe hard drive includes a PCIe state machine, a logging module, a log analysis module, and a power-on time analysis module. The PCIe state machine is equipped with a command sending module, which is connected to the logging module. The logging module is also connected to the log analysis module.

[0008] It also includes a clock circuit module, which is electrically connected to the PCIe state machine;

[0009] The PCIe state machine is used to represent the state of the PCIe device interface and the transition data;

[0010] The command sending module is used to continuously send ICMP echo request data to the server host and continuously wait for the host to return an ICMP echo response.

[0011] The logging module is used to record all logs in the PCIe state machine;

Then, it represents each information string as a vector according to the dimensions that make up the feature vector, and then extracts the logs of sending ICMP echo request data and the host returning ICMP echo response from the log information.

[0027] Preferably, the power-on time analysis module obtains the log of the PCIe state machine being in state L0 based on the extracted ICMP echo request data and the log of the host returning ICMP echo response, thereby obtaining the log record of the hard disk power-on time point, and obtaining the corresponding hard disk power-on time based on the log record and the clock circuit.

[0028] Secondly, a method for testing the power-on time of an NVMe hard drive is provided, based on a testing system for testing the power-on time of an NVMe hard drive as described in any one of the claims, including the following steps:

[0034] Preferably, the specific process in step S3 is as follows:

[0035] S31: The log file acquisition module retrieves log files from the specified server and path. By configuring the address of the test environment server and the execution log storage path, when the program or script is executed, it retrieves the log file from the specified path on the specified server, saves it to the local machine, and passes it to the tool for processing.

[0036] S32: Log text parsing and keyword extraction module, which parses the execution result log, extracts the text content according to the encoding format of the log text, extracts the information into log information strings, extracts text keywords as feature words according to the set feature value labels, and represents each information string as a vector form according to the various dimensions that make up the feature vector, and then extracts the logs of sending ICMP echo request data and host returning ICMP echo response from the log information.

[0037] The beneficial effects of this invention include:

[0038] The present invention provides a testing system and method for testing the power-on time of an NVMe hard drive, comprising a PCIe state machine, a log recording module, a log analysis module, and a power-on time analysis module. The PCIe state machine includes a command sending module connected to the log recording module, which in turn is connected to the log analysis module. It also includes a clock circuit module electrically connected to the PCIe state machine. The PCIe state machine represents the state of the PCIe device interface and transmits transition data. The command sending module continuously sends ICMP echo request data to the server host and waits for the host to return an ICMP echo response. The log recording module records all logs in the PCIe state machine. The log analysis module analyzes all logs generated by the PCIe state machine and determines the working status of the communication link of the PCIe state machine. The clock circuit generates and provides a precise and stable clock signal. The power-on time analysis module obtains the corresponding log record for the hard drive power-on time based on the log analysis results, and obtains the corresponding hard drive power-on time based on the log record and the clock circuit.

[0039] First, by setting up a PCIe state machine that includes a command sending module, ICMP echo request data is continuously sent to the server host from the start of server startup, and the host is continuously waited for an ICMP echo response. All logs are recorded by the logging module, and then the log analysis module parses the logs and extracts the logs of sending ICMP echo request data and the host's ICMP echo response, thereby obtaining the logs of the L0 state of the PCIe state machine. The whole process is simple and fast.

[0040] Secondly, by acquiring the log of the PCIe state machine L0 state, and combining it with a clock circuit to generate and provide a precise and stable clock signal, the corresponding time in the PCIe state machine L0 state log is obtained, which is the power-on time of the NVMe hard drive.

Detailed Implementation

[0045] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in detail below:

[0046] Example 1

[0047] See appendix Figure 1 As shown, a test system for testing the power-on time of an NVMe hard drive includes a PCIe state machine, a logging module, a log analysis module, a clock circuit module, and a power-on time analysis module. The PCIe state machine includes a command sending module connected to the logging module, which in turn is connected to the log analysis module. The clock circuit is electrically connected to the PCIe state machine. The PCIe state machine represents the state of the PCIe device interface and transmits transition data. The command sending module continuously sends ICMP echo request data to the server host and waits for the host to return an ICMP echo response. The logging module records all logs from the PCIe state machine. The log analysis module analyzes all logs generated by the PCIe state machine and determines the working status of the communication link of the PCIe state machine. The clock circuit generates and provides a precise and stable clock signal. The power-on time analysis module obtains the corresponding log records for the hard drive power-on time based on the log analysis results and uses the log records and the clock circuit to obtain the corresponding hard drive power-on time.

[0048] By configuring a PCIe state machine including a command sending module, ICMP echo request data is continuously sent to the server host from the start of server startup, and the system continuously waits for the host to return ICMP echo responses. A logging module records all logs, and a log analysis module parses the logs, extracting the logs of sent ICMP echo request data and the host's returned ICMP echo responses, thus obtaining the log of the PCIe state machine's L0 state. The entire process is simple and fast. After obtaining the log of the PCIe state machine's L0 state, a clock circuit generates and provides a precise and stable clock signal to obtain the corresponding time in the PCIe state machine's L0 state log, which is the power-on time of the NVMe hard drive. Therefore, this invention, by configuring a PCIe state machine including a command sending module and combining it with a clock circuit to measure the power-on time of the NVMe hard drive, avoids the need for specialized instruments to test the power-on time of the NVMe hard drive, reducing the testing cost of server NVMe hard drives.

One end of the inductor L is connected to the power output terminal, and the other end is connected to the first capacitor C1. The VCC port of the first chip U1 is connected to the first capacitor C1 and the second capacitor C2, which are connected in parallel and grounded. Both the first capacitor C1 and the second capacitor C2 are connected to the SCLK port of the second chip U2. The X port of the second chip U2 is connected to the third capacitor C3, and the other end of the third capacitor C3 is grounded. The RFOUT port of the second chip U2 is connected to the fourth capacitor C4. The OUT port of the first chip U1 is connected to the RFIN port of the second chip U2. The GND port of the second chip U2 is grounded, and the GND port of the first chip U2 is also grounded. The voltage output by the power output terminal is 3.3V. One end of the crystal oscillator G is connected to the X port of the second chip U2 and the third capacitor C3, respectively, and the other end is connected to the RFINOUT port of the second chip U2 and the fourth capacitor C4, respectively.

[0051] When the circuit is working, it generates a stable frequency oscillation signal through the crystal resonance effect of the crystal oscillator G. Based on the stable frequency oscillation signal, it provides a precise and stable clock signal, providing a precise time reference for the system.

[0052] The command sending module includes a command routing and scheduling module, a Windows PowerShell module, and an Ansible module. The command routing and scheduling module is used to build a command routing and scheduling mechanism based on Windows' message processing mechanism. It handles various user interface events through command IDs and associates command IDs with corresponding processing functions through message mapping. The Windows PowerShell module provides a command-line shell and scripting environment, allowing system management through scripts or direct command input, including file operations, service management, and system status checks. The Ansible module is used to execute remote management tasks, remote commands, manage users and groups, and schedule tasks.

[0053] Example 3

[0054] Based on Embodiment 1 or Embodiment 2, the log analysis module includes a log file acquisition module and a log text parsing and keyword extraction module, with the log file acquisition module connected to the log text parsing and keyword extraction module. The log file acquisition module retrieves log files from a specified server and path. These log files originate from program execution or batch script execution within the project, have a centralized storage path, and a unified log name format. By configuring the address of the test environment server and the execution log storage path, after the program or script is executed, the log file is retrieved from the specified path on the specified server, stored locally, and then transferred to the tool for processing. The log text parsing and keyword extraction module parses the execution result logs. Log files are typically large and complex, requiring parsing to extract useful information. This module extracts the text content according to the log text's encoding format, breaking the information down into individual log information strings. Based on set feature value tags, it extracts text keywords as feature terms and represents each information string as a vector according to the dimensions that make up the feature vector. This allows the extraction of logs containing ICMP echo request data and host-returned ICMP echo responses.

[0055] In this embodiment, the power-on time analysis module obtains the log of the PCIe state machine being in state L0 based on the extracted ICMP echo request data and the log of the host returning ICMP echo response, thereby obtaining the log record of the hard disk power-on time. Based on the log record, it obtains the accurate time reference provided by the log and the clock circuit, and then obtains the accurate power-on time of the corresponding hard disk.

[0056] A method for testing the power-on time of an NVMe hard drive, implemented based on any one of the testing systems for testing the power-on time of an NVMe hard drive, includes the following steps:

[0057] S1: Start the server and continuously send ICMP echo request data to the server host through the command sending module in the PCIe state machine, and continuously wait for the host to return an ICMP echo response. Since the power-on time of the NVMe hard drive can be determined by the L0 state of the PCIe state machine, that is, when the PCIe state machine is in the L0 state, it can be determined that the NVMe hard drive has successfully powered on. The PCIe state machine being in the L0 state indicates that the communication link of the PCIe state machine is in a normal working state. Therefore, by continuously sending ICMP echo request data to the server host through the command sending module in the PCIe state machine and waiting for the host to return an ICMP echo response, when the command sending module in the PCIe state machine can successfully send ICMP echo request data to the server host and the host returns an ICMP echo response, it indicates that the communication link of the PCIe state machine is in a normal working state, that is, the NVMe hard drive has successfully powered on. This point in time is the NVMe hard drive power-on time.

[0058] S2: The logging module records all server logs after the server starts and transmits them to the log analysis module. The logging module records all server logs to obtain logs of ICMP echo request data sent by the command sending module to the server host and logs of ICMP echo responses returned by the host. This facilitates the subsequent parsing of the obtained log information by the log analysis module, and allows it to extract the logs of sent ICMP echo request data and returned ICMP echo responses.

[0059] S3: The log analysis module parses the acquired log information and extracts the logs of sent ICMP echo request data and host returned ICMP echo responses. By extracting the logs of sent ICMP echo request data and host returned ICMP echo responses, the clock circuit module can subsequently obtain the time of the corresponding ICMP echo request data sent and the host returned ICMP echo responses.

[0060] S4: The power-on time analysis module obtains the log of the PCIe state machine in state L0 based on the extracted ICMP echo request data and the host's returned ICMP echo response log, obtains the log record of the hard disk power-on time, and obtains the corresponding hard disk power-on time based on the log record and the log and clock circuit module.

[0061] S5: Outputs hard drive power-on time.

[0062] The specific process in step S3 is as follows:

[0063] S31: The log file acquisition module retrieves log files from the specified server and path. By configuring the address of the test environment server and the execution log storage path, when the program or script is executed, it retrieves the log file from the specified path on the specified server, saves it to the local machine, and passes it to the tool for processing.

[0064] S32: Log text parsing and keyword extraction module, which parses the execution result log, extracts the text content according to the encoding format of the log text, extracts the information into log information strings, extracts text keywords as feature words according to the set feature value labels, and represents each information string as a vector form according to the various dimensions that make up the feature vector, and then extracts the logs of sending ICMP echo request data and host returning ICMP echo response from the log information.

[0065] In summary, the testing system and method for testing the power-on time of an NVMe hard drive provided by this invention includes a PCIe state machine, a log recording module, a log analysis module, and a power-on time analysis module. The PCIe state machine includes a command sending module connected to the log recording module, which in turn is connected to the log analysis module. It also includes a clock circuit module electrically connected to the PCIe state machine. The PCIe state machine represents the state of the PCIe device interface and transmits transition data. The command sending module continuously sends ICMP echo request data to the server host and waits for the host to return an ICMP echo response. The log recording module records all logs in the PCIe state machine. The log analysis module analyzes all logs generated by the PCIe state machine and determines the working status of the communication link of the PCIe state machine. The clock circuit generates and provides a precise and stable clock signal. The power-on time analysis module obtains the corresponding log record for the hard drive power-on time based on the log analysis results and obtains the corresponding hard drive power-on time based on the log record and the clock circuit.

[0066] By configuring a PCIe state machine that includes a command sending module, ICMP echo request data is continuously sent to the server host from the start of server startup, and the system continuously waits for the host to return ICMP echo responses. In conjunction with the logging module, all logs are recorded, and then the log analysis module parses the logs and extracts the logs of sent ICMP echo request data and the host's returned ICMP echo responses, thereby obtaining the logs of the PCIe state machine L0 state. The whole process is simple and fast.

[0067] After obtaining the log of the PCIe state machine L0 state, and combining it with a clock circuit to generate and provide a precise and stable clock signal, the corresponding time in the PCIe state machine L0 state log is obtained, which is the power-on time of the NVMe hard drive. Therefore, this invention, by setting up a PCIe state machine including a command sending module and combining it with a clock circuit to measure the power-on time of the NVMe hard drive, avoids the need to test the power-on time of the NVMe hard drive with professional instruments, thus reducing the testing cost of server NVMe hard drives.
