Description

Technical Field

[0001] This invention relates to the field of solid-state drive out-of-band management storage technology, and in particular to a testing and verification method and apparatus for SSD SMBUS temperature alarm and low power consumption status. Background Technology

[0002] SMBUS (System Management Bus) is a communication management mechanism developed based on the I2C (Inter-Integrated Circuit) protocol for low-speed, high-stability scenarios. Its system management bus primarily uses two signal lines for data transmission and communication: SMCLK (SMBUS clock) and SMDAT (SMBUS Data). Even when in-band signal anomalies prevent the normal reading of SSD information and temperature, the health status of the SSD can still be monitored in real time via out-of-band SMBUS signals, such as obtaining SSD power consumption, device information, and temperature. The BIOS (Basic Input Output System) adjusts fan speed based on the acquired temperature to optimize the overall system acoustics. In computers with mass-produced SSDs, the SMBUS out-of-band signal access mechanism will significantly improve computer maintenance efficiency and reduce maintenance costs. Therefore, testing whether the SSD can read SSD temperature, device information, and temperature alarms in normal and low-power modes after enabling SMBUS is crucial. If a solid-state drive (SSD) that supports SMBUS cannot read the SSD temperature in normal or low-power mode, or if the temperature alarm mechanism fails, it will miss the best opportunity to handle the fault, greatly affecting the user's experience and trust in the SSD product.

[0003] Currently, server platforms do not support low-power SSD functionality. Only desktops and laptops support SSD low-power, but no computers with SMBUS-enabled M.2 SSD interfaces have been released on the market. ULINK's Driver Master software and its accompanying PSPA (PCIe SSD Power Adaptor) hardware lack physical SMBUS wiring, and SMBUS testing commands are not yet fully developed. SANBLAZE's server-specific SSD testing suite also does not support low-power mode. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a testing and verification method and device for SSD SMBUS temperature alarm and low power consumption state.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Firstly, this embodiment provides a testing and verification method for SSD SMBUS temperature alarm and low power consumption state, including the following steps:

[0007] Read information from the solid-state drive;

[0008] Determine if the VID and DID in the solid-state drive's information match the preset settings;

[0009] If the settings are met, the status of the solid-state drive is read.

[0010] Determine if the SMART Warning status of the solid-state drive is FFh;

[0011] If SMART Warning is FFh, then record the current composite temperature value of the solid-state drive;

[0012] Write data to the solid-state drive;

[0013] Determine if the current synthesis temperature of the solid-state drive is greater than the set threshold.

[0014] If the value exceeds the set threshold, data writing to the solid-state drive will be stopped.

[0015] Read the status of the solid-state drive;

[0016] Determine if the SMART Warning status of the solid-state drive is DFh;

[0017] If SMART Warning is DFh, it means that the temperature alarm event was successfully triggered, and the current composite temperature value of the solid-state drive is recorded.

[0018] Turn off the automatic power state transition function of the solid-state drive and set the solid-state drive to a low power state;

[0019] Determine if the power status of the solid-state drive is in a low-power state;

[0020] If the power state is low power, determine whether SMBUS can respond normally and return hard disk information;

[0021] If SMBUS can respond normally and return hard disk information, it means that SMBUS is operating normally in a low-power state.

[0022] The further technical solution is as follows: before the step of reading the information of the solid-state drive, it also includes: checking whether the solid-state drive controller data structure supports SMBUS; if it supports SMBUS, then the SMBUS function is enabled.

[0023] The further technical solution is as follows: after the step of determining whether the SMART Warning in the state of the solid-state drive is FFh, it also includes: if the SMART Warning is not FFh, it indicates that a temperature alarm event has been detected, and the current composite temperature value of the solid-state drive is recorded.

[0024] The further technical solution is as follows: after the step of determining whether the current synthesis temperature value of the solid-state drive is greater than the set threshold, it also includes: if it is not greater than the set threshold, then continue to write data to the solid-state drive for 5 minutes, and then determine whether the current synthesis temperature value of the solid-state drive is greater than the set threshold. If it is still not greater than the set threshold, it indicates that the temperature sensor has malfunctioned.

[0025] Secondly, this embodiment provides a test and verification device for SSD SMBUS temperature alarm and low power consumption state, including: a first reading unit, a first judgment unit, a second reading unit, a second judgment unit, a recording unit, a writing unit, a third judgment unit, a stop unit, a third reading unit, a fourth judgment unit, a trigger recording unit, a shutdown setting unit, a fifth judgment unit, a sixth judgment unit, and a running unit.

[0026] The first reading unit is used to read information from the solid-state drive;

[0027] The first judgment unit is used to determine whether the VID and DID in the information of the solid-state drive conform to the preset settings;

[0028] The second reading unit is used to read the status of the solid-state drive if it meets the preset settings;

[0029] The second judgment unit is used to determine whether the SMART Warning status of the solid-state drive is FFh;

[0030] The recording unit is used to record the current composite temperature value of the solid-state drive if the SMART Warning is FFh.

[0031] The writing unit is used to write data to the solid-state drive;

[0032] The third judgment unit is used to determine whether the current synthesis temperature value of the solid-state drive is greater than the set threshold.

[0033] The stop unit is used to stop writing data to the solid-state drive if the value exceeds a set threshold.

[0034] The third reading unit is used to read the status of the solid-state drive;

[0035] The fourth judgment unit is used to determine whether the SMART Warning status of the solid-state drive is DFh.

[0036] The trigger recording unit is used to record the current composite temperature value of the solid-state drive if the SMART Warning is DFh, indicating that the temperature alarm event has been successfully triggered.

[0037] The shutdown setting unit is used to disable the automatic power state transition function of the solid-state drive and set the solid-state drive to a low-power state.

[0038] The fifth judgment unit is used to determine whether the power state of the solid-state drive is a low-power state.

[0039] The sixth judgment unit is used to determine whether SMBUS can respond normally and return hard disk information if the power state is a low power state.

[0040] The operating unit is configured to indicate that SMBUS is operating normally in a low-power state if SMBUS can respond normally and return hard disk information.

[0041] The further technical solution includes: a checking unit for checking whether the solid-state drive controller data structure supports SMBUS; if SMBUS is supported, the SMBUS function is enabled.

[0042] The further technical solution includes: a check recording unit, which is used to record the current composite temperature value of the solid-state drive if the SMART Warning is not FFh, indicating that a temperature alarm event has been detected.

[0043] The further technical solution includes: a write judgment unit, which is used to continue writing data to the solid-state drive for 5 minutes if the value is not greater than the set threshold, and then judge whether the current composite temperature value of the solid-state drive is greater than the set threshold. If it is still not greater than the set threshold, it indicates that the temperature sensor has failed.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0055] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0056] Please see Figure 1 The specific embodiment shown in this invention discloses a testing and verification method for SSD SMBUS temperature alarm and low power consumption state, including the following steps:

[0057] The testing environment for this method is as follows: Computer under test: Lenovo X1 Carbon 9th laptop; Note: This method is suitable for low-power laptops and desktops, but the specific model is not mandatory. The Lenovo X1 Carbon 9th laptop is preferred as the computer under test. Solid-state drive under test: M.2 solid-state drive supporting the SMBUS protocol. Software requirements: Operating system: Linux Ubuntu 20.04; Testing tool: NVME-cli; Testing script: Shell testing script.

[0058] S1, reads information from the solid-state drive;

[0059] Before step S1, the test also includes: checking whether the solid-state drive controller data structure supports SMBUS; if SMBUS is supported, enabling the SMBUS function through the NVME set-feature command; if SMBUS is not supported, exiting the test.

[0060] Specifically, check if the first position (solid-state drive controller data structure) in byte 4004 supports SMBUS; if the first position is 1, then SMBUS is supported and the SMBUS function can be enabled.

[0061] Specifically, in step S1, the SMBUS write command format in Table 1 is used to first send the SMBUS write command to address D4h, then send the command code 08h (representing reading information from the solid-state drive), and finally send the read command to address D5h to obtain the solid-state drive information returned by the solid-state drive through SMBUS.

[0062] Table 1

[0063]

[0064] S2 checks whether the VID and DID in the solid-state drive information match the preset settings; if they do not match the preset settings, the solid-state drive is recorded as faulty.

[0065] Wherein, VID stands for Vendor Identifier, and DID stands for Device Identifier. The default values ​​are VID = 0x1CC4 and DID = 0x06A0.

[0066] S3, if it meets the preset settings, reads the status of the solid-state drive;

[0067] Specifically, in step S3, command code 00 is sent via SMBUS basic management commands to read the status of the solid-state drive.

[0068] The basic management commands here have the same format as the management commands above.

[0069] S4, determine if the SMART Warning status of the solid-state drive is FFh;

[0070] Among them, SMART stands for Self-Monitoring Analysis and Reporting Technology; Warning is an alarm byte; FFh indicates that no temperature alarm event has occurred.

[0071] Following step S4, the process includes: if SMART Warning is not FFh, it indicates a temperature alarm event has been detected, and the current composite temperature value of the SSD is recorded. Upon receiving this temperature alarm, the BIOS will increase the fan speed to cool the SSD, allowing it to quickly return to optimal performance.

[0072] S5, if SMART Warning is FFh, then record the current synthesis temperature value of the solid-state drive;

[0073] S6, writes data to the solid-state drive;

[0074] Specifically, in step S6, data is written to the solid-state drive using the NVME write command.

[0075] S7, determine whether the current synthesis temperature of the solid-state drive is greater than the set threshold;

[0076] Prior to step S7, the method includes setting a temperature alarm threshold using the NVME set-feature command. Specifically, in this embodiment, the temperature alarm threshold is set to 40 degrees or 45 degrees.

[0077] The process includes the following steps after step S7: if the temperature is not greater than the set threshold, continue writing data to the solid-state drive for 5 minutes, and then determine whether the current combined temperature value of the solid-state drive is greater than the set threshold. If it is still not greater than the set threshold, it indicates that the temperature sensor has malfunctioned. If it is greater than the set threshold, the temperature alarm trigger condition is met, and the SMARTwarning byte can be read.

[0078] S8, if the value exceeds the set threshold, stop writing data to the solid-state drive;

[0079] Specifically, in step S8, the NVME write command is stopped from writing data to the solid-state drive.

[0080] S9 reads the status of the solid-state drive;

[0081] Specifically, in step S9, command code 00 is sent via SMBUS basic management commands to read the status of the solid-state drive.

[0082] S10, determine if the SMART Warning status of the solid-state drive is DFh;

[0083] Among them, DFh: A temperature alarm event occurred.

[0084] The steps following S10 include: if SMART Warning is not DFh, record the temperature alarm verification failure and record the current synthesized temperature value of the solid-state drive.

[0085] S11, if SMART Warning is DFh, it means that the temperature alarm event was successfully triggered, and the current composite temperature value of the solid-state drive is recorded.

[0086] S12, disable the automatic power state transition function of the solid-state drive and set the solid-state drive to a low power state;

[0087] S13, determine whether the power state of the solid-state drive is in a low-power state; if the power state is not in a low-power state, record that the solid-state drive is faulty and fail to enter the low-power state.

[0088] S14. If the power state is low power, determine whether SMBUS can respond normally and return hard disk information; if SMBUS cannot respond normally and return hard disk information, record that the solid-state drive is faulty, or that there is an SMBUS problem in the low power state. An SMBUS problem means that SMBUS cannot work.

[0089] S15. If SMBUS can respond normally and return hard disk information, it means that SMBUS is operating normally in a low-power state.

[0090] This invention can quickly and efficiently verify the SMBUS out-of-band management functions of solid-state drives, such as SMBUS reading of solid-state drive status and information, temperature alarm mechanism, and problems such as the inability to access SMBUS under low power PS3, and can better meet the needs.
