Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0065] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0066] Currently, the export of SSD device logs mainly uses in-band commands, including custom NVMe Admin commands (Non-Volatile Memory Host Controller Interface Specification) or protocol standard defined Telemetry log acquisition commands, but in actual application, the scenarios that need to export logs often mean that the device or environment has failed, and these failures may affect the sending and processing of custom in-band commands. Therefore, some manufacturers also support the device management function provided by the BMC (Baseboard Management Controller) device platform to obtain the log data of the SSD device. However, the time-consuming of exporting log files through BMC is often in the order of tens of minutes or even hours, which will seriously affect the work efficiency of the operation and maintenance personnel.
[0067] Therefore, the present application provides a log management scheme, which can effectively solve the problems existing in the related schemes in the prior art, thereby efficiently, stably and reliably realizing the log export of the SSD device, and further improving the work efficiency of the operation and maintenance personnel.
[0068] Reference is made to Figure 1As shown, the embodiment of the present application discloses a log management method, applied to a solid state disk device, comprising:
[0069] In the power-on initialization process, the host memory requirement information is reported to the corresponding host, so that the cache allocation is performed by the host based on the received host memory requirement information, and the corresponding cache allocation result is fed back to the solid state disk device.
[0070] In this embodiment, the solid state disk device needs to report the required host memory information to the host, so that the host allocates cache for the solid state disk device accordingly, that is, the solid state disk device is authenticated by the host to determine the authentication result; when the authentication result indicates that the authentication is passed, the host memory requirement information reported by the solid state disk device is received; wherein the host memory requirement information includes the required memory space size information and the host memory cache function; the support capability of the solid state disk device for the host memory cache function is analyzed to determine the function analysis result; based on the function analysis result, it is judged whether the cache request condition is met at present to determine the request condition judgment result; if the request condition judgment result indicates that it is met, the cache allocation is performed in the target memory area based on the memory space size information and the host memory cache function to determine the cache allocation result; wherein the cache allocation result includes the cache base address and the cache size information; the cache allocation result is fed back to the solid state disk device. Wherein, the host should verify the identity of the SSD device, which can be verified by digital certificate or hardware identity number, to ensure that only trusted devices can request memory allocation.
[0071] It should be understood that on the host side, a fixed address and size cache space will be allocated, and the address and size information of the space is notified to the SSD device through a related protocol, such as the host memory cache function of the NVMe protocol, for use by the SSD device. In this scheme, it is used as the target address of the exported log data of the SSD device.
[0072] In addition, when the host allocates memory, it can use reserved memory or dedicated cache area, for example: reserved through UEFI (Unified Extensible Firmware Interface) or related operating system, to avoid being occupied by other application programs. Specifically, a continuous physical address space can be used to optimize the DMA (Direct Memory Access) performance. Moreover, after the host allocates memory, it can set access permissions through IOMMU (Input-Output Memory Management Unit) to ensure that only authorized SSD devices can access the memory area, so as to prevent malicious access or data damage through the memory protection mechanism.
[0073] Step S12, when the log export instruction sent by the host is received by the local out-of-band command processing component, log data reading is performed based on the log export instruction and the local flash memory to determine the log to be exported and the segmented cyclic export strategy.
[0074] In this embodiment, after the cache allocation is completed, until the log export instruction sent by the host is received by the local out-of-band command processing component, the log to be exported and the strategy for exporting the log in the current out-of-band scenario are determined based on the instruction, that is, the log export instruction sent by the host is received by the local out-of-band command processing component of the solid state disk; the log export instruction is parsed by the out-of-band command processing component to determine the length of the target log data to be exported; log data reading is performed based on the out-of-band command processing component, the length of the target log data, and the local flash memory to determine the log to be exported; it is determined whether there is log data of a preset sensitive type in the log to be exported to determine the data determination result; if the data determination result indicates that there is no, it is determined whether the data amount corresponding to the log to be exported is greater than the cache size information to determine the data amount determination result; if the data amount determination result is yes, new host memory requirement information is sent to the host by the solid state disk device and the data amount corresponding to the log to be exported to obtain a new cache allocation result; if the data amount determination result is no, it is determined whether the preset segmented cyclic export condition is met based on the data amount corresponding to the log to be exported to determine the export condition determination result; when the export condition determination result indicates that it is met, the segmented cyclic export strategy corresponding to the log to be exported is determined; wherein, in combination with Figure 2 As shown in the figure, the out-of-band command processing component is located on the side of the solid state disk device, responsible for processing the out-of-band management commands issued by the host side, including the log export command. And cooperate with the log management component, read out the log data located in the persistent storage medium, such as NAND Flash, and transmit it to the specified target address. The segmented cyclic export strategy includes the log segment size information exported each time.
[0075] It can be understood that after the log to be exported is determined, in this embodiment, it is also necessary to detect whether there is sensitive log data in the log, and if there is, the data needs to be encrypted before export to ensure the security of data transmission. And according to the data amount of the log to be exported, it is determined whether it needs to be exported in segments, if not, it can be directly written to the target address by DMA, if it needs to be segmented, the corresponding segmented cyclic export strategy is determined according to the data amount.
[0076] Step S13, using the segmented cyclic export strategy, the log to be exported, the cache allocation result, and the local preset direct memory access engine, the log export operation is completed to obtain the instruction completion information corresponding to the log export instruction.
[0077] In this embodiment, after determining the logs to be exported this time and the related export strategy, the log export is performed in combination with the local preset direct memory access engine, and after the export is completed, the instruction completion information is determined, that is, the segmented cyclic export strategy is used to process the logs to be exported to determine a plurality of log segment sets to be exported; wherein the log segment set includes a plurality of target log segments; based on the local preset direct memory access engine and the cache allocation result, the target address is determined; based on the preset direct memory access engine and the target address, the segmented export of each log segment set is performed in different cyclic rounds respectively, and the preset metadata is added in the head of the target log segment to complete the log export operation and obtain the log export result; the preset metadata is any one or a combination of a plurality of sequence numbers, timestamps and log types; based on the log export result, the instruction completion information corresponding to the log export instruction is determined; and the instruction completion information is sent to the baseboard management controller management component in the host. The solid state disk device writes the exported log data to the specified target address according to the local DMA management component. The baseboard management controller management component is located on the host side and is mainly responsible for the interaction of the out-of-band management command with the solid state disk device to complete the device management function of the BMC platform.
[0078] It can be understood that in the process of segmented cyclic export of logs, metadata such as sequence number, timestamp, log type, etc. can be added in the head of each log segment, so that the host can reorganize and verify according to the metadata.
[0079] Further, in the process of segmented cyclic export of logs in this embodiment, the solid state disk device can also monitor the state of each log segment DMA writing to the target address, and if the writing fails, it will automatically trigger a retry and count, that is, the solid state disk device monitors the log segment export state corresponding to each cyclic round to determine the monitoring result; based on the monitoring result, it is judged whether a log segment export failure event has occurred, to determine the event judgment result; if the time judgment result is yes, the export retry operation corresponding to the corresponding log segment set is triggered, and the current log segment export failure event number and retry number are recorded. The retry number can be pre-set to a corresponding threshold, if the retry number exceeds the threshold, it will not be retried to avoid wasting resources, and related alarm measures are triggered to allow relevant personnel to check and correct in time according to the alarm.
[0080] Step S14, feedback the instruction completion information to the host, so that the host reads the logs from the local memory based on the received instruction completion information, and triggers the log processing operation according to the corresponding log reading result.
[0081] In this embodiment, the obtained instruction completion information is sent to the host, so that after the host receives the information, the log is read and other processing operations are triggered, that is, the substrate management controller management component in the host receives the instruction completion information corresponding to the log export instruction; based on the preset data verification rule and the instruction completion information, the log data is verified to determine the verification result; if the verification result indicates that the verification fails, the corresponding log segment retransmission request operation is triggered based on the verification result; if the verification result indicates that the verification is successful, the local memory of the host is read based on the log export result to determine the log reading result, and the corresponding cache release operation is triggered; the data in the log reading result is transmitted to the path specified by the substrate management controller management component in the form of a log file to trigger a log processing operation.
[0082] It can be understood that in this embodiment, after the host receives the instruction completion information, the integrity and accuracy of the transmitted log can be verified, and if the verification fails, the device is requested to retransmit the missing or erroneous log segment, so as to improve the reliability of the log export.
[0083] Further, in this embodiment, after the host issues the log export instruction to the solid state disk device, based on the preset timeout mechanism, it is determined whether the instruction completion information corresponding to the log export instruction is received within a preset time period to determine a timeout determination result; if the timeout determination result is no, an alarm operation is triggered, and the host reissues the log export instruction to the solid state disk device. It can be understood that in this embodiment, a command timeout mechanism can also be set: if the host does not receive the completion information corresponding to the instruction within a predetermined time after issuing the log export instruction, it is considered as timeout, and the host will resend the instruction and / or trigger an alarm.
[0084] As can be seen from the above, the scheme of this embodiment uses the host memory address as the target address of the log export in the out-of-band scenario, which solves the problem of low data file transmission rate and long transmission time based on the SMBus bus in the traditional BMC channel, and improves the reliability and efficiency of the log export.
[0085] It can be seen that, in the power-on initialization process, the host memory demand information is reported to the corresponding host, so that the host performs cache allocation based on the received host memory demand information, and feeds back the cache allocation result to the solid state disk device, and then when the local out-of-band command processing component receives the log export instruction sent by the host, the log export instruction and the local flash memory log data reading are used to determine the to-be-exported log and the segmented cyclic export strategy. Then, through the local preset direct memory access engine, and using the segmented cyclic export strategy, the to-be-exported log, and the cache allocation result, the log export operation is completed, the log export result is obtained, and then the instruction completion information is fed back to the host, so that the host performs log reading on the local memory of the host based on the received instruction completion information, and triggers the log processing operation. In this way, the problems existing in the prior related scheme can be effectively solved, so that the log export of the SSD device is efficiently, stably and reliably realized, and the work efficiency of the operation and maintenance personnel is improved.
[0086] The technical solutions of the embodiments of the present application will be described in detail below in combination with the timing diagram disclosed in the present application. Figure 3
[0087] In the present embodiment, system initialization is first performed, and during the initialization, the SSD device reports the required host memory address capability and the information of the required space size to the Host (host). Then, the Host queries the support capability of the SSD device for the host memory cache function, and if it is determined that the device is supported, the cache is applied according to the information reported by the SSD device, and the base address and size information of the applied cache are notified to the SSD device. After receiving the cache address A and length information L issued by the Host, the SSD device will record them as the target address and size for subsequent log data export.
[0088] Further, the present embodiment also includes a corresponding log generation process, in which the solid state disk device is run, and the log information generated during the running process is cached to the buffer area (Buffer) inside the device, and then the solid state disk device flushes the log of the buffer area to the flash memory (NAND flash).
[0089] Afterwards, in the log export process, the Host sends a log export command to the SSD device through the BMC management component. After receiving the log export command, the SSD device parses the data length of the log to be exported, reads the log from the persistent storage medium, i.e., the NAND flash, to the local cache, and writes the log data in the local cache. Furthermore, the export strategy is formulated, and the SSD device can select the cyclic multiple times and segmented export mode, fixedly export a specified size L1 of log data at a time, and write the exported log data to the addresses A, A+L1, A+L2, … in multiple steps through the DMA engine.
[0090] After the SSD device completes writing all the log data to be exported to the target address (i.e., the host memory address), the completion information of the log export command received in the foregoing step is returned to the BMC management component of the Host. Afterwards, the Host receives the completion information through the component, reads all the log information from the host memory address according to the completion information, and outputs the log information in the form of a log file to a specified path of the BMC platform for the operation and maintenance personnel to obtain and use.
[0091] In this way, the rate of transmitting the log file using this mode can reach the order of GB / S, which is several orders of magnitude higher than the rate of 100 Kbps based on the traditional SMBus bus, and the acquisition of the log file in the out-of-band channel within one second is realized, greatly improving the work efficiency of the operation and maintenance personnel.
[0092] Referring to Figure 4 The embodiment of the application also discloses a log management device applied to a solid state disk device, which comprises:
[0093] The cache allocation module 11 is configured to report host memory demand information to the corresponding host in the power-on initialization process, so that the host performs cache allocation based on the received host memory demand information, and feeds back the corresponding cache allocation result to the solid state disk device.
[0094] The export strategy determination module 12 is configured to, when receiving the log export instruction sent by the host through the local out-of-band command processing component, perform log data reading based on the log export instruction and the local flash memory, so as to determine the log to be exported and the segmented cyclic export strategy.
[0095] The log export module 13 is configured to complete the log export operation by using the segmented cyclic export strategy, the log to be exported, the cache allocation result and the local preset direct memory access engine, so as to obtain the instruction completion information corresponding to the log export instruction.
[0096] The log reading module 14 is configured to feed back instruction completion information to the host, so that the host performs log reading on the local memory of the host based on the received instruction completion information, and triggers a log processing operation according to a corresponding log reading result.
[0097] It can be seen that, in the power-on initialization process, the host memory requirement information is reported to the corresponding host, so that the host performs cache allocation based on the received host memory requirement information, and feeds back the cache allocation result to the solid state disk device, and then when the local out-of-band command processing component receives the log export instruction sent by the host, the log data reading is read based on the log export instruction and the local flash memory, to determine the to-be-exported log and the segmented cyclic export strategy. Then, the log export operation is completed by the local preset direct memory access engine, and the segmented cyclic export strategy, the to-be-exported log and the cache allocation result are used to obtain the log export result, and then the instruction completion information is fed back to the host, so that the host performs log reading on the local memory of the host based on the received instruction completion information, and triggers a log processing operation. In this way, the problems existing in the prior related solutions can be effectively solved, so that the log export of the SSD device is efficiently, stably and reliably realized, and the work efficiency of the operation and maintenance personnel is improved.
