Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, equipment and computer-readable storage medium for processing fault information of a solid state drive. Background Art

[0002] SSD, also known as solid-state drive, is a hard disk made of solid-state electronic storage chip array. During the use of SSD and the development of its firmware, when a fault occurs, it is necessary to save the fault scene. Some critical fault information is stored in the register. If the SSD is powered off due to force majeure before the problem is located, some information in the register that helps analyze the cause of the fault will be lost. In this case, the problem can only be reproduced by analyzing the usage scenario.

[0003] Take the read operation of a solid-state drive as an example. When a fault occurs during the read operation of a solid-state drive, the channel where the problem occurs is usually determined first, and the relevant information of the context in which the problem occurs is saved in the register. The relevant information in the register needs to be exported to the DDR (Double Data Rate SDRAM, double-rate synchronous dynamic random access memory), and then the DDR is read and the relevant information is analyzed to locate the cause of the fault. However, if a power failure occurs before or after the information is imported into the DDR, and before the content in the DDR is read for fault analysis, the useful information used to analyze the cause of the fault will be lost, making it impossible to reproduce the fault, which greatly reduces the efficiency of fault location.

[0004] In view of this, how to prevent the loss of relevant information used to analyze the cause of the fault and improve the efficiency of fault location is a problem that technical personnel in this field need to solve. Summary of the invention

[0020] When a context switch is detected, the first timer is reset to a second preset duration and starts counting down.

[0027] Another aspect of the present invention provides a fault information processing device for a solid state drive, comprising:

[0036] It can be seen from the above technical solution that the beneficial effects of the present invention are:

[0037] An embodiment of the present invention provides a method for processing fault information of a solid-state hard disk, comprising: when it is identified that the fault type for a current read / write operation request is a preset fault type, determining whether there is a completion message returned to a flash memory conversion layer within a first preset time length; if there is a completion message returned to the flash memory conversion layer within the first preset time length, determining a target register and a target storage area in a double-rate synchronous dynamic random access memory according to the current read / write operation request, and adding fault field information to the completion message; the fault field information is used to determine a fault channel; triggering the target register to interrupt the current operation, and importing the fault information in the target register into the target storage area; returning the completion message with the added fault field information to the flash memory conversion layer, and writing the fault information in the target storage area into a non-volatile memory through other normal channels based on a write request returned by the flash memory conversion layer, the write request being a message generated by the flash memory conversion layer for other channels except the fault channel based on the completion message.

[0038] It can be seen that in the embodiment of the present invention, when the flash channel controller identifies that the fault type is a preset fault type, if a completion message can be returned to the flash conversion layer within the first preset time period to indicate that the context is not stuck, the fault field information can be added to the completion message, and the corresponding register is triggered to interrupt the current operation, and the key variable value related to the context in the register (that is, the fault information) is imported into the target storage area corresponding to the fault channel in the double-speed synchronous dynamic random access memory, and the completion message is returned to the flash conversion layer. The flash conversion layer sends a write request for other normal channels except the fault channel to the flash channel controller according to the completion message. The flash channel controller can flush the fault data imported into the target storage area in the double-speed synchronous dynamic random access memory to the non-volatile memory through other normal channels according to the write request. Since the data in the non-volatile memory will not be lost due to power failure, storing the fault data through the non-volatile memory can better prevent data loss and ensure data security. When locating the fault, the fault data can be directly obtained from the non-volatile memory, which is conducive to improving the efficiency of fault locating.

[0039] In addition, the present invention also provides a corresponding implementation device and a computer-readable storage medium for the fault information processing method of the solid-state hard disk, which further makes the method more practical, and the device and the computer-readable storage medium have corresponding advantages.

[0046] 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.

[0047] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0048] 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.

[0049] Next, a method for processing fault information of a solid state drive provided by an embodiment of the present invention is described in detail. Figure 1 A flowchart of a method for processing fault information of a solid state drive provided by an embodiment of the present invention, the method comprising:

[0050] S110: When it is identified that the fault type for the current read / write operation request is a preset fault type, determining whether there is a completion message returned to the flash translation layer within a first preset time period;

[0051] It should be noted that the method provided in the embodiment of the present invention can be applied to a flash channel controller (FCC) of a solid-state hard disk. When performing read and write operations, the flash channel controller can identify the processing status of the current read and write operation request. When a fault is identified, the fault type is identified. If the fault type is a preset fault type, it is further determined whether the flash channel controller has a context stuck. That is, it can be determined whether the context is stuck by judging whether a completion message is returned to the flash translation layer within a first preset time length. If the flash channel controller returns a completion message to the flash translation layer (FTL) within the first preset time length, it means that the context of the flash channel controller is not stuck. If the flash channel controller has not returned a completion message to the flash translation layer within the first preset time length, it can be determined that the context of the flash channel controller has been stuck.

[0052] The preset fault type in the embodiment of the present invention is a write fault type or other read fault types except the type of the number of error bits being higher than the threshold value. That is, for any write operation request, when a fault is identified, no matter which write fault type it is, it meets the situation of the preset fault type. For a read operation request, when a fault is identified, if the fault type is not the type of the number of error bits being higher than the threshold value (that is, the number of error bits is too high), it meets the situation of the preset fault type.

[0053] S120: If there is a completion message returned to the flash translation layer within the first preset time, determine the target register and the target storage area in the double data rate synchronous dynamic random access memory according to the current read and write operation request, and add fault field information to the completion message; the fault field information is used to determine the fault channel;

[0054] It can be understood that if the flash channel controller returns a completion message to the flash conversion layer within the first preset time length, the fault channel can be further located according to the current read and write operation request, that is, it can be determined which channel has a problem. After the fault channel is determined, the corresponding target register and the target storage area corresponding to the fault channel in the double-rate synchronous dynamic random access memory DDR can be further determined according to the fault channel, and the fault field information is added to the completion message, that is, the fault field information is assigned to the completion message, wherein the fault field information is used to determine the fault channel, and the fault field information may include one or more of the fault channel, target register and target storage area, and may also include the fault type. Of course, the fault field information may also include a fault import flag, which is used to indicate whether fault information has been imported into the DDR, and the fault import flag can be set after the fault information is imported into the target storage area in the DDR.

[0055] In practical applications, a mapping relationship between channels and registers can be established in advance, and a mapping relationship between channels and storage areas in DDR can be established. After locating the faulty channel according to the current read and write operation request, the target register corresponding to the faulty channel can be further determined based on the faulty channel combined with the mapping relationship between the channel and the register, and the target storage area corresponding to the faulty channel can be determined based on the faulty channel combined with the mapping relationship between the channel and the DDR storage area.

[0056] It is understandable that a mapping relationship between the channel value and the starting address in the DDR can also be established, so that after the faulty channel is determined, the starting address of the corresponding storage area in the DDR can be further determined according to the value of the faulty channel.

[0057] S130: Trigger the target register to interrupt the current operation, and import the fault information in the target register into the target storage area;

[0058] It should be noted that after the fault type field is added, the interrupt of the target register will be triggered immediately, causing the target register to interrupt the current operation. Then, the value of the context-related key variable on the target register (that is, the fault information) is imported into the target storage area on the DDR.

[0059] S140: Return the completion message after adding the fault field information to the flash translation layer, and write the fault information in the target storage area into the non-volatile memory through other normal channels except the fault channel based on the write request returned by the flash translation layer; wherein the write request is a message generated by the flash translation layer for other channels except the fault channel based on the completion message.

[0060] It should be noted that in the embodiment of the present invention, after the fault field information is added to the completion message, the completion information is returned to the upper flash conversion layer, and the fault channel can be determined based on the fault field information in the completion message, and the fault import flag is identified in the detected fault field information, and when it is determined that fault information has been imported into the DDR, a write request is generated for other normal channels except the fault channel, and then the write request is returned to the flash channel controller. After receiving the write request, the flash channel controller writes the fault information that has been imported into the target storage area of ​​the double-rate synchronous dynamic random access memory into the non-volatile memory through other normal channels except the fault channel according to the write request, thereby preventing the fault information from being lost due to power failure.

[0061] That is, in the embodiment of the present invention, the fault information can be saved in the non-volatile memory as soon as the fault occurs, thereby avoiding the loss of fault information due to abnormal power failure, which is beneficial to improving the efficiency of fault analysis and positioning.

[0062] In some embodiments, the method may further include:

[0063] If there is no completion message returned to the flash translation layer within the first preset time period, detecting whether the time of a first timer corresponding to the flash channel controller is reduced to 0;

[0064] When the time of the first timer is reduced to 0, determining the target register and the target storage area in the double rate synchronous dynamic random access memory according to the current read and write operation request;

[0065] Trigger the target register to interrupt the current operation;

[0066] Importing the fault information in the target register into the target storage area in the double data rate synchronous dynamic random access memory, so that when the flash translation layer determines that the time of the second timer corresponding to the flash translation layer is reduced to 0, checking whether there is new data in the storage area corresponding to each channel in the double data rate synchronous dynamic random access memory, if there is new data in the storage area, determining the target channel corresponding to the storage area with the new data, and returning a write request for other normal channels in the flash channel controller except the target channel;

[0067] Get the write request returned by the flash translation layer;

[0068] According to a write request, the fault information in the target storage area of ​​the double rate synchronous dynamic random access memory is written into the non-volatile memory through other normal channels except the target channel.

[0069] It should be noted that, in the embodiment of the present invention, a corresponding first timer can be pre-set for the flash channel controller, and the first timer is reset to the second preset duration each time a context switch occurs, and the countdown starts after the reset. If the flash channel controller has not returned a completion message to the flash conversion layer within the first preset duration, it can be determined that the flash channel controller has a context stuck situation, and at this time, it can be detected whether the countdown of the first timer corresponding to the flash channel controller has become 0, and if the countdown of the first timer has become 0, the target register and the target storage area of ​​the double rate synchronous dynamic random access memory can be determined according to the current read and write operation. In practical applications, a mapping relationship between the channel and the register can be established in advance, and a mapping relationship between the channel and the storage area in the DDR can be established. After locating the fault channel according to the current read and write operation request, the target register corresponding to the fault channel can be further determined according to the fault channel combined with the mapping relationship between the channel and the register, and the target storage area corresponding to the fault channel can be determined according to the fault channel combined with the mapping relationship between the channel and the DDR storage area.

[0070] After the target register is determined, the target register is immediately triggered to interrupt the current operation, and the fault information in the target register (ie, the value of the context-related key variable) is imported into the target storage area in the double rate synchronous dynamic random access memory.

[0071] A second timer is set in advance for the upper flash conversion layer, and the second timer starts counting down from a third preset time length. When it is detected that the time of the second timer is reduced to 0, the flash conversion layer actively checks whether there is new content in the storage area corresponding to each channel in the DDR. If new content is found in a certain storage area, it means that the flash channel controller of the back-end has imported the fault information in the corresponding register into the storage area. At this time, the storage area storing the new data can be determined, and the corresponding target channel (that is, the faulty channel) can be determined according to the pre-established mapping relationship between the channel and the storage area. Then, a write request for other normal channels except the target channel is generated, and the write request is sent to the flash channel controller of the back-end. After receiving the write request, the flash access register flushes the fault information in the target register to the non-volatile memory through other normal channels except the target channel according to the write request.

[0072] In one embodiment, the method may further include:

[0073] After returning the write request for other normal channels except the target channel in the flash channel controller, the second timer is reset to a third preset duration and starts counting down.

[0074] It should be noted that in order to further ensure that the upper-layer flash memory conversion layer can promptly discover the fault information that has been imported into a storage area in the double-rate synchronous dynamic random access memory, and promptly notify the flash memory channel controller to write the fault information in the storage area into the non-volatile memory through other normal channels, in an embodiment of the present invention, after the flash memory conversion layer sends the generated write request for other normal channels except the faulty channel to the flash memory channel controller, the second timer corresponding to the flash memory conversion layer can be immediately reset to the third preset duration, and the countdown of the second timer can be started.

[0075] In some embodiments, the method may further include:

[0076] After the fault information in the target storage area of ​​the double rate synchronous dynamic random access memory is written into the nonvolatile memory, the fault information in the target storage area of ​​the double rate synchronous dynamic random access memory is cleared.

[0077] Please refer to Figure 2 A flowchart of another method for processing fault information of a solid-state drive is shown. In practical applications, in order to further ensure data security and reduce the possibility of loss, the non-volatile memory in the embodiment of the present invention can adopt SLC (Single-Level Cell, single-layer unit flash memory) NAND (non-volatile memory).

[0078] It should be noted that in order to save storage space in the embodiment of the present invention, the fault information stored in the target storage area in the double-rate synchronous dynamic random access memory DDR can be written into the non-volatile memory through other normal channels except the fault channel, and after the writing is completed, the fault information stored in the target storage area can be cleared, thereby reducing the storage space occupied, which is beneficial to improving the performance of the solid-state hard drive.

[0079] It can be seen that in the embodiment of the present invention, when the flash channel controller identifies that the fault type is a preset fault type, if a completion message can be returned to the flash conversion layer within the first preset time period to indicate that the context is not stuck, the fault field information can be added to the completion message, and the corresponding register is triggered to interrupt the current operation, and the key variable value related to the context in the register (that is, the fault information) is imported into the target storage area corresponding to the fault channel in the double-speed synchronous dynamic random access memory, and the completion message is returned to the flash conversion layer. The flash conversion layer sends a write request for other normal channels except the fault channel to the flash channel controller according to the completion message. The flash channel controller can flush the fault data imported into the target storage area in the double-speed synchronous dynamic random access memory to the non-volatile memory through other normal channels according to the write request. Since the data in the non-volatile memory will not be lost due to power failure, storing the fault data through the non-volatile memory can better prevent data loss and ensure data security. When locating the fault, the fault data can be directly obtained from the non-volatile memory, which is conducive to improving the efficiency of fault locating.

[0080] In addition, the embodiment of the present invention can also improve the fault tolerance of on-site customer operations during use, and even if the power is abnormally off, it will not delay the fault location progress of the back-end flash channel controller related errors. After the fault occurs, the fault information in the non-volatile memory can be automatically read after the power is turned off and then powered on, and the fault information can be located, which is also helpful to avoid extending the power-on time of the solid-state hard disk.

[0081] The present invention also provides a corresponding device for the fault information processing method of the solid state drive, which further makes the method more practical. Among them, the device can be described from the perspective of functional modules and hardware.
