背景技术Background technique
目前，固态硬盘（Solid State Disk，SSD）设计中将硬盘划分为众多独立的物理单元，用于存储数据。硬盘数据的读写异常分为两种情况，一些是硬盘的物理性损坏造成的，一些是硬盘的逻辑性损坏造成的。一般来说，如果是物理性损坏造成的硬盘损伤，只能报废整个硬盘，这对用户来说是不小的损失，尤其是大容量硬盘。而如果不更换硬盘，继续对发生物理性损坏的硬盘中的数据进行读写操作，会严重影响固态硬盘的性能和稳定性。Currently, the design of Solid State Disk (SSD) divides the hard disk into many independent physical units for storing data. There are two types of abnormal reading and writing of hard disk data. Some are caused by physical damage to the hard disk, and some are caused by logical damage to the hard disk. Generally speaking, if the hard drive is damaged due to physical damage, the entire hard drive can only be scrapped, which is a considerable loss to the user, especially for large-capacity hard drives. If you do not replace the hard drive and continue to read and write data in the physically damaged hard drive, the performance and stability of the solid-state drive will be seriously affected.

在监测到硬盘的某个物理单元发生损坏时，进一步监测硬盘的该物理单元是发生物理性损坏还是逻辑性损坏。如果硬盘发出异常的噪音，硬盘无法启动或没有任何反应等，则表明硬盘发生了物理性损坏。如果硬盘能够启动和正常旋转，但无法读取或写入数据，则可能是由于文件系统损坏、分区表错误或文件系统错误等逻辑问题引起的。When it is detected that a certain physical unit of the hard disk is damaged, it is further monitored whether the physical unit of the hard disk is physically damaged or logically damaged. If the hard drive makes abnormal noises, cannot start or has no response, etc., it indicates that the hard drive is physically damaged.

发生逻辑性损坏的硬盘可以在一定程度上进行恢复，与逻辑性损坏相比，物理性损坏较为复杂，因而本申请实施例对于发生物理性损坏的物理单元，可以采用区域隔离技术进行区域隔离处理，以防止数据读取或写入，导致物理单元的进一步的损坏。A hard disk that is logically damaged can be restored to a certain extent. Compared with logical damage, physical damage is more complicated. Therefore, in the embodiment of this application, regional isolation technology can be used to perform regional isolation processing for physical units that are physically damaged. , to prevent data reading or writing from causing further damage to the physical unit.
S13，获取所述物理单元的访问热度。S13: Obtain the access popularity of the physical unit.
当所述物理单元没有发生物理性损坏时，为了保护物理单元中的重要数据，可以定期获取所述物理单元的访问热度，从而根据访问热度确定物理单元中的数据是否为重要数据，进而判断是否需要进行备份。When the physical unit is not physically damaged, in order to protect the important data in the physical unit, the access heat of the physical unit can be obtained regularly, so as to determine whether the data in the physical unit is important data based on the access heat, and then determine whether A backup is required.
可以通过记录物理单元的访问次数或者访问频率，得到物理单元的访问热度。访问次数越多或访问频率越高，访问热度越高，访问次数越少或访问频率越少，访问热度越低。The access popularity of a physical unit can be obtained by recording the number of accesses or access frequency of the physical unit. The more visits or the higher the frequency of visits, the higher the popularity of the visits. The fewer the number of visits or the less frequent the visits, the lower the popularity of the visits.
S14，判断所述访问热度是否大于预设访问热度阈值。S14: Determine whether the access popularity is greater than a preset access popularity threshold.
预设访问热度阈值为预先设置的用以判断物理单元中的数据是否为重要数据的临界值。The preset access heat threshold is a preset critical value used to determine whether the data in the physical unit is important data.
当所述访问热度大于或等于预设访问热度阈值时，表明物理单元中的数据为重要数据，执行S15；当所述访问热度小于预设访问热度阈值时，表明物理单元中的数据不为重要数据，执行S18。When the access heat is greater than or equal to the preset access heat threshold, it indicates that the data in the physical unit is important data, and S15 is executed; when the access heat is less than the preset access heat threshold, it indicates that the data in the physical unit is not important. data, execute S18.

不同型号的物理单元可能具有不同的可靠性和故障模式，所以需要确定硬盘中各物理单元的型号（即，硬盘的型号）来标识和区分不同的物理单元，与所述型号相似的物理单元的故障数据更适合预测所述物理单元发生何种类型的损坏及损坏的概率。Different models of physical units may have different reliability and failure modes, so it is necessary to determine the model of each physical unit in the hard disk (i.e., the model of the hard disk) to identify and distinguish different physical units. Physical units similar to the model are Failure data is more suitable for predicting what type of damage will occur to the physical unit and the probability of damage.

Historical fault data is historical fault data. Historical fault data can include model, fault type, fault occurrence time, fault duration, fault location, etc. Obtain the target historical fault data whose fault type is physical damage. By analyzing the target historical fault data, the probability of physical damage at each time point can be obtained. The probability of physical damage at each time point can be calculated according to the corresponding time point. The ratio of the number of physically damaged hard drives to the total number is obtained. The probability of physical damage occurring at each time point is subjected to histogram processing to obtain a time distribution diagram of physical damage failure probability. The distribution diagram reflects the probability of physical damage occurring to a physical unit at different time points. Use trends and patterns in historical failure data to build a time series model and use the time series model to predict the probability of physical damage to a physical unit within a specified time period.
通过分析相同或相似型号的目标物理单元的历史故障数据和应用时间序列模型，能够预测指定时间段内物理单元发生物理性损坏的概率，接着判断预测的概率是否超过预设概率阈值，当预测所述物理单元发生物理性损坏的概率超过预设概率阈值时，执行S16；当预测所述物理单元发生物理性损坏的概率未超过预设概率阈值时，执行S18。By analyzing the historical failure data of the target physical unit of the same or similar model and applying the time series model, the probability of physical damage to the physical unit within a specified time period can be predicted, and then it is judged whether the predicted probability exceeds the preset probability threshold. When the predicted probability When the probability of physical damage to the physical unit exceeds the preset probability threshold, execute S16; when the predicted probability of physical damage to the physical unit does not exceed the preset probability threshold, execute S18.
S16，在所述硬盘中为所述物理单元分配备用单元，并将所述物理单元中的数据备份至所述备用单元。S16: Allocate a spare unit to the physical unit in the hard disk, and back up the data in the physical unit to the spare unit.
硬盘由控制单元、默认预留区和物理单元组成，物理单元负责存储数据，默认预留区用于为存储区的坏块提供替换的预留块，控制单元负责控制数据的读取与写入。The hard disk consists of a control unit, a default reserved area and a physical unit. The physical unit is responsible for storing data. The default reserved area is used to provide replacement reserved blocks for bad blocks in the storage area. The control unit is responsible for controlling the reading and writing of data. .
当物理单元发生物理性损坏，可以使用预留块选择算法，在默认预留区中，为物理性损坏的物理单元分配一个预留块作为备用单元。在为物理性损坏的物理单元分配备用单元后，可以将物理性损坏的物理单元中的数据复制到所述备用单元中，实现物理性损坏物理单元的数据的备份。When a physical unit is physically damaged, a reserved block selection algorithm can be used to allocate a reserved block as a spare unit to the physically damaged physical unit in the default reserved area. After allocating a spare unit to the physically damaged physical unit, the data in the physically damaged physical unit can be copied to the spare unit to realize the backup of the data in the physically damaged physical unit.
当物理单元没有发生物理性损坏，但物理单元的访问热度大于或等于预设访问热度阈值，且预测物理单元发生物理性损坏的概率超过预设概率阈值时，在默认预留区中，为访问热度较大且预测发生物理性损坏的概率较大的物理单元分配一个预留块作为备用单元。为便于描述，将访问热度较大且预测发生物理性损坏的概率较大的物理单元称之为大概率物理性损坏的物理单元。在为大概率物理性损坏的物理单元分配备用单元后，可以将大概率物理性损坏的物理单元中的数据复制到所述备用单元中，实现重要数据的提前备份。When no physical damage occurs to the physical unit, but the access heat of the physical unit is greater than or equal to the preset access heat threshold, and the predicted probability of physical damage to the physical unit exceeds the preset probability threshold, in the default reserved area, access is Physical units that are hotter and more likely to be physically damaged are allocated a reserved block as a spare unit. For convenience of description, a physical unit with high access heat and a high probability of predicted physical damage is called a physical unit with a high probability of physical damage. After allocating a spare unit to a physical unit with a high probability of physical damage, the data in the physical unit with a high probability of physical damage can be copied to the spare unit to achieve advance backup of important data.
示例性的，当硬盘中的物理单元A发生了物理性损坏时，根据预留块选择算法选择预留块C作为物理单元A的备用物理单元，预留块C的状态为未使用且存储状态为空。将物理单元A中的数据a进行备份到所述备用单元中。For example, when physical unit A in the hard disk is physically damaged, reserved block C is selected as a spare physical unit of physical unit A according to the reserved block selection algorithm. The status of reserved block C is unused and stored. Is empty. Back up data a in physical unit A to the backup unit.

所述区域管理表中存储了物理单元的物理地址与逻辑地址之间的映射关系。监测到有物理性损坏的物理单元或者大概率物理性损坏的物理单元时，控制芯片将物理性损坏的物理单元或者大概率物理性损坏的物理单元所对应的物理地址在区域管理表中标记为无效或故障状态，并将对应的备用单元的物理地址更新到区域管理表中，即在区域管理表中，关联存储了物理性损坏的物理单元的物理地址、逻辑地址及备用单元的物理地址。The mapping relationship between the physical address and the logical address of the physical unit is stored in the area management table. When a physically damaged physical unit or a physical unit with a high probability of physical damage is detected, the control chip marks the physical address corresponding to the physically damaged physical unit or a physical unit with a high probability of physical damage in the area management table as Invalid or faulty status, and updates the physical address of the corresponding spare unit to the regional management table. That is, in the regional management table, the physical address, logical address and physical address of the spare unit of the physically damaged physical unit are associated and stored.
示例性的，当硬盘中的物理单元A发生物理性损坏时，将区域管理表中物理单元A的物理地址x标记为无效，并对应增加备用单元B的物理地址m，即将区域管理表中物理单元A的逻辑地址y与物理地址m进行关联存储。For example, when physical unit A in the hard disk is physically damaged, the physical address x of physical unit A in the area management table is marked as invalid, and the physical address m of spare unit B is correspondingly increased, that is, the physical address The logical address y of unit A is stored in association with the physical address m.
硬盘中设置一个控制芯片，所述区域管理表存储于所述控制芯片中，便于后续在控制芯片中访问区域管理表，避免在硬盘频繁的读取区域管理表，造成硬盘损坏。A control chip is provided in the hard disk, and the area management table is stored in the control chip, which facilitates subsequent access to the area management table in the control chip and avoids frequent reading of the area management table in the hard disk, causing damage to the hard disk.

当计算机设备接收到访问请求时，对访问请求进行解析，得到需要访问的目标逻辑地址，在控制芯片的区域管理表中查找目标逻辑地址对应的目标物理地址。当确定目标物理地址后，根据目标物理地址访问固态硬盘中的目标数据，将访问请求映射到目标数据上进行处理。When the computer device receives the access request, it parses the access request to obtain the target logical address that needs to be accessed, and searches the target physical address corresponding to the target logical address in the area management table of the control chip. After the target physical address is determined, the target data in the solid state drive is accessed according to the target physical address, and the access request is mapped to the target data for processing.
在一些实施方式中，计算机接收到访问请求时，可以根据目标逻辑地址在控制芯片的区域管理表中查找物理单元的物理地址，当查找到与目标逻辑地址对应的目标物理单元的物理地址时，识别目标物理单元的物理地址是否有效。当目标物理单元的物理地址有效时，则将访问请求映射到目标物理单元的物理地址中的数据。当目标物理单元的物理地址无效时，则将访问请求映射到目标物理单元对应的目标备用单元的物理地址中的数据。In some embodiments, when the computer receives an access request, it can search the physical address of the physical unit in the area management table of the control chip according to the target logical address. When the physical address of the target physical unit corresponding to the target logical address is found, Identifies whether the physical address of the target physical unit is valid. When the physical address of the target physical unit is valid, the access request is mapped to the data in the physical address of the target physical unit. When the physical address of the target physical unit is invalid, the access request is mapped to the data in the physical address of the target standby unit corresponding to the target physical unit.
示例性的，当目标逻辑地址为y时，在区域管理表中寻找逻辑地址y对应的有效的物理地址m，将访问请求映射到物理单元B上。For example, when the target logical address is y, the effective physical address m corresponding to the logical address y is found in the area management table, and the access request is mapped to the physical unit B.
使用区域管理表将逻辑地址与物理地址进行映射及将物理单元的物理地址与备用单元的物理地址进行映射，当需要对目标数据进行访问时，在区域管理表中查询目标逻辑地址映射的目标物理地址，实现对目标数据的访问。这种映射关系确保了逻辑地址的抽象性，隐藏了底层物理区域的变化，同时提供了高性能和数据冗余的优势。Use the area management table to map the logical address to the physical address and map the physical address of the physical unit to the physical address of the standby unit. When the target data needs to be accessed, query the target physical address of the target logical address mapping in the area management table. Address to achieve access to target data. This mapping relationship ensures the abstraction of logical addresses, hides changes in the underlying physical area, and provides the advantages of high performance and data redundancy.
所述访问请求可以为更新目标数据，也可以为读取目标数据。The access request may be for updating target data or reading target data.
当所述访问请求为更新所述目标数据时，可以对所述访问请求进行解析，得到所述访问请求中的更新数据，根据所述控制芯片的缓冲存储器的空间余量对所述更新数据进行切分，得到多个更新子数据，将所述多个更新子数据逐个缓存至所述控制芯片的缓冲存储器中，并在每次缓存一个更新子数据后获取所述缓冲存储器的剩余空间余量，当所述剩余空间余量达到第一预设阈值时，根据所述缓冲存储器中缓存的更新子数据对所述目标数据进行更新。When the access request is to update the target data, the access request can be parsed to obtain the update data in the access request, and the update data can be processed according to the space margin of the buffer memory of the control chip. Segment to obtain multiple update sub-data, cache the multiple update sub-data one by one into the buffer memory of the control chip, and obtain the remaining space margin of the buffer memory after each update sub-data is cached. , when the remaining space margin reaches the first preset threshold, the target data is updated according to the update sub-data cached in the buffer memory.
在每次缓存一个更新子数据后，控制芯片会计算缓冲存储器的剩余空间余量，所述剩余空间余量表示缓冲存储器中还可以存储多少数据。一旦缓冲存储器中的剩余空间余量达到第一预设阈值时，说明缓冲存储器已经积累了足够的更新子数据，可以执行更新操作，此时将缓冲存储器中的更新数据写入目标物理单元中，实现对目标数据的更新。After each time an updated sub-data is cached, the control chip will calculate the remaining space margin of the buffer memory. The remaining space margin represents how much data can be stored in the buffer memory.

Segment to obtain multiple update sub-data, cache the multiple update sub-data one by one into the buffer memory of the control chip, and obtain the remaining space margin of the buffer memory after each update sub-data is cached. , when the remaining space margin reaches the first preset threshold, the target data is updated according to the update sub-data cached in the buffer memory.
在每次缓存一个更新子数据后，控制芯片会计算缓冲存储器的剩余空间余量，所述剩余空间余量表示缓冲存储器中还可以存储多少数据。一旦缓冲存储器中的剩余空间余量达到第一预设阈值时，说明缓冲存储器已经积累了足够的更新子数据，可以执行更新操作，此时将缓冲存储器中的更新数据写入目标物理单元中，实现对目标数据的更新。After each time an updated sub-data is cached, the control chip will calculate the remaining space margin of the buffer memory. The remaining space margin represents how much data can be stored in the buffer memory. Once the remaining space in the buffer memory reaches the first preset threshold, it means that the buffer memory has accumulated enough update sub-data and the update operation can be performed. At this time, the update data in the buffer memory is written into the target physical unit. Implement updates to target data.

在一个可选的实施方式中，所述根据所述控制芯片的缓冲存储器的空间余量对所述更新数据进行切分，得到多个更新子数据包括：In an optional implementation, dividing the update data according to the space margin of the buffer memory of the control chip to obtain multiple update sub-data includes:
根据所述更新数据的优先级及所述缓冲存储器的空间余量，确定所述更新数据在所述缓冲存储器中的存储空间；Determine the storage space of the update data in the buffer memory according to the priority of the update data and the space margin of the buffer memory;

You can also specify the priority of updated data in the access request.
通过考虑优先级，可以确定哪些更新数据应该被优先存储。对于优先级高的更新数据，则在缓冲存储器中分配较多的存储空间，使得更新数据能够被快速的写入缓冲存储器中，进而被快速的更新至目标物理地址中，实现对优先级高的更新数据的优先保护。对于优先级低的更新数据，则在缓冲存储器中分配较少的存储空间，避免占用优先级高的更新数据的存储资源。By considering priorities, you can determine which updated data should be stored first.
