    • Embodiments of the present invention provide a method for writing data into a flash memory apparatus, a flash memory apparatus, and a storage system. In the embodiments of the present invention, when an effective capacity of a first block among multiple blocks is less than a size of first target data, a primary controller divides the first target data into first part and second part, where a size of the first part is the effective capacity of the first block, and a size of the second part is the size of the first target data minus the size of the first part; determines a second block from the multiple blocks, where the second block is a block that has been written with data but is not filled with data; and writes the first part into the first block and writes the second part into the second block, which can improve block utilization and save storage space of an SSD.
    • 本发明的实施例提供了一种用于将数据写入闪存装置,闪存装置和存储系统的方法。 在本发明的实施例中,当多个块中的第一块的有效容量小于第一目标数据的大小时,主控制器将第一目标数据划分为第一部分和第二部分,其中第一部分和第二部分的大小 部分为第一块的有效容量,第二部分的大小为第一目标数据的大小减去第一部分的大小; 从多个块中确定第二块,其中第二块是已经用数据写入但未填充数据的块; 并将第一部分写入第一部分,并将第二部分写入第二部分,这可以提高块利用率并节省SSD的存储空间。

    • Embodiments of the present invention disclose a method and apparatus of cache management for a non-volatile storage device, and relate to the field of data processing technologies, which avoid frequent replacement of dirty pages, increase a service life of the storage device, reduce the implementation cost, and improve the execution efficiency. The embodiments of the present invention includes: determining a size relationship between a capacity sum of a clean page subpool and a dirty page subpool and a cache capacity; determining, when the capacity sum of the clean page subpool and the dirty page subpool is greater than or equal to the cache capacity, whether identification information of a to-be-accessed page is in a history list of clean pages or a history list of dirty pages; and when it is determined that the identification information of the to-be-accessed page is in the history list of clean pages, adding a first adjustment value to a clean subpool capacity threshold; or when the identification information of the to-be-accessed page is in the history list of dirty pages, subtracting a second adjustment value from the clean subpool capacity threshold. The embodiments of the present invention are mainly applied to cache management processes for non-volatile storage devices.
    • 本发明的实施例公开了一种用于非易失性存储设备的高速缓存管理的方法和装置,并且涉及数据处理技术领域,其避免频繁更换脏页,增加存储设备的使用寿命,减少 实施成本,提高执行效率。 本发明的实施例包括:确定清洁页面子站和脏页面子站的容量和与高速缓存容量之间的大小关系; 当清洁页面子站和脏页面子站的容量总和大于或等于高速缓存容量时,确定要访问页面的标识信息是否在干净页面的历史列表或历史列表中 脏页; 并且当确定要访问页面的识别信息在清洁页面的历史列表中时,将第一调整值添加到干净的子库容量阈值; 或者当待访问页面的识别信息在脏页的历史列表中时,从干净的子池容量阈值减去第二调整值。 本发明的实施例主要应用于非易失性存储设备的高速缓存管理过程。
