摘要： A method for adaptive concurrency for write persistence in a storage system, performed by the storage system, is provided. The method includes selecting a write process from among a plurality of write processes, responsive to receiving a write request for writing data into the storage system, and writing the data into the storage system in accordance with the selected write process. One of the plurality of write processes includes transferring the data into the storage system, locking an inode associated with file information of the data in memory, updating the file information in the inode while the inode is locked, committing the data while the inode is locked, and unlocking the inode.
摘要翻译：提供了由存储系统执行的用于存储系统中的写入持久性的自适应并发性的方法。该方法包括响应于接收到用于将数据写入存储系统的写入请求而从多个写入过程中选择写入过程，并且根据所选择的写入过程将数据写入存储系统。多个写入过程中的一个包括将数据传送到存储系统，将与数据的文件信息相关联的inode锁定在存储器中，在inode被锁定时更新inode中的文件信息，在inode被锁定的同时提交数据，并解锁inode。

摘要： The method generates a first deduplication map (DDM) level of a DDM pyramid. The DDM pyramid identifies locations of data stored in the persistent storage resource of the deduplication system. The method further determines a first false positive rate target for a first index summary (IS) level of an index pyramid based on a memory footprint for the first IS level and an aggregate false positive rate target for the index pyramid. The first IS level accelerates lookup into the first DDM level. The first false positive rate target indicates a rate that a hit for a value found in the first IS level i s not found in the first DDM level. The method also generates the first IS level with a first false positive rate based on the determined first false positive rate target.
摘要翻译：该方法生成DDM金字塔的第一去重复映射（DDM）级别。 DDM金字塔标识存储在重复数据删除系统的永久存储资源中的数据的位置。该方法进一步基于第一IS级别的存储器覆盖区和索引金字塔的聚集误报率目标来确定用于索引金字塔的第一索引摘要（IS）级别的第一误报率目标。第一个IS级别加速查找第一个DDM级别。第一误报率目标指示在第一DDM级别中找不到在第一IS级别中找到的值的命中的比率。该方法还基于所确定的第一假阳性率目标产生具有第一假阳性率的第一IS水平。
