Abstract: In addition to caching I/O operations at a host, at least some data management can migrate to the host. With host side caching, data sharing or deduplication can be implemented with the cached writes before those writes are supplied to front end storage elements. When a host cache flush to distributed storage trigger is detected, the host deduplicates the cached writes. The host aggregates data based on the deduplication into a “change set file” (i.e., a file that includes the aggregation of unique data from the cached writes). The host supplies the change set file to the distributed storage system. The host then sends commands to the distributed storage system. Each of the commands identifies a part of the change set file to be used for a target of the cached writes.

Abstract translation: 除了在主机上缓存I / O操作之外，至少有一些数据管理可以迁移到主机。 使用主机缓存，可以在缓存的写入之前，将这些写入提供给前端存储元件，实现数据共享或重复数据消除。 当检测到主机缓存冲突到分布式存储触发器时，主机将重复数据删除缓存的写入。 主机将基于重复数据删除的数据聚合到“更改集文件”（即包含来自缓存的写入的唯一数据的聚合的文件）中。 主机将更改集文件提供给分布式存储系统。 然后主机向分布式存储系统发送命令。 每个命令都标识要用于缓存写入目标的更改集文件的一部分。

Abstract: A storage management computing device, method and non-transitory computer readable medium that persist data on non-volatile memory includes maintaining a data storage structure comprising multiple nodes on non-volatile memory in at least one storage server. A determination is made when a received key in an update matches an existing key in one of the multiple nodes in the data storage structure. When the determination indicates the match, the update is provided for insertion in a slot in a vector extending from the existing key in the one of the multiple nodes for the data storage structure which matches the received key.
