Abstract: Among other things, one or more techniques and/or systems are provided for storing data within a hybrid storage aggregate comprising a lower-latency storage tier and a higher-latency storage tier. In particular, frequently accessed data, randomly accessed data, and/or short lived data may be stored (e.g., read caching and/or write caching) within the lower-latency storage tier. Infrequently accessed data and/or sequentially accessed data may be stored within the higher-latency storage tier. Because the hybrid storage aggregate may comprise a single logical container derived from the higher-latency storage tier and the lower-latency storage tier, additional storage and/or file system functionality may be implemented across the storage tiers. For example, deduplication functionality, caching functionality, backup/restore functionality, and/or other functionality may be provided through a single file system (or other type of arrangement) and/or a cache map implemented within the hybrid storage aggregate.

Abstract translation: 除其他之外，提供一个或多个技术和/或系统用于在包括较低延迟存储层和较高延迟存储层的混合存储聚合中存储数据。 特别地，经常访问的数据，随机访问的数据和/或短寿命数据可以在较低延迟存储层内被存储（例如，读取高速缓存和/或写入高速缓存）。 不经常访问的数据和/或顺序访问的数据可以存储在更高延迟的存储层中。 因为混合存储聚合可以包括从较高延迟存储层和较低延迟存储层导出的单个逻辑容器，所以可以跨存储层实现附加的存储和/或文件系统功能。 例如，重复数据删除功能，缓存功能，备份/恢复功能和/或其他功能可以通过单个文件系统（或其他类型的安排）和/或在混合存储聚合中实现的缓存映射来提供。
