摘要：Techniques described herein relate to systems and methods of data storage,and more particularly to providing layering of file system functionality on an objectinterface. In certain embodiments, file system functionality may be layered on cloud
object interfaces to provide cloud-based storage while allowing for functionality
expected from a legacy applications. For instance, POSIX interfaces and semantics may belayered on cloud-based storage, while providing access to data in a manner consistentwith file-based access with data organization in name hierarchies. Various embodimentsalso may provide for memory mapping of data so that memory map changes are
reflected in persistent storage while ensuring consistency between memory map changesand writes. For example, by transforming a ZFS file system disk-based storage into ZFScloud-based storage, the ZFS file system gains the elastic nature of cloud storage.
