| الوصف: | File systems are tasked with storing, organizing, and retrieving valuable data for long periods of time. This requires them to provide excellent fault-tolerance and reliability standards throughout their extended lifetime. As a result, most file systems follow a conservative development model and evolve slowly. In comparison, the underlying storage hardware, as well as the requirements of the modern storage environment are changing much more rapidly. Due to the growing adoption of Storage Virtualization, hardware configurations have grown in complexity, but the file system is shielded from the details by the block interface. This puts file systems at a disadvantage when trying to make efficient use of the underlying hardware and in general, acts as an impediment to meeting higher-level goals for the storage stack entirely from within the file system. At the same time, the block interface also obfuscates most of the vital file system context from the hardware, limiting its ability to compensate for the file system’s limitations and make sound decisions for the entire storage system. We show that simple hints from the file system exposed to a cognisant block layer can be effective in achieving high-level goals for the storage system without requiring functional modifications to existing components of the storage stack, like the file system itself or the block interface.
