Abstract
Systems and methods for reducing read application in a virtual storage system are provided. According to one embodiment, heuristic data may be tracked and utilized in real-time by a file system of the virtual storage system at the level of granularity of a volume, thereby allowing a fast path flag to be enabled/disabled at a volume level during various phases of operation of a workload. The heuristic data for a given volume may be indicative of a correlation between (i) data blocks stored on the given volume being located within a compressible zone of a zoned checksum scheme and (ii) the respective data blocks containing compressed data and a corresponding checksum. Based on the heuristic data, read requests may be selectively directed to the read path (e.g., a fast path or a slow path) expected to mitigate read amplification when data compression is enabled for a zoned checksum scheme.
