  • Storage tier management for file systems
    Patent number: 11461241
    Abstract: Embodiments are directed to managing data in a file system. A file system that includes a file storage tier and a cache storage tier may be provided. An amount of hot blocks present in the cache storage tier that are associated with a heat score that matches a maximum heat score value may be determined. In response to the amount of hot blocks exceeding an amount threshold value further actions may be performed, including: determining each cooldown block in the cache storage tier based on each heat score associated with each block in the cache storage tier; and decrementing the heat score associated with each cooldown block. In response to one or more blocks in the cache storage tier being read, the heat score associated with the one or more blocks being read may be set to the maximum heat score value.
