  • Enabling or disabling data reduction based on measure of data overwrites
    Patent number: 11989415
    Abstract: In some examples, a system computes a measure of data overwrites to a data segment stored in a storage structure, where the measure of data overwrites indicates a quantity of overwrites of data in the data segment. The system compares the measure of data overwrites to a criterion. In response to determining that the measure of data overwrites has a first relationship with respect to the criterion, the system disables data reduction for the data segment.
    Type: Grant

  • Converting a virtual volume between volume types
    Patent number: 11321002
    Abstract: In some examples, a system converts a virtual volume from a first volume type to a second volume type without modifying the virtual volume, the converting comprising accessing a source metadata associated with the virtual volume, the source metadata including information for the first volume type, and generating a destination metadata associated with the virtual volume, the destination metadata including information for the second volume type. While the virtual volume is being converted from the first volume type to the second volume type, the system processes a write operation that accesses a portion of the virtual volume and changes data in the accessed portion of the virtual volume.
