  • Storage controller cache integrity management
    Patent number: 11403218
    Abstract: A system includes first and second redundant controllers, and at least one logical volume accessible to the first and second redundant controllers. The system also includes metadata fields associated with the at least one logical volume. The metadata fields include a first age field configured to store a first age value associated with the first controller and a second age field configured to store a second age value associated with the second controller. The first age value and the second age value are employed to provide an indication of whether cache data for the at least one logical volume is valid. The system further includes a processor configured to update the first and second age values in the respective first and second age fields.
    Type: Grant

  • Initializing stripes in storage array
    Patent number: 11243698
    Abstract: Initialization stripes of a redundant array of inexpensive disks (RAID) may include determining whether the stripes have already been initialized based on redundant correction information. Further, un-initialized stripes may be initialized before intended if write requests are received for such un-initialized stripes. Still further, rebuilt stripes (e.g., portions thereof) may also be checked to determine whether such rebuilt stripes have been initialized based on error detection codes.
