  • Method and system for dynamic upgrade predictions for a multi-component product
    Patent number: 11474803
    Abstract: Techniques are disclosed for generating a dynamic upgrade prediction. The prediction includes generating an initial upgrade prediction for an upgrade to be performed on a subset of component nodes; performing a real time progress review, using a centralized management node, of the upgrade, wherein each of the component nodes includes a number of stages; performing an upgrade duration comparison between the initial upgrade prediction and a real time upgrade time for a subset of the stages; and generating an updated upgrade prediction for the multi-component product upgrade based on the comparison between the initial upgrade prediction and the real time upgrade time.

  • Retention time based consistent hash ring
    Patent number: 11372728
    Abstract: A retention-based consistent hash ring process defines each file name in the system to include its expiration date (or time) as a prefix or suffix that is stored and indexed as metadata. The process uses a virtual node to represent adjacent expiration days to create virtual nodes based on individual days of the week. Each physical node contains the same number of labeled virtual nodes, and the consistent hash ring process is used to move files with the same expiration day to different physical nodes by looking for next labeled virtual nodes on the hash ring. This provides a way to locate the virtual node storage location by specifying a file's expiration date as part of the key used in the hash ring process, and distributes files that may otherwise be assigned to the same physical node through a backup policy.
