Hierarchical system manager rollback
Granted: April 4, 2017
Patent Number:
9612920
Data state rollover is performed based on data state snapshots and deltas. A series of snapshots is taken of the current data state, an original data state, and data states in between. Deltas are then generated between two sequential snapshots. This results in numerous deltas which represent the difference between consecutive snapshots. Once the deltas are acquired, the deltas may be stored along with the snapshot of the present data state. As such, previous data states may be rolled…
Raid set initialization
Granted: April 4, 2017
Patent Number:
9612745
Embodiments of the presently claimed invention enable a RAID set to appear as if it were initialized immediately after a command to initialize a RAID set is initiated.
