  • Optimizing dynamic power loss protection adjustment in a storage system
    Patent number: 12001684
    Abstract: A first amount of energy to be stored at one or more power loss protection (PLP) components is determined to enable storage of data at a plurality of storage devices of a storage system upon an occurrence of a power failure. A first voltage is provided to the one or more PLP components that corresponds to the first amount of energy. A second amount of energy to be stored at the one or more PLP components is determined based on a change in the storage system. A second voltage is provided to the one or more PLP components that corresponds to the second amount of energy.

  • Upgrade for system with differing capacities
    Patent number: 11836348
    Abstract: In one implementation, a system resource is added to a storage system, for a resource-preserving upgrade. An upgrade component is coupled to the storage system as a temporary storage system shelf. Storage drives are moved from the storage system to the upgrade component. One or more storage controllers of the upgrade component are promoted to take over data services from the storage system.

  • Asynchronous arbitration of shared resources
    Patent number: 11144358
    Abstract: An exemplary system includes first and second controllers each configured to selectively operate in a master state and a standby state, a first watchdog timer associated with the first controller, and a second watchdog timer associated with the second controller. Each watchdog timer is configured to be either unexpired or expired. Selectively, the first controller operates in the master state and the second controller operates in the standby state when the first watchdog timer is unexpired and the second watchdog timer is expired, the first controller operates in the standby state and the second controller operates in the master state when the first watchdog timer is expired and the second watchdog timer is unexpired, and the first and second controllers both operate in the standby state when both the first and the second watchdog timer are expired or when both the first and the second watchdog timer are unexpired.
