Patent number: 10951051Abstract: An information handling system includes a power supply unit (PSU) and a power assist unit (PAU). The PSU provides a power rail to power a load, and a constant current indication that indicates whether the power supply unit is operating in a constant current mode. The PAU is coupled to the power rail, and includes a power storage element, a converter coupled to the power storage element and to the power rail, and a controller. The controller receives an enable signal when the constant current indication indicates that the first power supply unit is operating in the constant current mode, and in response, the controller directs the converter to convert a voltage from the power storage element and to a current to the power rail to meet an additional demand of the load for power. When the controller does not receive the enable signal, the controller directs the converter to charge the power storage element from the power rail.Type: GrantFiled: October 30, 2018Date of Patent: March 16, 2021Assignee: Dell Products, L.P.Inventors: John E.

Patent number: 10599503Abstract: An information handling system may implement techniques for triggering power loss protection on solid-state storage devices (SSDs) based on PSU pre-warning signals (such as de-asserted POK or VIN_GOOD signals) indicating that power loss is imminent. The pre-warning signals may be provided directly to SSDs over a dedicated connection or may be passed through other components of the information handling system (such as power loss warning logic, a platform controller hub, or a CPU) to a storage controller. The pre-warning signal may be provided to the storage controller as a power loss warning interrupt. This interrupt may cause the storage system controller to issue an in-band message/command to the SSDs or to provide a signal on a dedicated connection to the SSDs in order to trigger power loss protection actions on the SSDs, including switching their power sources and flushing write queues before available hold-up energy is depleted.Type: GrantFiled: July 28, 2016Date of Patent: March 24, 2020Assignee: Dell Products L.P.Inventors: Amir Rahmanian, John E.

Patent number: 10474583Abstract: An information handling system may implement a method for controlling cache flush size by limiting the amount of modified cached data in a data cache at any given time. The method may include keeping a count of the number of modified cache lines (or modified cache lines targeted to persistent memory) in the cache, determining that a threshold value for modified cache lines is exceeded and, in response, flushing some or all modified cache lines to persistent memory. The threshold value may represent a maximum number or percentage of modified cache lines. The cache controller may include a field for each cache line indicating whether it targets persistent memory. Limiting the amount of modified cached data at any given time may reduce the number of cache lines to be flushed in response to a power loss event to a number that can be flushed using the available hold-up energy.Type: GrantFiled: July 28, 2016Date of Patent: November 12, 2019Assignee: Dell Products L.P.Inventors: John E. Jenne, Stuart Allen Berke, Vadhiraj Sankaranarayanan

Patent number: 10459733Abstract: A halt event separates a boot up operation from a run time operation. A controller grants a request from a baseboard management controller for an electrical power associated with a boot-up operation. As the baseboard management controller completes the boot-up operation (such as a power on self-test), the baseboard management controller predicts the electrical power that is required for a run time operation (e.g., executing an operating system). The baseboard management controller is then required or forced to submit a subsequent request for the additional electrical power that is required for the run time operation. The controller compares the electrical power predicted for the run time operation to a power availability from a power supply (such as a safe or maximum operating condition). If the power supply can provide the electrical power predicted to be required during the run time operation, then the controller may permit or authorize a transition from the boot up operation to the run time operation.Type: GrantFiled: January 25, 2018Date of Patent: October 29, 2019Assignee: Dell Products, LPInventors: John E. Jenne, Kyle E. Cross

Patent number: 10394710Abstract: An SCM memory mode NVDIMM-N cache system includes an SCM subsystem, and an NVDIMM-N subsystem having at volatile memory device(s) and non-volatile memory device(s). A memory controller writes data to the volatile memory device(s) and, in response, updates a cache tracking database. The memory controller then writes a subset of the data to the SCM subsystem subsequent to the writing of that data to the volatile memory device(s) and, in response, updates the cache tracking database. The memory controller then receives a shutdown signal and, in response, copies the cache tracking database to the volatile memory device(s) in the NVDIMM-N subsystem. The NVDIMM-N subsystem then copies at least some of the data and the cache tracking database from the volatile memory device(s) to the non-volatile memory device(s) prior to shutdown. The data and the cache tracking database may then be retrieved from non-volatile memory device(s) when the system is restored.Type: GrantFiled: October 17, 2017Date of Patent: August 27, 2019Assignee: Dell Products L.P.Inventors: Stuart Allen Berke, John E.
