  • Patent number: 10132870
    Abstract: A system for dynamic discharging to detected derated battery cells. In such a system, a battery cell capacity, cell voltage, as well as a time to discharge are used in combination to identify good or bad battery cells. More specifically, during a dynamic discharge cycle, an accumulated discharge capacity value is calculated and monitored by a charge level battery gas gauge via analog to digital (A/D) converters and an internal discharge time value is monitored. One of the values is assigned as a fixed value and the other value is used to identify good or bad batter cells.

  • Patent number: 9632935
    Abstract: In some embodiments, a method for controlling a cache having a volatile memory and a non-volatile memory during a power up sequence is provided. The method includes receiving, at a controller configured to control the cache and a storage device associated with the cache, a signal indicating whether the non-volatile memory includes dirty data copied from the volatile memory to the non-volatile memory during a power down sequence, the dirty data including data that has not been stored in the storage device. In response to the received signal, the dirty data is restored from the non-volatile memory to the volatile memory, and flushed from the volatile memory to the storage device.

  • Patent number: 8370659
    Abstract: Systems and methods that may be implemented for time-based management of storage memory controller (e.g., RAID controller) backup battery life in information handling systems by limiting the backup battery system operation time in order to save energy, reduce the impact of leakage current, and prolong memory controller backup battery shelf life while at the same time meeting requirements of back-up time for storage/server applications. The disclosed systems and methods may be implemented, for example, by providing a battery system controller that implements a pre-set memory controller backup battery operation time, in combination with a hardware-controlled mechanism that extends backup battery system operation time by disabling one or more current leakage paths within the storage memory controller circuitry.

  • Patent number: 8151011
    Abstract: Determining whether there exists an input-output (I/O) fabric conflict (mismatch) between a blade I/O fabric daughter card of a blade compute module and an I/O interface module of a blade compute module system, and if a conflicts does exit then taking action to correct this I/O fabric mismatch. An I/O fabric router may be coupled between the blade I/O fabric daughter cards and the system I/O interface modules. If a matching I/O interface fabric exists then the I/O fabric router will couple the blade I/O fabric daughter card to the matching I/O interface fabric. If there is no matching I/O interface fabric then the blade I/O fabric daughter card may be decoupled from the blade compute module system so that the associated blade compute module may otherwise function, and an alert may be sent regarding the I/O fabric conflict (absence of an I/O fabric match) for the I/O fabric daughter card of the blade compute module.

  • Patent number: 8129947
    Abstract: Methods and systems are disclosed for utilizing a memory control circuit for controlling transfer of data to and from a memory system. A memory control circuit with a back up battery and control circuits is provided. Battery health is determined through a discharge cycle of the back up battery. A power supply generated from the back up battery is provided to circuitry of the memory control card during normal operations of the memory control circuit during a non-power loss state. The power supplied from the back up battery during the non-power loss state of the memory control circuit is utilized by at least a first circuit of the memory control circuit as part of normal memory controller card operations during the battery health discharge cycle. When the system is not performing a battery health cycle the first circuit receives normal system power. The memory control circuit may be a RAID card. The first circuit may be memory circuitry.

  • Patent number: 7880437
    Abstract: A quick conditioning cycle system to avoid performance degradation at the end of calibrating cycle. The quick conditioning cycle system discharges a battery to a level where battery remaining capacity is still high enough to backup memory at a guaranteed period of time. During the quick learning cycle, the battery pack is discharged from a full charge. If measured capacity exceeds a predetermined threshold (Cpc), calibration stops. Otherwise, the quick conditioning cycle system reports a defected battery when measured capacity is less than Cpc and continues discharging to a full conditioning cycle, if desired.

  • Patent number: 7721096
    Abstract: A blade server module in an information handling system may have secure environment and authorized removal modes in non-volatile memory. If the secure environment mode is set in the blade server module, then the authorized removal mode is read to determine whether it also is set. If both of these modes are set then authentication keys of the inserted blade server module and blade server chassis are verified as being properly associated. If the authorized removal mode is not set when the blade server module is inserted into a server chassis or authentication keys are not verified as being properly associated then the blade server module power-up sequence is disabled. The authentication keys may be administrator/user defined. The secure environment and authorized removal modes may be set and cleared by the administrator/user.

  • Patent number: 7672141
    Abstract: A component and card coupling alignment and support apparatus includes a card. A primary component connector is mounted to the card. A primary component including a connection edge engages the primary component connector. A secondary component extends from the primary component. An alignment and support member is included on the secondary component, whereby the card engages the alignment and support member on the secondary component. The engagement of the alignment and support member with the card aligns the primary component with the primary component connector during their coupling and supports the primary component in the primary component connector after their coupling. The card may then be coupled to an information handling system connector in an information handling system.
