Abstract: In accordance with embodiments disclosed herein, there is provided systems and methods for remapping of memory in memory control architectures. A processing device includes a processing core and a platform controller hub (PCH) coupled to the processing core. The PCH is to receive an indication of a failure associated with a first memory region of a plurality of memory regions residing in a memory. The PCH is also to interrupt an operating system to prompt for a reboot. Upon the reboot, the PCH is to remap a memory address range associated with the first memory region to a second memory region of the plurality of regions.

Abstract: An access point IHS group controller failover system includes a first access point IHS group controller that controls a first access point IHS group that includes plurality of access point IHSs. Following a failure of the first access point IHS group controller, the first access point IHS broadcasts a first access point IHS identifier to a first subset of the plurality of access point IHSs. The first access point IHS then registers the first subset of the plurality of access point IHSs as members of a second access point IHS group, and controls at least some functions of the second access point IHS group. When the first access point IHS detects activity from the first access point IHS group controller, it instructs the first subset of the plurality of access point IHSs in the second access point IHS group to reconnect to the first access point IHS group controller.

Abstract: Embodiments are directed to a method of online storage device firmware upgrades by suspending input/output (I/O) operations to the storage device upon notification of a firmware upgrade to the storage device, maintaining a stripe log that contains data stripes updated by I/O operations issued to the storage device during suspension of the storage device, triggering the firmware upgrade to the storage device while the storage device is in suspension, reactivating the disk and new firmware upon completion of the firmware upgrade, and reconstructing the updated data stripes from the stripe log on the storage device after the reactivating step.

Abstract: Data storage systems are provided that include network interfaces each configured to receive storage operations issued by one or more host systems for handling by the data storage system, and transfer the storage operations over a Peripheral Component Interconnect Express (PCIe) fabric. The data storage systems also include processors configured to receive the storage operations over the PCIe fabric, process properties of the storage operations against allocation information of a shared PCIe address space to determine target processors to handle the storage operations, and selectively transfer ones of the storage operations to the target processors for handling of the storage operations with associated storage drives coupled over the PCIe fabric. The data storage systems also identifie failed ones of the processors and responsively initiate backup ones of the processors to handle portions of the shared PCIe address space handled by the failed ones of the processors.

Abstract: A method, computer program product, and computer system for performing, via a first computing device, a copy sweep operation to a first range of data on a source storage device. It may be determined that the copy sweep operation has failed. A message may be sent to a second computing device to suspend I/O operations to the first range of data. The copy sweep operation may be retried based upon, at least in part, determining that the copy sweep operation has failed, wherein the copy sweep operation may be retried without the first computing device receiving acknowledgement that the second computing device is suspending the I/O operations to the first range of data.

Abstract: A control module that manages a segment to which data is written implements write processing and resynchronization processing using a bitmap managed for each LUN. In other words, the control module stores the bitmap for the managed LUN in a bitmap storage unit. A mirror LUN control unit sets a corresponding portion of the bitmap to 1, controls data write to a target segment and a mirror segment, and resets the bitmap to 0 when the data write to both of the segments is complete. A resynchronization control unit refers to the bitmap storage unit to perform the resynchronization processing.

Abstract: A power failure monitoring system and a method are disclosed herein, where the power failure monitoring system includes a motherboard, a board, a complex programmable logic device (CPLD) and a baseboard management controller (BMC) module. The motherboard includes a central processing unit (CPU) power and a non-CPU power. The board includes a board power. The BMC module includes a register that is electrically coupled to the CPLD. The CPLD is configured to execute a shutdown process when power failure occurs, identify a power failure type, and determine whether to execute a restart process according to the power failure type. If the restart process is executed and a count of the restart process reaches a predetermined count, the CPLD records lock information in the register. The BMC module is configured to record the count of the restart process, and execute a lock process according to the lock information.
