A Peripheral Component Interconnect express (PCIe) Downstream Port Containment (DPC) System Management Interrupt (SMI) storm prevention system includes a Basic Input/Output System (BIOS) subsystem coupled to a first PCIe device. In response to an error being experienced in the first PCIe device and causing the first PCIe device to perform DPC operations, the BIOS subsystem receives a plurality of SMIs that are each configured to begin a System Management Mode (SMM). The BIOS subsystem tracks a number of the plurality of SMIs in a BIOS database and determines when the number of the plurality of SMIs has reached a DPC SMI storm threshold. In response to the number of the plurality of SMIs reaching the DPC SMI storm threshold, the BIOS subsystem prevents use of a link to the first PCIe device and prevents an operating system from performing recovery operations to recover the first PCIe device from the error.

A secure one-time programming undo system includes a component and a component configuration system. A one-time programming subsystem in the component configuration system provides the component with personality configuration information that configures the component to perform component operations, and performs a one-time programming operation that configures a component engine in the component to deny modification requests to modify the personality configuration information. A one-time programming undo subsystem in the component configuration system performs a one-time programming undo authentication operation, and transmits a one-time programming undo instruction that is associated with the one-time programming undo authentication operation to the component, with the one-time programming undo authentication operation configured to authenticate the one-time programming undo instruction to the component such that the component executes the one-time programming undo instruction that reconfigures the component engine in the component to allow modification requests to modify the personality configuration information.

According to one embodiment, an Information Handling System (IHS) includes at least one storage unit that conforms to an NVMe specification and first and second BMCs. The BMCs are in communication with the storage unit and each configured with computer-executable instructions to negotiate with the second BMC, whether first or second BMC is to be an active BMC such that the other of the first or second BMCs becomes a passive BMC. When the first BMC is the active BMC, allow shared commands to be issued to a storage unit conforming to a Non-Volatile Memory Express (NVMe) specification; otherwise, inhibit the shared commands from being issued to the storage unit.

Redundant baseboard management controller (BMC) system and method

An information handling system bus port above a subject information handling system bus device may host an information handling system bus out of band message access control list of information handling system bus target device identifiers of other information handling system bus connected devices that the subject device is permitted to communicate with. The port may compare an information handling system bus target device identification field in out of band messages from the subject device to the list and route only out of band messages from the subject device in which the target device identification in the target device identification field is on the access control list through the information handling system bus. The port may discard (and generate error notifications, statuses, etc.) for out of band messages in which the target device identification in the target device identification field is not on the access control list.

A RAID storage controller storage-device-assisted data update system includes a RAID storage controller device coupled to a host system and RAID storage devices in a 'look aside' RAID storage controller device configuration. Based on command(s) from the RAID storage controller device, a first RAID primary data storage device may perform a first DMA operation to access first primary data stored on the host system, and write the first primary data to its first buffer subsystem. The first RAID primary data storage device may then perform a first XOR operation using the first primary data stored in its first buffer subsystem and second primary data stored in its first storage subsystem in order to produce first interim parity data, and write the first interim parity data to its second buffer subsystem. The first RAID primary data storage device may then update the second primary data with the first primary data.

An information handling system includes a host processing system, first and second data storage devices having respective first and second data storage capacities, and a license manager. The license manager implements a first license, receives a second license, and implements the second license without rebooting the information handling system. The first license defines a first configuration where the first data storage device is visible and the first data storage capacity is available to the host processing system, and the second data storage device is not visible and the second data storage capacity is not available to the host processing system. The second license defines a second configuration where both data storage devices are and both data storage capacities are available to the host processing system.

A RAID parity data generation offload system includes a RAID storage controller device that determines that a RAID parity data storage device loading for a RAID parity data storage device exceeds a loading threshold, and then generates and transmits a RAID parity data generation offload command associated with a RAID parity data update required in response to a RAID primary data update. A first RAID primary data storage device receives the RAID parity data generation offload command, and then retrieves current parity data from the RAID parity data storage device, and performs an XOR operation using the current parity data, current primary data, and updated primary data associated with the RAID primary data update in order to generate updated parity data. The first RAID primary data storage device then provides the updated parity data for storage on the RAID parity data storage device in place of the current parity data.

A RAID storage-device-assisted deferred parity data update system includes a RAID primary data drive that retrieves second primary data via a DMA operation from host system, and XOR's it with first primary data to produce first interim parity data, which causes a RAID storage controller device to provide an inconsistent parity stripe journal entry in the host system. The RAID primary data drive then retrieves third primary data via a DMA operation from the host system, XORs it with the second primary data and the first interim parity data to produce second interim parity data. A RAID parity data drive retrieves the second interim parity data via a DMA operation, and XORs it with first parity data to produce second parity data that it uses to overwrite the first parity data, which causes the RAID storage controller device to remove the inconsistent parity stripe journal entry from the host system.

Raid storage-device-assisted deferred parity data update system

A RAID storage-device-assisted data update system includes a RAID storage controller coupled to first RAID storage devices each including respective first RAID storage subsystems. Each first RAID storage devices receives a command from the RAID storage controller that identifies a second RAID buffer subsystem as a target memory location and, in response, retrieves respective first RAID storage device data from its respective first RAID storage subsystem and performs DMA operations to provide that first RAID storage device data on the second RAID buffer subsystem. A second RAID storage device that includes the second RAID buffer subsystem and a second RAID storage subsystem receives a command from the RAID storage controller and, in response, performs an XOR operation using the first RAID storage device data in the second RAID buffer subsystem to produce update data that it stores in its second RAID storage subsystem.

A hot-plugged PCIe device configuration system includes a PCIe device with a PCIe configuration space having PCIe configuration space registers. A computing system includes a PCIe connector and a PCIe setting record database storing a first PCIe setting record having a first register write location value and first register value information. The computing system detects that the PCIe device has been hot-plugged into the PCIe connector, and uses the first register write location value in the first PCIe setting record to determine a location in the PCIe configuration space that provides a first PCIe configuration space register. The computing system then uses the first register value information in the first PCIe setting record to determine at least one register value change for the first PCIe configuration register, and writes the at least one register value change to the first PCIe configuration space register using the location.
