Abstract: Systems and methods include a remote access controller of an IHS (Information Handling System) that provides remote management of the IHS. The remote access controller initiates an update of firmware used to operate a hardware component of the IHS by transmitting a firmware image to the hardware component via a first signaling pathway connecting the remote access controller to the hardware component. The remote access controller detects a failure in transmission of the firmware image to the hardware component via the first signaling pathway and identifies a second signaling pathway connecting the remote access controller to the hardware component. The remote access controller resumes transmission of the firmware image to the hardware component via the second signaling pathway and the firmware used to operate the hardware component is updated using the transmitted firmware image.

Abstract: Systems and methods provide multi-channel transmission of a firmware image to a hardware component of an IHS (Information Handling System), where the firmware image is transmitted by a remote access controller of the IHS that supports remote management of the IHS. Upon a firmware being initiated, the remote access controller determines an available bandwidth of a first signaling pathway of the hardware component and also determines an available bandwidth of a second signaling pathway of the hardware component. One portion of the firmware image is transmitted to the hardware component using the first signaling pathway, where a size of that portion is selected based on the available bandwidth of the first signaling pathway. Another portion of the firmware image is transmitted to the hardware component using the second signaling pathway, where a size of that portion is selected based on the available bandwidth of the second signaling pathway.

Abstract: Periods of interoperability of sideband buses prevent effective management of managed devices by a remote access controller. Embodiments avoid periods of inoperability of sideband buses and recover the sideband bus without resetting the managed devices or the IHS (Information Handling System). The remote access controller configures timer and transmits the timer to a managed device. The managed device monitors the sideband for messages for the remote access controller. If no messages are received before expiration of the timer, the managed device resets its sideband bus endpoint, without resetting the managed device.

Abstract: An information handling system provides configuration, monitoring, and inventory services between an application programming interface service hosted by the information handling system and a remote client. The system communicates using application program interfaces exposed by the application programming interface service with a device associated with the information handling system, and packages data received from the device via the application programming interface service before transmitting the data to the remote client.

Abstract: Systems and methods prevent nonsecure updates to firmware of an IHS (Information Handling System). During factory provisioning of the IHS, a manifest of firmware loaded for operating a hardware component of the IHS is digitally signed by a remote access controller of the IHS, and the signed manifest is stored to the IHS. Once the IHS has been deployed and during an interval where the IHS does not have access to external networks by which to validate a received firmware update, the signed manifest of loaded firmware is retrieved and used to determine whether the received firmware update is compatible with the loaded firmware of the hardware component. When the update is compatible with the loaded firmware, at least a portion of the loaded firmware is replaced with the firmware update and an updated manifest is digitally signed to reflect availability of the update for use by the hardware component.

Abstract: On power-up, self-encrypting drives (SEDs, 150) are unlocked one after another in an order based on the SEDs' unlocking priorities. In determining the priorities, one or more of the following factors are taken into account: (1) the content stored on the SEDs; the SEDs storing the OS are given higher priorities; (2) the SEDs' access history on previous power-ups: if a SED was accessed earlier than other SEDs, then this SED is given a higher priority; (3) whether there is an access request pending for a SED. Such prioritization allows the system to reach full functionality faster on power-ups. Other features are also provided.

Abstract: Systems and methods for managing Serial Attached Small Computer System Interface (SAS) traffic with storage monitoring are described. In some embodiments, an Information Handling System (IHS) may include an embedded controller (EC) and a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution, cause the EC to: designate a first Baseband Management Controller (BMC) as active; designate a second BMC as passive; and receive, from the active BMC, monitoring data relating to one or more of a plurality of storage devices without receiving the monitoring data from the passive BMC.

Abstract: In various embodiments, a remote access controller supporting remote management of an Information Handling System (IHS). The remote access controller receives a first firmware image comprising first firmware for a first hardware component of the IHS. A personality of the first firmware is determined and at least a portion of the first firmware is stored to a first region of a persistent storage of the first hardware component, where the first region is designated as storing firmware for adapting the first hardware component to the first personality. In response to a detected reconfiguration of the IHS, the remote access controller generates a notification of the first firmware that is stored by the first hardware component and that is usable to adapt operation of the first hardware component to the first personality.
