摘要： A key retrieval system includes a management system and a managed system that is coupled to the management system through a network. The managed system includes a managed device, a management system configuration storage, a remote access controller device that stores a management system configuration for the management system in the management system configuration storage and provides a key management client subsystem that is configured to use the management system configuration to access the management system. The managed system also includes a BIOS. The BIOS detects an event that triggers unlocking the managed device. The BIOS determines that the remote access controller device is unavailable and, in response, retrieves the management system configuration and accesses the management system using the management system configuration. The BIOS then retrieves the locking key from the management system and unlocks the managed device using the locking key.

摘要： A system includes a management system, a managed system that is coupled to the management system through a network. The managed system comprises a managed device, a key identifier storage, a first managed device locking system coupled to the managed device and the key identifier storage, and a second managed device locking system coupled to the managed device, the key identifier storage, and the first managed device locking system. The first managed device locking system is configured to store a key identifier of the managed device in the key identifier storage and to provide access to a locking key of the managed device based upon the key identifier of the managed device, stored in a management system. The second managed device locking system is configured to monitor the managed device for an event that triggers unlocking the managed device, monitor operating status of the first managed device locking system. In some embodiments, where the first managed device locking system is unavailable, the second managed device locking system is configured to provide access to the locking key of the managed device based upon the key identifier of the managed device, stored in the management system.

摘要： A device-capability-based locking key management system includes a key management system coupled to a server device via a network. The server device includes storage devices coupled to a remote access controller device. The remote access controller device identifies each of the storage devices, and then identifies a key management profile for each of the storage devices. A first key management profile identified for at least one first storage device is different from a second key management profile identified for at least one second storage device. The remote access controller device then uses the respective key management profile identified for each of the storage devices to create a respective key management sub-client for each of the storage devices, and each respective key management sub-client communicates with the key management system to provide a locking key for its respective storage device.

摘要： Embodiments of systems and methods for providing configurable video redirection in a data center are discussed. In an embodiment, an Information Handling System (IHS) may include a Baseband Management Controller (BMC); and a memory coupled to the BMC, the memory having program instructions stored thereon that, upon execution by the BMC, cause the BMC to: receive a request from a remote client, where the request follows a first protocol; select one of a plurality of redirection components available to the IHS to populate a framebuffer with video frames using a second protocol; retrieve the video frames from the framebuffer; and transmit a response to the remote client following the first protocol, where the response comprises the video frames.

摘要： A redundant key management system includes a key management system coupled to a plurality of server devices through a network. A first server device includes a managed device coupled to a first remote access controller device that receive a device locking key from the key management system and uses it to lock the managed device. The first remote access controller device then encrypts the device locking key, broadcasts the encrypted device locking key through the network to a second remote access controller device in a second server device, and erases the device locking key. Subsequently, the first remote access controller device transmits a request to retrieve the encrypted device locking key. When the first remote access controller receives the encrypted device locking key from the second remote access controller device, it decrypts the encrypted device locking key and uses the resulting device locking key to unlock the managed device.

摘要： A system and method for dynamic discovery of web services for a management console is disclosed. The method includes detecting, at a discovery module of a service processor, a profile request from a console application. The method further includes requesting class information for the detected profile request from a provider register, and generating a profile-based web services description language (WSDL) file. The method also includes communicating the profile-based WSDL file to the console application.

摘要： A flexible display device monitoring system includes a display layer that is configured to flex into a plurality of flexed orientations. A sensor layer is coupled to the display layer and is configured to flex with the display layer into the plurality of flexed orientations. The sensor layer includes a plurality of sensors that each generate stress data in response to the sensor layer being flexed. A stress monitoring engine is coupled to the sensor layer and receives the stress data from the plurality of sensors when the sensor layer is flexed. The stress monitoring engine determines that the stress data exceeds a stress threshold and, in response, activates an alert system that may provide a vibration alert, a sound alert, or a visual alert. Visual alerts may include activating a relative portion on the display layer that corresponds to sensors that provided sensor data that exceeded the stress threshold.

摘要： A key management system includes a managed system coupled to a management system through a network. The managed system includes managed device locking subsystem(s) coupled to a managed device and a key storage. The managed device locking subsystem(s) retrieve, through the network from the management system, a managed device locking key that is configured to unlock the managed device. The managed device locking subsystem(s) then encrypt the managed device locking key to provide an encrypted managed device locking key, and store the encrypted managed device locking key in the key storage. Subsequent to storing the encrypted managed device locking key, the managed device locking subsystem(s) retrieve the encrypted managed device locking key from the key storage, and decrypt the encrypted managed device locking key to provide a decrypted managed device locking key. The managed device locking subsystem(s) then use the decrypted managed device locking key to unlock the managed device.
