    摘要： An information handling system may include a processor, one or more accelerators communicatively coupled to the processor, and a management controller communicatively coupled to the processor and the one or more accelerators and configured for out-of-band management of the information handling system, the management controller further configured to receive information regarding the one or more accelerators, determine a criticality factor for each of the one or more accelerators based on the information, determine an accelerator health status for each of the one or more accelerators, and determine an overall system health of the information handling system based on the criticality factors and the accelerator health statuses.

    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.

    摘要： A system and method are disclosed for delegating, by a resource-constrained device, a privilege to a basic input/output system, wherein the privilege allows the basic input/output system to authenticate an endpoint device on behalf of the resource-constrained device. The system and method also includes generating an asymmetric security key that includes a private key and a public key and transmitting the public key to the basic input/output system, wherein the public key is included in a proxy certificate generated by the basic input/output system. In addition, the system and method includes establishing a secure session between the basic input/output system and the endpoint device using the private key and the proxy certificate, wherein the secure session is used by the basic input/output system to authenticate and verify that the endpoint device is authorized to perform an operation.

    摘要： 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.
