Abstract: A system may implement a method for analyzing group level power supply unit efficiency based on information about power supply units (PSUs) that supply power to servers in a server group, and loads in the system. A group level PSU efficiency analyzer may collect PSU related information from respective management controllers on the servers, including PSU capacity, type, or vendor, efficiency tables, load information, or the current efficiency of each PSU (compared to the peak efficiency for the PSU). The analyzer may calculate the group level PSU efficiency by averaging the PSU efficiencies of the member PSUs or by calculating an average of the PSU efficiencies that is weighted based on load. The analyzer may identify changes to the system configuration (e.g., swapping the PSUs that power some servers) that would increase or maximize the group level PSU efficiency using, for example, a graph search or tree search.

Abstract: A support information provisioning system a support device, an external device; and a customer device. The customer device includes an external connector and a remote access controller device that is coupled to the external connector. In situations where the customer device is experiencing at least one customer device issue that prevents the customer device from provisioning support information related to the operation of the customer device, the remote access controller device operates to detect that the external device has been connected to the external connector and, in response, automatically cause new support information about that customer device to be generated. When the external device is subsequently connected to the support device, it may then provide that new support information to the support device for analysis.

Abstract: Serial Peripheral Interface (SPI) and a first remote access controller device located on the first motherboard and coupled to the first SPI. An off-motherboard SPI storage device is connected to the first SPI, and when the first remote access controller device determines that log entries have been generated, it automatically copies the log entries to the off-motherboard SPI storage device via the first SPI. A second motherboard includes a second SPI that couples to the off-motherboard SPI storage device when the second motherboard replaces the first motherboard in the chassis. A second remote access controller device located on the second motherboard and coupled to the second SPI will then retrieve the log entries that were automatically copied to the off-motherboard SPI storage device, and send the log entries through a network to a support device.

Abstract: An automated firewall-compliant customer support resolution provisioning system includes a customer support system coupled to a customer device. The customer support system receives a first secure request from the customer device that identifies an event in the customer device and, in response, sends a first secure response through a firewall subsystem to the customer device within a first timeout period enforced by the firewall subsystem. The customer support system then determines event resolution information for the event. Subsequent to the first timeout period and based on the first secure response, the customer device sends a second secure request to the customer support system requesting the event resolution and the customer support system sends the event resolution information through the firewall subsystem to the customer device within a second timeout period enforced by the firewall subsystem. The customer device then utilizes the event resolution information to address the event.

Abstract: Identity context-based access control is implemented by generating an identity context expression from user identity data. In particular, users are clustered based on combinations of one or more attributes. These clusters comprise one or more identity context(s). Preferably, an intersection of attribute sets of each user in the cluster is formed. In addition, an intersection of attribute sets of each user not in the cluster also is formed. If the attribute set that is common across the cluster of users is not a subset of the attribute set that is common across the rest of the users, then the attribute set forms a unique identity context expression. To reduce the number of roles used in role-based access control (RBAC), at least one role is replaced with an identity context expression. Run-time access control is then enabled.
