Abstract: A method includes identifying, from among nodes within a multi-node system, a node that has a security setting satisfying a security setting criteria, booting the multi-node system with the identified node as the primary node, and operating the multi-node system using the security setting of the identified node. Accordingly, the method may provide dynamic selection of a primary node based upon the security setting criteria and the security settings of the nodes within the multi-node system. Optionally, the security setting of each node is stored in a trusted platform module. In non-limiting examples, the security setting criteria may be the highest security setting among all nodes within the multi-node system or a predetermined minimum security setting, such as a trusted execution technology setting.

Abstract: A method and/or computer program product automatically adjusts room temperature in a data center room. A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system. The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices. In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system.

Abstract: A computer system comprises a Trusted Platform Module System (TPMS). The TPMS comprises a first Trusted Platform Module (TPM) and a second TPM, which comports with a different TPM specification than that followed by the first TPM. A physical presence input device receives a local physical change signal that proves a local physical presence of a user at the computer system. A toggle input device, which requires the local physical change signal, causes the state being output from the GPIO pin on the first TPM to switch from a first state to a second state. This change of state causes a TPM switch to selectively decouple the first TPM from a central processing unit and to couple the second TPM to the central processing unit.
