Methods and systems for supporting similar thermal devices may involve collecting, by a thermal module on a management controller of an information handling system, device information about an add-in card, determining whether the add-in card was previously defined by matching the device against a table, searching the table based on the determination that the add-in card was not previously defined, determining whether the add-in card is supported by finding a match in the table, and applying a thermal tier associated with the match in the table based on the determination that the add-in card is supported. The device information collected may involve at least two of a reseller part number, description, device identifier, sub device identifier, vendor identifier, sub vendor identifier, slot identifier, lane width, and auxiliary power indicator. The search of the table may involve at least one of the description, lane width, and sub vendor identifier.

Server information handling system LED indication lights and other illumination devices are selectively illuminated based upon override configuration settings pushed down from a data center administrative tool. A chassis management controller that manages a blade or rack with plural server information handling systems overrides indication light illumination at blade or rack components, such as power supply and I/O modules. Power saved by reducing indication light illumination is allocated to support operation of one or more server information handling systems.

A method of thermal control in a chassis is presented. An example method of thermal control can include each of one or more blades reporting a requested fan blade speed to a CMC controller where the CMC controller performs an auction of the requested fan blade speed, determines a high value and assigning a corresponding active blade, and reporting the high value to the blades. The active blade then provides fan speed alerts while the passive blades provide fan speed alerts only when the new fan speed request exceeds the high value.

A method and system provide local key management for storage enclosures. The method includes retrieving first security content from a security vault of a service processor, then dynamically detecting a hardware interface communicatively coupled to the service processor. A data storage device, communicatively coupled to the hardware interface is dynamically detected. A dynamic determination is made as to whether the data storage device is a self-encrypting capable data storage device. In response to the data storage device being a self-encrypting capable data storage device, a second security content is retrieved from the data storage device, and a validation regarding an association between the first security content and the second security content is made. Finally, in response to a positive validation of the association between the first security content and the second security content, security keys are transmitted to the data storage device, and access to the data storage device is enabled.

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.
