Abstract: Methods, apparatus, and products for managing virtual addresses of blade servers in a data center are disclosed that include storing by a blade server management module (‘BSMM’), in non-volatile memory of a blade server, a parameter block, the parameter block including one or more virtual addresses for communications adapters of the blade server and one or more action identifiers, each action identifier representing a type of address modification; detecting, by a basic input-output system (‘BIOS’) module of the blade server upon powering on the blade server, the parameter block; and modifying, by the BIOS module of the blade server in dependence upon the one or more action identifiers of the parameter block, an address of at least one communications adapter of the blade server.

Abstract: Embodiments of the invention address deficiencies of the art in respect to boot ROM handling and provide a method, system and computer program product for optimized boot ROM handling for I/O devices. In one embodiment of the invention, a ROM scan area optimization method can be provided. The method can include pre-processing multiple boot ROM images to determine memory space requirements in the ROM scan area for all of the boot ROM images. The method further can include partitioning the ROM scan area into multiple, different static portions and at least one dynamic paged portion. Finally, the method can include generating an optimal arrangement of the boot ROM images defining placement of some of the boot ROM images in corresponding ones of the static portions, and others of the boot ROM images in the dynamic paged portion.

Abstract: A method and system are disclosed to enable and control power reduction in a blade/chassis system. A “maximum power reduction” attribute is stored in the VPD of the blade (or can otherwise be input to or retrieved or calculated by the management entity). The management module of the chassis in which the blades and power supplies are located uses this information to manage the power reduction of blades when the system is operating in an over-subscription mode and a power supply fails. If throttling is required, the system knows the amount of power reduction available for each blade and controls the throttling by spreading it out among the blades in the system so that, ideally, no blade will cease operation altogether.

Abstract: A jumper including a connecting face, a light-emitting face, and a light pipe extending from the connecting face to the light-emitting face is provided. The light pipe is operable to transmit a light from a provided computer hardware from the connecting face to the light-emitting face responsive to the jumper forming a circuit with the provided computer hardware. A method for fabricating a jumper is also provided. The method includes forming a plurality of receptacles on a connecting face of the jumper and incorporating a light pipe into the jumper such that the light pipe extends from the connecting face of the jumper to a light-emitting face of the jumper. A method for providing jumper installation feedback is further provided. The method includes mounting a jumper on a provided computer hardware and transmitting a light through the jumper responsive to the jumper forming a circuit with the provided computer hardware.

Abstract: A flash memory is provided that includes a primary flash bank and a secondary flash bank. The primary flash bank includes CRTM logic and BIOS logic and the secondary flash bank comprises a backup copy of the CRTM logic and the BIOS logic. A switching mechanism is configured to selectively activate the primary flash bank or the secondary flash bank.

Abstract: A method, system, and program product supporting dynamic configuring of a multi-node computer. The system includes a scalability management module directly coupled to each node in the multi-node computer.

Abstract: The present invention provides a method and system for providing a reset after an operating system (OS) hang condition in a computer system, the computer system including an interrupt handler not accessible by the OS. The method includes determining if an interrupt has been generated by a watchdog timer; monitoring for an OS hang condition by the interrupt handler if the interrupt has been generated and after it is known that the OS is operating; and resetting the OS if a device driver within the OS has not set a bit in a register, the bit for indicating that the OS is operating. The method and system in accordance with the present invention uses existing hardware and software within a computer system to reset the OS. The present invention uses a method by which a critical hardware watchdog periodically wakes a critical interrupt handler of the computer system.
