Abstract: An apparatus for reducing electromagnetic interference in an electronic system, comprises a switch coupled to a conductive line, and a system management device that can be coupled to the electronic system. The system management device detects whether a device is connected in a particular location in the system, and opens the switch to disable data transmission a long the conductive line to the particular location when the device is not connected. Noise signals are thus prevented from being propagated on transmission lines that are not terminated, and EMI that can be generated by signal reflections on the unterminated conductive line is substantially reduced, if not eliminated.

Abstract: In a system and method for managing the performance of a bladed computer system, a management blade identifies one or more individual blades in a chassis. The management blade then automatically determines an optimal performance configuration for each of the individual blades and provides information about the determined optimal performance configuration for each of the individual blades to a service manager. Within the service manager, the information about the determined optimal performance configuration is processed and an individual frequency is set for at least one of the individual blades using the information processed within the service manager.

Abstract: In a system, method and apparatus for the frequency management of processors in a multi-processor (MP) computer system, a first processor requiring a first level of performance is operated at a specific frequency and consumes a portion of the thermal and power budget. A second processor requiring a second level of performance is operated at a second specific frequency and consumes a portion of the thermal and power budget. The overall power and thermal budget in the multi-processor computer system is maintained under the different operating frequencies.

Abstract: In a blade-based computer system, the number of loaded blades in the system is determined. Next, an optimal performance configuration for each of the individual blades is determined. The optimal performance configuration is based at least in part on the number of the blades loaded in the chassis and the overall thermal and power envelope. Then an individual frequency for at least one of said individual blades is set creating a more efficiently run system.

Abstract: A method of optimizing performance of a memory subsystem in a computer system. This method including the step of informing the computer system of what type of memory module loading is present in the memory subsystem. The method also includes operating the memory subsystem at a first frequency that is at a chosen ratio to a second frequency at which a frontside bus (FSB) operates. Further, the method includes optimizing the performance of the memory subsystem by changing the ratio.

Abstract: In a system, method and apparatus for managing the operating frequency of blades in a blade-based computer system based upon performance requirements, a first blade that requires a specific power allocation is operated at a specific frequency and consumes a portion of the thermal and power budget for the blade-based computer system. A second blade that requires a specific power allocation is operated at a specific frequency and consumes a portion of the thermal and power budget for the blade-based computer system. Additionally, the overall power and thermal budget of the blade-based computer system is maintained.

Abstract: In a system and method for the frequency management of processors or blades to allow capacity on demand a requestor of the computer system develops a need for an increased performance from the computer system. The requester then sends a request to the grantor of the computer for an increase in the computer performance. If the grantor authorizes the request, the grantor sends the requestor the requisite information needed to increase the frequency associated with blades or processors in the computer system. The computer system is then operated at an increased frequency to satisfy the demand.
