A carrier that houses an external cable terminated at a male cable connector that mates with a female midplane connector on a midplane in a server blade computer is presented. The carrier includes side channel guides that align the carrier with the female midplane connector for a precise mating with the male cable connector. A light channel in the carrier captures light from a status light emitting diode (LED) at the midplane, and transmits that light to an externally visible end of the carrier.

In an aspect, a method is provided for using memory. The method includes the steps of (1) employing memory stacking, memory mirroring and memory interleaving in a total memory to reduce a number of memory entries that are written to an input/output (I/O) device while a portion of the total memory is replaced; and (2) storing data in the total memory. Numerous other aspects are provided.

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.

Detecting a fouled air filter in a computer equipment enclosure that includes an air filter, a supply plenum connecting the air filter and the computer equipment enclosure, a fan operating at a current fan speed, and a filter monitoring module connected for data communications to a management module. Detecting a fouled air filter according to embodiments of the present invention includes calculating, by the filter monitoring module, a pressure differential across the air filter; determining, for the current fan speed by the filter monitoring module in dependence upon a pressure differential profile for the air filter, whether the calculated pressure differential across the air filter exceeds a predetermined threshold value; and if the calculated pressure differential across the air filter exceeds the predetermined threshold value, reporting, by the filter monitoring module to the management module, that the calculated pressure differential across the air filter exceeds the predetermined threshold value.

A system on a computer for providing access to data stored on the computer in either power state is provided. The system can include a memory module and an external data interface connector. The system can further include a data interface controller for managing a data interface to the memory module and a data interface to the external data interface connector. The system can further include a multiplexer conductively connecting the data interface controller with the memory module when the computer is powered on, the multiplexer conductively disconnecting the data interface controller from the memory module when the computer is powered off and the multiplexer conductively connecting the external data interface connector with the memory module when the computer is powered on.

The invention is directed to a method and apparatus for automatically enabling replacement hardware. A method for automatically enabling hardware in accordance with an embodiment of the present invention includes: setting a presence bit of the hardware to a first value in response to a removal of the hardware from a socket; replacing the hardware into the socket; storing the first value of the presence bit in a memory; and automatically re-enabling the socket based on the stored first value of the presence bit for the socket or for assemblies containing the socket.

Methods and arrangements for managing interrupts in a processing system are disclosed. The method can determine an indication of an interrupt request from a peripheral entity, identify the peripheral entity associated with the indication, count occurrences of the indications; and flag the peripheral entity in response to the counted occurrences. When the counted occurrences reach a predetermined number in the predetermined time interval, interrupts from the peripheral entity can be ignored or the entity can be identified as having possible operational problems.

A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for managing interrupts in a processing system are disclosed. The design structure can determine an indication of an interrupt request from a peripheral entity, identify the peripheral entity associated with the indication, count occurrences of the indications; and flag the peripheral entity in response to the counted occurrences. When the counted occurrences reach a predetermined number in the predetermined time interval, interrupts from the peripheral entity can be ignored or the entity can be identified as having possible operational problems.
