Abstract: A method for record access in a distributed system includes receiving a request for a record, wherein the request comprises a transmitted key and a record identifier, extracting a location identifier and a transmitted pseudorandom portion from the transmitted key, obtaining a stored pseudorandom portion from a location in a key memory specified by the location identifier, and providing access to the record identified by the record identifier when the transmitted pseudorandom portion matches the stored pseudorandom portion.

Abstract: A system and method of dynamically managing a power supply allocation for each one of the server blades in a blade server includes a blade server system having a blade chassis, multiple server blades coupled to the blade chassis, a power supply system coupled to the blade chassis, a chassis management module coupled to the blade chassis, wherein the blade chassis includes electrical and data communication interconnections between the server blades, the redundant power supply system and the chassis management module. The chassis management module includes computer readable media having program instructions for dynamically managing a power supply allocation for each one of the server blades.

Abstract: A method for accurately tracking fault status in a computer system. The method includes storing a prior state for a sensor associated with a component of the computer system and receiving a sensor reading. When the prior state indicates the sensor was unavailable or unreadable such as when the component was removed, the method includes resending or re-emitting a faulty event to the fault diagnosing module, e.g., after reinsertion of the component in the computer system while it is still faulty. The method may include, prior to the triggering of the resending of the faulty event, determining that the sensor is in a non-nominal state. The method may also include storing in the data storage a definition of a nominal state for the sensor such that the determining the sensor is in the non-nominal state includes comparing one or more sensor readings with the nominal state definition.

Abstract: A digital ratiometric tracking filter provides superior measurement of the magnitude and phase of vibration of a rotating body, at uniform or non-uniform rotational speed. The sensed speed and vibration signals are concurrently processed and subsequently combined to produce the absolute magnitude and relative phase measurements. The concurrent processing of the sensed signals assures that any system-introduced errors are found in both signals and can be uniformly eliminated by the ratiometric processing thereof.
