One embodiment of the present invention provides a system that determines the complexity of a transaction between a first entity and a second entity. The system starts by determining a first probability of success for a portion of the transaction which is associated with actions of the first entity. The system then determines a second probability of success for a portion of the transaction which is associated with actions of the second entity. The system next calculates a transactional complexity for the transaction based on the first probability of success and the second probability of success.

Some embodiments of the present invention provide a system that prolongs a remaining useful life of a power supply in a computer system. First, performance parameters of the power supply are monitored. Next, the remaining useful life of the power supply is predicted based on the monitored performance parameters. Then, an operational regime of the power supply is adjusted based on the predicted remaining useful life to prolong the remaining useful life.

Some embodiments of the present invention provide a system that generates a simulated vibration pattern in a computer subsystem. During operation, a vibration pattern is monitored at a location in the computer subsystem, wherein the vibration pattern is monitored while the computer subsystem is incorporated into the computer system and the computer system is operating. Then, the vibrations of the computer subsystem are mimicked by generating the simulated vibration pattern at the same location in the computer subsystem based on the monitored vibration pattern.

Some embodiments of the present invention provide a system that controls a device that generates vibrations in a computer system. During operation, a critical vibration frequency is determined for the computer system. Next, a keep-out zone is generated based on the critical vibration frequency, wherein the keep-out zone specifies a range of frequencies to be avoided. Then, the device is controlled based on the keep-out zone to reduce vibrations generated by the device in the keep-out zone.

Some embodiments of the present invention provide a system that includes a drive carrier for a hard disk drive (HDD) and one or more vibration control clips affixed to the drive carrier. Within this system, a mode of vibration of the HDD is modulated by contact between each of the vibration control clips and a surface within the computer system.

A system that generates an electromagnetic interference (EMI) fingerprint for a computer system is presented. During operation, the system executes a load script on the computer system, wherein the load script includes a specified sequence of operations. Next, the system receives EMI signals generated by the computer system while executing the load script. The system then generates the EMI fingerprint from the received EMI signals.

Some embodiments of the present invention provide a system that assures stability of the speed of a cooling fan in a computer system. During operation, a temperature of the computer system, an ambient temperature, and a current fan speed for the cooling fan are monitored. Next, a validated ambient temperature based on parameters including the temperature of the computer system, the ambient temperature, and the current fan speed is computed. Then, a control signal is generated in response to the validated ambient temperature, and the control signal is sent to the cooling fan to assure stability of the fan speed of the cooling fan.

Some embodiments of the present invention provide a system that determines whether a cooling device in a computer system is responsive to control signals. During operation of the computer system, a control signal is sent to the cooling device. Next, a response of the computer system to the control signal is measured, wherein the response includes a temperature profile. The frequency content of the control signal is then compared to the frequency content of the temperature profile to determine whether the cooling device is responsive to the control signal.

Some embodiments of the present invention provide a system that stores telemetry data from a computer system. The system includes a first buffer, a second buffer, and a third buffer. During operation, the system periodically obtains the telemetry data from the computer system and stores the telemetry data in the first buffer, second buffer, and third buffer. The system also compresses the telemetry data in the first and second buffers. To compress the data, the system creates a first set of summary statistics from the telemetry data in the first buffer and the second buffer and stores the first set of summary statistics in the first buffer, which becomes a historical data buffer.

Embodiments of the present invention provide a system for preventing dust-fouling in a computer system. During operation of the computer system, the system monitors the computer system and determines if the computer system is becoming dust-fouled. If so, the system reverses fans in the computer system to circulate air through the computer system in the opposite direction to dislodge and disperse dust from the computer system.
