Abstract: A hybrid cluster system includes at least one computing node for providing computing resources and at least one storage node for providing storage resources. A specification of the at least one computing node is identical to a specification of the at least one storage node.

Abstract: The present disclosure relates to a method for testing connectivity. The method is applied to an electronic equipment which is disposed include two test units (e.g. network interface controller, RJ-45 connector) and a network transformer. The test unit couple to the network transformer so that can send a high frequency test signal or a low frequency test signal to the network transformer respectively. When the test unit receives a low frequency response signal, it means correspond internal circuitry of the network transformer does not have a open circuit fault. When the test unit does not receive a high frequency response signal, it means correspond pins of the network transformer does not have a short circuit fault.

Abstract: A signal simulation device, a signal recording and simulation testing method for capturing a testing signal sent out by a test host and sending out a corresponding testing signal to a to-be-tested device. The signal simulation device comprises an input interface, a timer, a processing unit and a signal capturing unit. The signal capturing unit is electrically connected to the input interface, the timer and the processing unit. The testing signal is recorded by the signal capturing unit through the input interface. When the signal simulation device is switched to a recording status, the signal simulation device is electrically connected to the test host through the input interface to receive the testing signal. The clock cycle of the timer is adjusted according to the testing signal. The processing unit is used for setting the clock cycle of the timer.
