Abstract: A method for testing a serial over local area network (SOL) function of a motherboard of a computing device. The method determines that the SOL function is normal if forward data can be transmitted from the serial port of the motherboard to a network interface controller (NIC) of the motherboard through a predefined path, and backward data can be transmitted from the NIC to the serial port through a predefined reverse path. The method determines that the SOL function is abnormal if the forward data cannot be transmitted from the serial port to the NIC through the predefined path, or the backward data cannot be transmitted from the NIC to the serial port through the predefined reverse path.

Abstract: Approaches for problem determination and resolution process cross communication are provided. Embodiments provide cross communication of a problem determination and resolution among similar data center devices. Specifically, symptoms of an error condition encountered for one data center device are captured by a first enterprise group, along with an associated resolution solution, and made available to an another enterprise group managing a commonly configured data center device, which may be faced with a similar error condition.

Abstract: A method begins by a processing module receiving a large data file for storage in a dispersed storage network (DSN) and determining initial dispersed storage error encoding parameters. The method continues with the processing module encoding, during a first time interval of receiving the large data file, first data segments of the large data file using the initial dispersed storage error encoding parameters to produce a first plurality of sets of encoded data slices. The method continues with the processing module writing the first plurality of sets of encoded data slices to the DSN and monitoring processing of the writing to produce first write processing performance information. When the first write processing performance information compares unfavorably to a desired write performance range, the method continues with the processing module adjusting, for a second time interval, the initial dispersed storage error encoding parameters to produce adjusted dispersed storage error encoding parameters.

Abstract: The invention is a method of operating a system having multiple finite state machines and a controller. Each finite state machine enters an offline state upon detection of anomalous operation. The controller detects whether all finite state machines are offline. The controller transmits an online activation event signal to each finite state machine when all are offline. Each finite state machine evaluates entering the online state if current conditions permit. Reentering the online state includes loading a predetermined set of operating parameters. The finite state machines are responsive only to a reset event and an online activation event when in the offline state.

At least one special PHY test sequence is transmitted to the asymmetrical interconnect interface during link start up to place the device under test in PHY testing mode in which the TGA is used to generate and analyze data. The asymmetrical interconnect interface can then receive a configuration command and configure the asymmetrical interconnect interface in response to the configuration command. The asymmetrical interconnect interface can then use the TGA to transmit test sequences to, or receive test sequences from, e.g., a tester, on at least one identified lane of the asymmetrical interconnect device, which at least one identified lane is set by the configuration command.

Abstract: Instead of disabling PCI communication between system resources in a host computing device and I/O devices when a PCI Host Bridge (PHB) is unable to function, the host computing device may include a redundant PCI communication path for maintaining communication between the system resources and the I/O devices after a first PHB experiences an unrecoverable error. In one embodiment, the redundant PCI communication path includes a second PHB that is maintained in a standby state so long as the first PHB is functioning normally. However, once the first PHB experiences an unrecoverable error, the second PHB is changed to the master state and assumes the responsibility for maintaining communication between the system resources and the I/O devices.
