A device, having a safe state, is coupleable to a communication bus. The device includes a first logic unit; a second logic unit; a monitoring circuit; a transmission unit; and a first test line. The device is adapted such that the first logic unit communicates with a bus via the transmission unit in a communication phase and the monitoring circuit emits a monitoring signal to the transmission unit upon a fault so that the transmission unit blocks the communication. The first and/or the second logic unit is coupled to the monitoring circuit via the first test line so as to emit a first test signal to the monitoring circuit.

A bus monitoring system, a method and an apparatus, wherein the system comprises: a bus node; a bus monitoring module configured to monitor a first bus where the bus monitoring module is located to generate monitoring information; an information storage module configured to acquire the monitoring information from the bus monitoring module through a second bus; the first bus being configured to connect a master device and a slave device of the bus node; the second bus being configured to connect the information storage module and the bus monitoring module, wherein the second bus is independent from the first bus. By means of the present disclosure, the technical problem that bus monitoring information cannot be acquired when bus exception occurs in the related art is solved.

A method for modifying a configuration of a storage system. The method includes one or more computer processors identifying data received at a logical partition (LPAR) of a storage system, wherein a copy program associated with a process for data mirroring executes within the LPAR. The method further includes determining a first rate based on analyzing a quantity of data received at the LPAR during the process of data mirroring. The method further includes creating a journal file from a set of records within the received data. The method further includes determining a second rate related to migrating the journal file from the LPAR to intermediate storage included in the storage system. The method further includes determining to modify a set of configuration information associated with the process of data mirroring by the storage system based, at least in part, on the first rate and the second rate.

Embodiments are described for a heuristic configuration selection process as part of or accessible by the backup management process. This processing component provides a method to automatically determine the configuration parameters needed to obtain optimal performance for a given backup/restore job. This process involves identifying key parameters that determine backup performance and suggest means to derive and incorporate those configurable parameters into the backup software automatically. Embodiments can be applied to stream based backups, or other types of backup software as well.

The system, method, and computer program product described herein provide ways to modify a user interface when a performance of the user interface degrades due to lack of resources including presenting the user interface to a user that includes a first element that requires an allocation of a first amount of resources of a server to perform a function, determining that a performance of the user interface has degraded below a threshold amount, in response to determining that the performance has degraded, identifying a second element that requires an allocation of a second amount of resources of the server to perform the function where the second amount of resources is smaller than the first amount of resources, and replacing the first element with the second element to reduce the required amount of resources that are allocated by the server to the user interface.

An information processing apparatus includes a receiving unit that receives information indicative of a priority of communication designated by a user who uses a communication line available to plural users and information indicative of a bandwidth of a priority target designated by the user; and an allocated bandwidth deciding unit that decides an allocated bandwidth allocated to the user on a basis of evaluation of the priority and the bandwidth of the priority target.

Aspects of the invention include efficient generation of instrumentation data for direct memory access operations. A non-limiting example apparatus includes an instrumentation component, residing in a cache in communication with a plurality of processing units, an accelerator, and a plurality of input output interfaces. The cache includes a direct memory access monitor that receives events from the accelerator its respective I/O interface and stores DMA state and latency for each event. The cache also includes a bucket including a DMA counter and a latency counter in communication with the DMA monitor, wherein the bucket stores in the DMA counter a count of DMAs coming from a source and stores in the latency counter the latency measured for each DMA coming from the source.

A bus data analysis method comprises the steps of receiving an input signal, decoding the input signal according to a protocol, thereby extracting a data signal from the input signal, and analyzing the data signal extracted from the input signal statistically, thereby generating a statistically analyzed data signal. Furthermore, a bus data analysis system is described.

An FPGA upgrade method is provided, including: delivering, by a host, an upgrade instruction to an FPGA; uninstalling a PCIe driver corresponding to the FPGA to let a status of the PCIe link be changed to link down; continuously monitoring, in a first expiration time, whether the status of the PCIe link is changed to link up; and if yes, reloading the PCIe driver. The method further includes: after the FPGA receives the upgrade instruction, continuously monitoring, in a second expiration time, whether the status of the PCIe link is changed to link down, if yes, loading the configuration data from the FPGA configuration memory for upgrade; and after upgrade is completed, negotiating, by the FPGA, with the host to restore the status of the PCIe link to link up that is used for reloading the PCIe driver upon detection by the host.
