Abstract: Disclosed herein is a system having a multi-processor configuration for electronics devices and systems, such as, computing and communication devices like laptop, notebook, tablets, smartphones, etc. In accordance with one embodiment of the subject matter the system comprises a plurality of processors and a multi protocol multi-root input output virtualization (MPMRIOV) switch communicatively coupled to at least one of the plurality of processors. The system further includes a peripheral and interface virtualization unit (PIVU) coupled to the MPMRIOV switch. In said embodiment, the PIVU is configured to communicatively couple at least one of the plurality of processors with at least one of a Peripheral Component Interconnect (PCI) compliant peripheral, a Peripheral Component Interconnect express (PCIe) compliant peripheral, a non PCI compliant peripheral, and a non PCIe compliant peripheral.

Abstract: A method handling a pluggable module selectable from a plurality of pluggable modules is executable at a media converter system of a network configuration. The method provides for automatically enabling of a disabled channel or disabling of an enabled channel of the media converter system when the pluggable module is attached to the media converter system, wherein the suggested channel enabling/disabling feature is executed on the basis of a correlation between module specific information extracted from the respective pluggable module and corresponding information extracted via the media converter system. An arrangement for executing the suggested method is also provided.

Abstract: A method for back-off retry with priority routing in a single, cohesive SAS expander includes routing a data transfer between an input of a single, cohesive SAS expander and an output of the single, cohesive SAS expander, wherein the single, cohesive expander includes a first SAS expander, and at least one additional SAS expander via at least one inter-expander link (IEL). The routing of data may further include routing a first OPEN request on a direct path through the first SAS expander to a port of a device and routing a second OPEN request on an alternate path from the first SAS expander and through a second SAS expander to the port of the device. The method further includes determining link availability between the second SAS expander and the port of the device, and, upon determination of a failed link or a busy link, re-routing the data transfer from the second SAS expander to the first SAS expander or a third SAS expander, or retrying the data transfer through the second SAS expander.
