Abstract: A Peripheral Component Interconnect-Express (PCIe) port includes a PCIe link, a pending transaction counter, and an error status register. The PCIe port operates to issue a transaction on the PCIe link, determine that an endpoint device has become uncoupled from the PCIe link after issuing the first transaction, determine that a value stored in the pending transaction counter is not equal to zero in response to determining that the endpoint device has become uncoupled, and set an error bit in the error status register in response to determining that the first value is not equal to zero.

Abstract: A method of using an information handling system can include communicating accessibility of a resource to a grid system, powering down the information handling system, receiving a wake request from the grid system, booting the information handling system into a grid mode where the resource is accessible to the grid system. Machine-executable code for an information handling system can include a method for indicating that a resource in the information handling system is accessible to a grid system, communicating that the resource is accessible to the grid system, and placing the information handling system into a low power state. An information handling system can include a processor that can indicate that a resource is accessible to a grid system, communicate to the grid system that the resource is accessible, and place the information handling system into a low power state.

Abstract: A method of routing data in an information handling system can include receiving a notification from a management controller at a basic input/output system (BIOS) that includes a system management interrupt (SMI) handler. The a notification can indicate that the management controller has a data packet bound for a peripheral component interconnect express input/output (PCIe I/O) device coupled to a secondary processor. The method can include generating a system management interrupt at the information handling system via the BIOS SMI handler in response to the notification. The method can also include retrieving the data packet from the management controller via the BIOS SMI handler and sending a payload associated with the data packet from the BIOS SMI handler to the PCIe I/O device.

Abstract: For backing up of data from a source to a destination, a virtual tape library (VTL) appliance intercepts a message for backing up the data. In response to the intercepted message, the VTL appliance sends a command to initiate the backing up of the data. A network attached storage (NAS) server, which is the source of the data and is coupled to the VTL appliance by a network, receives the command. An agent located in the NAS server is triggered in response to the command to directly transfer the data from the source to the destination. The agent informs the VTL appliance upon completion of the transfer of the data.

Abstract: A method for virtualizing input/output whereby a back-end driver component running back-end in a privileged operating system address space configures an input/output adapter through a setup/control path is disclosed. The back-end driver component is used to register with the input/output adapter to allow for the receipt of information concerning a catastrophic event. Catastrophic event data is transmitted to an active front-end driver component running in a guest operating system address space, where a communication path was established between the active front-end driver component and the back-end driver component. The back-end driver component listens for requests from the active front-end driver component. Upon receipt, an input/output context association is established between an input/output context in the input/output adapter and the active front-end driver component.
