A method of populating page tables of an executing workload during migration of the executing workload from a source host to a destination host includes the steps of: before resuming the workload at the destination host, populating the page tables of the workload at the destination host, wherein the populating comprises inserting mappings from virtual addresses of the workload to physical addresses of system memory of the destination host; and upon completion of populating the page tables, resuming the workload at the destination host.

This disclosure is directed to a computer-implemented method, systems, and devices to migrate a virtual fibre channel (VFC) connection from a first hardware communication path to a second hardware communication path within a fibre channel (FC) network prior to failure of a device in the first hardware communication path. For example, a hypervisor database may contain health status with respect to recoverable failure incidents across host bus adaptor (HBA) ports for a source HBA port and a target HBA port associated with a first VFC connection using the first hardware communication path. If it is determined that a number of recoverable failure incidents on at least one component in the first hardware communication path has occurred, migration of the first VFC connection from the first hardware communication path to a second hardware communication path may be initiated prior to actual hard failure.

Examples may forward an input/output (IO) request with use of kernel-level instructions. Examples may receive the IO request via a port of a standby controller, generate an alternate version of the IO request using at least kernel-level instructions of the standby controller, and provide the alternate version of the IO request to physical memory of the active controller by providing the alternate version of the IO request to a designated region of physical memory of the standby controller that is mapped to a designated region of the physical memory of the active controller.

An information processing apparatus includes a processor and a memory storing instructions. Executing the instructions by the processor causes the processor to perform operations. A virtual device on the information processing apparatus to transmit a print job to an image forming apparatus is selected. A user interface is displayed that is for activating, in accordance with the selected virtual device and among one or more applications to provide an additional function to the image forming apparatus, an application that corresponds to a model of the image forming apparatus to which the selected virtual device transmits the print job.

Disclosed are various approaches for decreasing the latency involved in reading pages from swap devices. These approaches can include setting a first queue in the plurality of queues as a highest priority queue and a second queue in the plurality of queues as a low priority queue. Then, an input/output (I/O) request for an address in memory can be received. The type of the I/O request can be determined, and then the I/O request can be assigned to the first queue or the second queue of the swap device based at least in part on the type of the I/O request

A communication device for connection with a power source and a host device is provided. The communication device comprises a device controller and a converter circuit. The device controller is adapted for data communication with the host device and the converter circuit is configured to provide a virtual device ground at least to the device controller, so as to compensate a ground potential difference between the host device and the communication device.

A clustered storage system may include potentially many different nodes, each including a storage driver and a scheduler agent. A node may mount a virtual storage volume for the use of a container application at the node. When a master node receives a request to instantiate a new containerized application, a scheduler at the master node may determine prioritization information for the new containerized application. The prioritization information may prioritize one or more nodes at which a virtualized storage volume employed by the application container instance is mounted.

A system and method for visualizing multiple datasets in a virtual 3-dimensional interactive environment. Multiple datasets may be related and virtually cast as 3-dimensional type structures. User interfaces, such as game controllers or headsets, may be used to present the dataset from differing perspectives including the appearance of moving through the data. Certain embodiments provide for mirror image views that allow for presentation of higher order datasets. Other embodiments provide for animation or motion indicia to show how the data is changing and the results on the display. The datasets may represent physical areas or virtual areas as well as demographic, sensors and financial information.

In a computer system, when a first high availability (HA) pair is configured with a first logical device of a first storage apparatus and a second logical device of a second storage apparatus, the first logical device is virtualized on a third storage apparatus and is set to correspond with a third logical device of the third storage apparatus. A fourth storage apparatus virtualizes the second logical device and sets the second logical device to correspond with a fourth logical device of the fourth storage apparatus. After a second HA pair is configured with the third logical device and the fourth logical device, the data on the first logical device is migrated to the third storage apparatus and managed as data on the third logical device. The data on the second logical device is migrated to the fourth storage apparatus and managed as data on the fourth logical device.

In some examples, there is provided a method for a storage controller to receive a request to write data at a virtual location, writing data at the next free physical location in sequence, writing metadata correlating the virtual location with the physical location at the physical location, and writing a counter at the physical location. The recorded metadata can be used to re-construct the mapping between a given physical location and its corresponding virtual location if the virtual block address is somehow lost. The recorded counter can be used to determine the most recently recorded mapping between the virtual location and physical location, thereby resolving any discrepancies between earlier recorded metadata.
