  • Patent number: 10261933
    Abstract: Session level restrictions can be implemented for devices having disjoint stacks. When a filter driver is loaded onto a device stack, it can traverse the device stack to locate the root driver in the stack. If the root driver is a redirection virtual bus driver, the filter driver can obtain a session identifier associated with the device. Otherwise, if the root driver is not a redirection virtual bus driver, the filter driver can obtain the container ID for the device. The filter driver can then obtain a list of the devices that are enumerated by the redirection virtual bus driver and determine whether any of the devices in the list have a container ID matching the container ID of the device. If a match is found, the session ID of the matching device can be obtained and employed to implement session level restrictions.

  • Patent number: 10078609
    Abstract: A non-USB device can be virtualized as a USB device. When a non-USB device is connected to a client terminal, a filter driver can be employed to cause the non-USB device to be treated as a USB device to thereby allow the device to be redirected using USB device redirection techniques. When an I/O request is sent to the redirected device, the request will be in USB format since the server-side components will view the redirected device as a USB device. Then, the I/O request can be converted from the USB format into a format suitable for the non-USB device. Any response generated by the non-USB device can be converted to USB format in a similar manner. As a result, non-USB devices can be redirected without altering any of the existing server-side VDI components.

    Abstract: Improved utilization of connections that can be either available or blocked is provided by associating an atemporal connection state with each connection. If a connection is available, messages are transmitted on the connection normally. If a connection is blocked, the atemporal connection state is updated to reflect the changes that were made but not transmitted. In this manner, a record is kept that allows correct transmission of the information when the connection comes back up. More specifically, after a connection status changes from blocked to available, recovery messages are automatically generated from the atemporal connection state and transmitted on the connection.

At a later time, a coordinated logical re-introduction of the device to the systems or computers from which the device was logically removed can be performed. This can be accomplished via a virtualization system that may include a device function driver (DFD), a device virtualization bus driver (DVBD), and a device management service (DMS).

  • Patent number: 9396150
    Abstract: A system and method are disclosed to prevent a reduction in the number of I/O devices which can be connected when building a PCIe topology by connecting I/O devices to a computer via a PCIe switch. A switch with which a computer and I/O devices are connected includes: a first PCI-PCI bridge which is positioned on the computer side; a second PCI-PCI bridge which is positioned on the I/O device side; trapper units which trap packet data which is inputted into the switch; a packet routing unit which transfers packet data to the I/O devices; and a management processor which is connected to the trapper units and provides the computer a virtual PCI-PCI bridge and a virtual link by execution of a program. The trapper units adjudicate the destination of the packet data which is transferred from the computer.

  • Patent number: 9372774
    Abstract: A redundant computing architecture includes a first control unit, a second control unit, and a switch. The first control unit is configured to provide a first control signal in response to a sensory input and is further configured to provide a health status indicator that is indicative of a fault condition within the first control unit. Additionally, the second control unit is configured to provide a second control signal in response to the sensory input. Each of the first and second control signals is respectively operative to control an actuator. The switch is configured to: receive the health status indicator, the first control signal, and second control signal; provide the first control signal to the actuator if this health status indicator does not indicate a fault: and provide the second control signal to the actuator if this health status indicator does indicate a fault.

  • Patent number: 9336028
    Abstract: Systems and methods are disclosed to enable switching of graphics processing unit (GPU) resources based on different factors. Embodiments include a virtual graphics driver as an interface between GPU drivers and the applications or graphics framework executing on an electronic device. The virtual graphics driver may switch GPU resources from a first GPU to a second GPU by routing function calls to the first GPU or the second GPU. The switching of GPU resources may be based on power management, system events such as hot-plug events, load management, user requests, any other factor, or any combination thereof. In some embodiments, a virtual frame buffer driver is provided that interfaces with the frame buffer of the GPU and provides a virtual view of the frame buffer to manage additional system application programming interfaces (APIs) during the switch.

  • Patent number: 9329653
    Abstract: A method for replacing or repairing a non hot swappable component according to one embodiment includes supplying power to a first motherboard partition, a first storage partition, a second motherboard partition, and a second storage partition concurrently. The first storage partition is accessed and utilized with the second motherboard partition. The power to the first motherboard partition s selectively severed, and a non hot swappable component that has failed is removed from the first motherboard partition and replaced with a functioning component. Power is restored to the first motherboard partition.

  • Patent number: 9320160
    Abstract: A multicage small form-factor pluggable (SFP) unit comprises a front portion, and a plurality of cages mounted to a rearward side of the front portion. An actuator may emerge from the front portion, for disengaging the plurality of cages from a chassis upon upward movement of the actuator. One or more external connectors may be mounted to a front panel of the front portion. One or more rear connectors may be mounted to a back panel of at least one of the cages, for connecting to a backplane. At least one of the cages may comprise one or more processing modules. Various combinations of internal connections may be implemented between the external connectors if any, the rear connectors if any, and the processing modules if any. The multicage SFP unit may for example comprise two, three or four cages arranged in a horizontal row.

  • Patent number: 9311266
    Abstract: A mapping and correspondence may be established between a virtual topology and a physical topology of a PCIe subsystem, and a host may be presented with the virtual topology but not the actual physical topology. A semi transparent bridge may couple an upstream host to the PCIe subsystem that includes intermediary bridges and respective PCIe endpoints coupled downstream from the intermediary bridges. The intermediary bridges may be hidden from the host, while the respective PCIe endpoints may be visible to the host. A configuration block may provide to the upstream host, during a setup mode, first memory allocation information corresponding to the intermediary switches, responsive to the upstream host expecting second memory allocation information corresponding to the respective PCIe endpoints. The configuration block may then provide to the upstream host, during a runtime mode, the second memory allocation information, responsive to the upstream host expecting the second memory allocation information.

  • Patent number: 9304791
    Abstract: The present invention relates to dispositioning state changes for applications. An application can be executed with different behaviors depending on the resources available to the application. The application can be executed with one behavior based on the availability of a specified resource and can be executed with another different behavior when a change in availability of the specified resource is detected. A configuration can be applied to an application based on a fist defined state for the application. Applying the configuration causes the application to execute with a first behavior. A change in available resources defines a second state for the application. The change in available resources is dispositioned (e.g., stored or discarded) in accordance with a policy based on a determine context for the second state.
