  • Patent number: 10698845
    Abstract: Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.
    Type: Grant

  • Patent number: 9565095
    Abstract: A first component of a computing environment receives, from a physical network adapter of the computing environment, a request that the first component take over processing of network frames directed to network frame address(es) associated with a second component of the computing environment. The first component register the network frame address(es) for processing of network frames directed to the network frame address(es). Based on the first component receiving from the physical network adapter a network frame directed to a network frame address of the network frame address(es) associated with the second component, the first component processes the received network frame, in which the network frame is provided to the second component via an inter-component link between the first component and the second component.

  • Patent number: 9313139
    Abstract: Virtual switches are established in a host system of a computing environment. Each virtual switch of the virtual switches includes a respective virtual switch port grouped within a shared port group of virtual switch ports. The virtual switch ports of the shared port group are in communication with a common physical network adapter of the host system. The virtual switch ports of the shared port group share a single physical port of the physical network adapter as part of a common physical link aggregation group (LAG).

  • Patent number: 9135451
    Abstract: A data connection of a shared resource is placed in isolation mode to remove its ability to communicate with other data connections of the shared resource. This ability to isolate the data connection is dynamic in that it can be turned on/off at any time. This provides increased data security for the entities using the data connection.

  • Patent number: 9106529
    Abstract: A Hardware Management Console (HMC) configures virtual networks. The HMC extends Internal Queued Direct I/O to an intra-ensemble data network (IEDN) within a cluster of virtual servers to define a single channel path identifier, and to define a channel parameter. The HMC defines at least one virtual network. The HMC defines a bridge port within each CPC that supports at least one of the virtual servers. The HMC defines a network interface for each virtual server within each cluster. The HMC grants access to a corresponding virtual network for each virtual server.
