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.

Take-over of network frame handling in a computing environment

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).

Physical port sharing in a link aggregation group

An integrated hybrid system is provided. The hybrid system includes compute components of different types and architectures that are integrated and managed by a single point of control to provide federation and the presentation of the compute components as a single logical computing platform.

Management of a data network of a computing environment

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.

Data isolation in shared resource environments

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.

Virtual network configuration and management

Automatically converting a synchronous data transfer to an asynchronous data transfer. Data to be transferred from a sender to a receiver is initiated using a synchronous data transfer protocol. Responsive to a determination that the data is to be sent asynchronously, the data transfer is automatically converted from the synchronous data transfer to the asynchronous data transfer.

Facilitating communication between isolated memory spaces of a communications environment

A method of operating a computer system comprising a bridge port between a hardware local area network (LAN) and a virtual switch includes providing a first hash table by the hardware LAN to the virtual switch via the bridge port, wherein the first hash table comprises addresses of a first plurality of VMs that comprise the hardware LAN, wherein the first plurality of VMs communicate with the hardware LAN via respective hardware network interface cards (NICs); and updating a second hash table in the virtual switch to include the addresses of the first hash table, wherein the second hash table further comprises addresses of a second plurality of VMs of the virtual switch, wherein the second plurality of VMs communicate with the virtual switch via respective virtual NICs.

Bridge port between hardware LAN and virtual switch

A method for communicating from a first virtual machine, defined by a virtual machine operating system, to an external device via a local area network (LAN). The virtual machine operating system also defines other virtual machines and a base portion common to all of the virtual machines. The first virtual machine writes an IP datagram to an output buffer allocated to the first virtual machine. The IP datagram comprises data and a destination IP address associated with the external device. The program functions in the base portion read the IP datagram from the output buffer to determine the destination IP address and then copy the IP datagram from the output buffer into storage allocated to the common base portion whereby the IP datagram passes from the first virtual machine into the common base portion storage without passing through any other virtual machines. Then, the program functions request a tangible adapter card for the network to send the IP datagram to the IP destination address.

Virtual machine connection to a tangible network

A system and method of managing networks and, more particularly, to a system and method for interfacing with virtual networking devices using SNMP (Simple Network Management Protocol). A system comprises a configuration statement configured to provide an identity to a virtual device. An SNMP subagent is configured to interface between an SNMP agent and a control program of the virtual device. The SNMP subagent acquires information extracted by the control program for the identified virtual device and provides the acquired information to the SNMP agent to be returned to the SNMP client.
