Abstract: Mechanisms are provided for performing traffic load balancing on ingress traffic directed to a Link Aggregation Group (LAG). The mechanisms monitor a ingress traffic load across a plurality of links of the Link Aggregation Group (LAG). The mechanisms determine if the ingress traffic load across the plurality of links is unbalanced. Moreover, the mechanisms, in response to determining that the ingress traffic load across the plurality of links is unbalanced, send a message to a switch associated with the LAG requesting the switch to modify routing of ingress traffic to the LAG to perform ingress traffic load balancing.

Abstract: According to one aspect of the present disclosure, a method and technique for data flow affinity for heterogeneous virtual machines is disclosed. The method includes: connecting first and second logical partitions to a shared virtual adapter, the first logical partition having a maximum receive unit (MRU) different than a MRU of the second logical partition; and responsive to receiving data by the shared virtual adapter destined for the first or second logical partitions, performing transmission control protocol (TCP) segmentation offload processing of the data by the shared virtual adapter utilizing the MRU of the first logical partition as the transmission unit for data destined for the first logical partition and utilizing the MRU of the second logical partition as the transmission unit for data destined for the second logical partition.

Abstract: According to one aspect of the present disclosure a system and technique for data flow affinity for heterogeneous virtual machines includes a hypervisor operable to manage a virtualized environment comprising first and second logical partitions, the first logical partition having a maximum receive unit (MRU) different than a MRU of the second logical partition. The system also includes a virtual input/output server (VIOS) having a shared virtual adapter connected to the first and second logical partitions. The shared virtual adapter is configured to, responsive to receiving data destined for the first or second logical partitions, perform transmission control protocol (TCP) segmentation offload processing of the data utilizing the MRU of the first logical partition as the transmission unit for data destined for the first logical partition and utilizing the MRU of the second logical partition as the transmission unit for data destined for the second logical partition.

Abstract: Provided are techniques for configuring a primary shared Ethernet adapter (SEA) and a backup SEA into a failover (F/O) protocol; providing a user interface (UI) for enabling a user to request a SEA load sharing protocol; in response to a user request for a SEA load sharing protocol, verifying that criteria for load sharing are satisfied; setting, by the UI a load sharing mode, comprising: requesting, by the backup SEA to the primary SEA, implementation of the SEA load sharing protocol; responsive to the requesting by the backup SEA, the primary SEA transmit an acknowledgment to the backup SEA and transitions into a sharing state; and responsive to the acknowledgment from the primary SEA, the backup SEA transitions to the sharing state.

Abstract: Embodiments of the present invention provide methods, systems, and computer program products that enable secure network communications with logical partitions. A gateway between a physical network adapter and at least one virtual network trunk adapter receives a packet. The gateway tags the packet with an indication of an origin of the packet. The gateway delivers the tagged packet to an intrusion prevention system for intrusion analysis. When the gateway receives the tagged packet from the intrusion prevention system, the gateway forwards the tagged packet according to the indication of origin of the tagged packet.

Abstract: A method, apparatus, and computer instructions for recovering terminated partitions in a logical partitioned data processing system. A termination of a partition in a set of partitions associated with a host bridge in the logical partitioned data processing system is detected. The state of other partitions within the set of partitions is checked in response to detecting the termination. A recovery process is initiated if all partitions in the set of partitions have terminated. Input/output slots associated with the host bridge are reset to a normal state if the recovery process is successful. The set of partitions is rebooted after resetting the input/output slots associated with the host bridge without rebooting the logical partitioned data processing system.
