摘要： A mechanism is provided for providing resource affinity for multi-queue network adapters via dynamic reconfiguration. A device driver allocates an initial queue pair within a memory. The device driver determines whether workload of the data processing system has risen above a predetermined high threshold. Responsive to the workload rising above the predetermined high threshold, the device driver allocates and initializes an additional queue pair in the memory. The device driver programs a receive side scaling (RSS) mechanism in a network adapter to allow for dynamic insertion of an additional processing engine associated with the additional queue pair. The device driver enables transmit tuple hashing to the additional queue pair.

摘要： An information handling device receives a packet and determines a packet destination for the packet. In turn, the information handling device either aggregates the packet in response to determining that the packet destination is a local destination, or forwards the packet in response to determining that the packet destination is a non-local destination.

摘要： In link aggregation configurations, a data packet may be copied into a buffer space of a first NIC. Load balancing techniques may determine that the packet should be transmitted by a second NIC. The packet exists in memory that the second NIC cannot access. The data packet is copied into memory accessible to the second NIC or the memory location of the packet is registered with the NIC. A copy penalty is incurred if a packet is copied from a first buffer space to a second buffer space. A registration penalty is incurred if the location within the first buffer space is registered with the second NIC. Functionality can be implemented within a link aggregation configuration to register buffer space shared among interconnected NICs. Sharing of buffer space between interconnected NICs allows any one of the NICs to access data within the shared buffer space without incurring a penalty.
摘要翻译：在链路聚合配置中，可以将数据分组复制到第一NIC的缓冲空间中。负载均衡技术可以确定分组应该由第二NIC发送。数据包存在于第二个NIC无法访问的内存中。将数据包复制到第二个NIC可访问的存储器中，或者将该数据包的存储位置注册到NIC。如果将数据包从第一个缓冲区复制到第二个缓冲区，则会产生复制损失。如果第一个缓冲空间内的位置与第二个NIC进行了注册，就会产生注册损失。可以在链路聚合配置中实现功能，以注册在互连NIC之间共享的缓冲区空间。在互连NIC之间共享缓冲区空间允许任何一个NIC访问共享缓冲区空间内的数据，而不会造成惩罚。

摘要： The method determines whether a particular virtual adapter of a virtual network IHS may perform enhanced packet communication transfer of larger sizes than those of physical network IHSs. The method registers each virtual adapter maximum receive unit (MRU) value in an MRU attribute table within a hypervisor virtual switch. The hypervisor virtual switch provides communication pathways for packet transfers between virtual network IHS virtual adapters and also between physical adapters. The method determines if a sending virtual adapter is sending a packet to a receiving virtual adapter that is local or a remote virtual trunk adapter. The method determines if the receiving virtual adapter exhibits a registered MRU value. If the receiving virtual adapter exhibits a registered MRU value, the method provides for larger sizes of packet transfers for those particular packets.

摘要： A method for selective link aggregation in a virtualized data processing environment is provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to obtain buffers in a multiprocessor system. A software component receives a call from an I/O device driver for a buffer, the call including at least one parameter, and walks a bucket data structure to a current bucket. The software component then determines whether the current bucket is free, and obtains a buffer list contained with the current bucket. Responsive to a determination that the current bucket is free, the software component determines whether sufficient buffers are obtained based on the parameter. Upon determining there are sufficient buffers obtained, the software component provides the current bucket and a second bucket as a single buffer list to the I/O device driver.
