Data flow affinity for heterogenous virtual machines

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.
