vSphere provides several different methods to help you manage your network resources. vSphere Network I/O ControlUse vSphere Network I/O Control to allocate network bandwidth to business-critical applications and to resolve situations where several types of traffic compete for common resources. TCP Segmentation Offload and Jumbo FramesUsing TCP Segmentation Offload (TSO) in a VMkernel network adapter and virtual machines, and jumbo frames on a vSphere distributed switch or vSphere standard switch, improves the network performance in virtual machines and infrastructure workloads. DirectPath I/ODirectPath I/O allows virtual machine access to physical PCI functions on platforms with an I/O Memory Management Unit. Single Root I/O Virtualization (SR-IOV)vSphere 5.1 and later releases support Single Root I/O Virtualization (SR-IOV). You can use SR-IOV for networking of virtual machines that are latency sensitive or require more CPU resources.
