vSphere provides several different methods to help you manage your network resources. 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. Jumbo FramesJumbo frames let ESXi hosts send larger frames out onto the physical network. The network must support jumbo frames end-to-end that includes physical network adapters, physical switches, and storage devices. TCP Segmentation OffloadUse TCP Segmentation Offload (TSO) in VMkernel network adapters and virtual machines to improve the network performance in workloads that have severe latency requirements. Large Receive OffloadUse Large Receive Offload (LRO) to reduce the CPU overhead for processing packets that arrive from the network at a high rate. NetQueue and Networking PerformanceNetQueue takes advantage of the ability of some network adapters to deliver network traffic to the system in multiple receive queues that can be processed separately, allowing processing to be scaled to multiple CPUs, improving receive-side networking performance.
