Virtual RSS (vRSS) vRSS provides near line rate to a VM on existing hardware, making it possible to virtualize traditionally network intensive physical workloads Maximizes resource utilization by spreading VM traffic across multiple host and guest processors Dynamic VMQ (DVMQ) Standard VMQ spreads VMs to different cores statically DVMQ adds or removes cores as the processing requirements change Results in better processor use for adaptive network workloads Dynamic NIC teaming TCP streams or "flows” are generally not continuous Groups of packets sent between flows are called “flowlets” Dynamic load balancing detects breaks in a flow Flows can be moved to other team members on flowlet boundaries to rebalance traffic Dynamic LBFO maximizes utilization of teamed NICs

RDMA Higher throughput with low latency through offload Take advantage of high-speed networks such as InfiniBand and iWARP Remote storage at the speed of direct storage Compatible with SMB Multichannel for load balancing and failover SR-IOV VM traffic bypasses virtual switch and performs I/O directly to NIC Ideal for high I/O workloads that do not require port policies, QoS, or network virtualization enforced at the end host virtual switch Reduce CPU overhead, network latency, and increase throughput

How network virtualization works Overlays multiple virtual networks onshared physical network Uses industry standard General RoutingEncapsulation (NVGRE) protocol Problems solved Creates VM mobility across datacenter, hoster cloud or Azure without network constraints Provides ability to import customer IP addresses and network topology Helps remove VLAN constraints Helps eliminate hierarchical IP address assignment for virtual machines
