7. Delivering Continuously Available Applications
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 of sufficient length to minimize possibility of packet reordering
Flows can be moved to other team members on flowlet boundaries to rebalance traffic
Dynamic LBFO maximizes resource utilization in teamed NICs by balancing loads across all NIC team members
Ideal when there are fewer VMs per team
