In a vSphere environment, physical network resources are shared across multiple virtual machines and services. The ability to ensure that sufficient capacity is available across shared resources thus becomes important. If a single virtual machine or a VMkernel network service, such as vMotion or Fault Tolerance, saturates the available network capacity, other virtual machines and services, including host management services, may be adversely impacted.
Identify the traffic shaping and network resource controls available on the virtual network switches.
Determine the network resources required for different traffic types: management, IP storage, vMotion, and virtual machine traffic.
Design traffic shaping or Network I/O Control policies to guarantee or limit network resources for the network traffic types based on design requirements.
