Planning Virtual Machine Networks

Plan network resources to determine how you will allocate available virtual networks to the virtual machines (VMs) on your everRun system.

When you install the everRun software, it binds pairs of physical network ports across the two physical machines (PMs) to form redundant virtual networks. When you create or reprovision VMs on your everRun system, you connect the VMs to these virtual networks instead of the physical network ports.

When connecting VMs to virtual networks, consider the following information and restrictions:

• You can connect one VM to multiple virtual networks, and you can connect multiple VMs to the same virtual network.
• The everRun software allows unlimited over-provisioning of network resources; therefore, be sure to profile a VM’s network bandwidth/response time requirements when allocating virtual networks.
• When multiple VMs share the same virtual network, available network bandwidth is shared equally between the VMs. Unlike vCPU capacity, there is no way to proportionately allocate bandwidth resources. Therefore, high use of network resources by one VM can reduce the performance of all VMs on that network. If a VM has a large bandwidth requirement, consider connecting a dedicated virtual network to that VM.
