Refer the following steps to determine bandwidth requirements.
- Calculate the total amount of bandwidth required to support virtual machine network traffic using the following formula:
Total Number or Virtual Machines x Bandwidth per Virtual Machine (Mbps) = Total Bandwidth Requirement (Mbps)
- Calculate the amount of bandwidth required per host. This is dependent on the maximum number of virtual machines that can be run on a single host.
- Determine the network requirements for other vSphere services and features, such as vMotion, iSCSI, NFS, and Fault Tolerance.
- Select the type and number of network adapters to provide the network connectivity that's required to support the design requirements.
