How it works...
The physical network infrastructure must be capable of supporting the total throughput requirement of the environment. The total throughput requirement is calculated by multiplying the number of virtual machines by the throughput that's required by a single virtual machine:
100 Virtual Machines x 10 Mbps = 1,000 Mbps Total
The throughput that's required for a single host is calculated by multiplying the number of virtual machines that will run on a host by the throughput that's required by a single virtual machine:
20 Virtual Machines x 10 Mbps = 200 Mbps per Host
Network adapters are generally capable of delivering throughput equal to approximately 80 percent of the adapter speed, for example, 800 Mbps for a 1 Gbps network ...
