Not surprisingly, the power user requires more disk overhead, and has larger

spikes in activity than the office worker. With that in mind, the power user requires

approximately 10.7 IOPS per guest.

Networking requirements

It is important to ensure that the VDI infrastructure has sufficient network

bandwidth to allow for optimum viewing. As Figure 10 shows, RHEV’s remote desktop

protocol SPICE (Simple Protocol for Independent Computing Environments) uses very

little network traffic. Each office user used 1.5 Mbit/second of network traffic in SPICE,

using just over one-tenth of a percent of a single 1Gb network port’s capability.
