Expanding the initial deployment
To properly evaluate the different compute, network, and storage options we've discussed in this chapter, an expanded OpenStack deployment with dedicated roles for different physical systems is required. Separating the compute functions from the control functions allows us to properly test different types of compute hardware. Separating storage functions from compute and control functions allows us to properly test different disk, NAS, or SAN configurations. In this section, we'll split out the roles we deployed in Chapter 1, Introducing OpenStack, to three physical systems. Each of these systems will be assigned a role, called a host group.
