Summary
In this chapter, you covered an overview and learned about the design of cluster expansion in the VxRail 7.x system, including the scale-out and scale-in rules for each model for a VxRail node. Compared to the traditional architecture of server and storage, you can see that VxRail cluster expansion is very easy and flexible.
In the next chapter, you will learn about the design of the vSAN two-node cluster on VxRail and the best practices of this solution.
