Because vSAN has an extensive HCL, customers can opt multiple server densities.

Note: vSAN Ready Nodes are mostly based on standard 2U rack server configurations.

Denser nodes provide a smaller datacenter footprint where space is a concern. However, keep in mind that the footprint for other datacenter resources such as power and heat and cooling is not necessarily reduced in the same way and that the concentration of nodes can potentially pose other challenges.
