Chapter 7. The vSphere Compute Design

In this chapter, we will cover the following topics:

  • Calculating CPU resource requirements
  • Calculating memory resource requirements
  • Scaling up or scaling out
  • Determining the vCPU-to-core ratio
  • Clustering compute resources
  • Reserving HA resources to support failover
  • Using Distributed Resource Scheduling to balance cluster resources
  • Ensuring cluster vMotion compatibility


This chapter covers logical compute design. Compute refers to the processor and memory resources required to support the virtual machines running in the vSphere environment. Calculating the required CPU and memory resources is an important part of the design process and ensures that the environment will be able to support the virtual machine ...
