In the last chapter, we took a look at how vSphere utilizes CPU resources and optimizes VM configurations in order to get the best performance. You also learned about the role of NUMA and vNUMA in high-performance setups. In this chapter, you will learn the memory resource essentials and how reclamation mechanisms such as page sharing, swapping, ballooning, and compression play a role in workload performance.
In this chapter, we will dive deep into the following topics:
In vSphere, memory resources are divided into the following categories:
