This chapter explores different settings that may improve a virtual machine's resource allocation and performance, if needed. These resource allocation settings affect the amount of resources given to a virtual machine and how virtual machines compete when in contention. These settings include shares, limits, and reservations and can be applied to CPU and memory resources. Shares and limits may also be configured for storage and network resource access, depending on your vSphere licensing tier.
In this chapter, you will learn about:
CPU scheduler
Memory reclamation techniques
Shares, limits, and reservations
Resource pools
Network I/O Control
Storage I/O Control
Disk alignment
Performance tuning
