VMware Certified Instructor Rick Crisci provides an overview of vSphere resource controls—shares, limits, and reservations—and their impact on performance and VSWP file size. Rick explains exactly what happens when virtual machines compete for resources, the role of swap files, and how resource controls help automate allocation.
In chapter 2, Rick shows how to manage performance with resource pools, including child pools. He explains the impact a reservation has on resource pools, and includes a demo on creating and configuring a resource pool. Chapter 3 is an overview of the vFlash architecture for leveraging SSD resources. Watch this chapter to learn how to configure vFlash reservations and to assign a reservation to a VM.
Note: This course maps to the Administer and Manage vSphere 6.x Resources domain of the vSphere Certified Professional 6—Data Center Virtualization (VCP6DCV) exam.

Skill Level Intermediate
- Hello, and welcome to the administer and manage vSphere resources course. My name is Rick Crisci, and I'm your VMware-certified instructor. I teach a wide variety of official VMware courses, and I'm also the primary author for trainertests.com. In this course, I'll explain key concepts about performance within the vSphere environment. I'll explain vFlash, resource pools, and shares, limits, and reservations. We'll also take a deep look at how CPU and memory resources are distributed to virtual machines.
I'll demonstrate many of these tasks in the VMware hands-on lab environment so you can follow along without building a home lab. So let's get started.
