Effectively managing and assigning ESXi 6 host physical CPU and memory resources is critical to meeting your service obligations and scaling up your vSphere 6 environment. In this chapter we will look at the capabilities and mechanisms present in ESXi 6 and in Distributed Load Scheduling clusters that let you delegate host pCPU and Memory resources in bulk (Resource Pools) and individually to Virtual Machines. We will see how to resource tune VMs and Resource Pools, how to set minimums and caps on resources and how to prioritize resource scheduling based on shares.
In this class you will learn:
- About Reservatsions (guaranteed resource assignments), Limits (resource caps) and Shares
- The default rules for resource delegations to Virtual Machines and Resource Pools
- How resource assignments apply to VMs including the default assignments and how to customize resource assignments
- The purpose of Expandable Reservations and their Use Cases
- How to create and resource tune Resource Pools - Folders with specific resource delegations / tunes
- How Shares can be used to set the relative scheduling importance of VMs and Resource Pools so you can ensure predictable resource delegations even during periods of high resource stress
- How to review and fine tune resource delegations
Best Practices for resource tuning
By the end of this course, you will be able to size and resource tune Virtual Machines and Resource Pools correctly. You will understand how ESXi delegates resources and will be able to delegate resources to ensure your most critical VMs get the resources they need to run well, even under periods of high resource stress.
Get VMware vSphere & View Training... for less!
Q: What do you do if you need to learn VMware but can't afford the $4,000 - $6,000 charged for authorized VMware vSphere training?
A: Enroll in my equivalent VMware vSphere 6.5 and Horizon View video-on-demand training... for less.
Many name is Larry Karnis - and I create courses that will help you start your career as a VMware vSphere 6.5 administrator, and help you build you knowledge and skill in vSphere 6.5 advanced features and capabilities.
With Video-On-Demand training, I can provide more insight and detail, without the time constraints that a normal instructor led training class would impose. My goals are to:
- Give you a better training experience than classroom training
- Help you learn more than you can learn in a 5 day class
- Give you the opportunity to learn at your own pace
- Provide you to supporting books and hands-on lab rentals
At price points that you (or your boss) will appreciate.

I am an Information Technology consultant / trainer with over 30 years of experience in system administration, networking, security, infrastructure and security.
I worked for 10 years as a UNIX programmer / consultant before moving to Linux in 1995. I started working with VMware products in 2001 and decided to focus exclusively on VMware in 2004. I earned my first VMware Certified Professional (VCP) designation on ESX 2.0 in 2004 (VCP #: 993). I have also earned VCP in ESX 3, and in vSphere 4 and 5.
My VMware Work Experience
- I have been providing VMware consulting and training for more than 14 years. I have lead literally hundreds of classes and taught thousands of people how to use VMware. I teach both introductory and advanced VMware classes.
- I worked for VMware as a senior contract VMware Certified Instructor (VCI) and consultant for almost 5 years. One of my regular duties was to help mentor new VCI's - helping them prepare for and successfully deliver vSphere classes.
- After leaving VMware, I launched my own training business focused on VMware virtualization in 2008. In 2013, VMware called me back to help them ramp up support services for the upcoming vSphere 5.1 product launch.
- Prior to VMware, I worked as a contract consultant / trainer for RedHat (I hold RHCE, RHCI and RHCX), Global Knowledge, Learning Tree and many other training and consulting companies.
I hold a Bachelor of Science degree (majoring in Computer Science with a minor in Math) from the University of Toronto, Canada.
I also hold numerous industry certifications including VMware Certified Professional on VMware Infrastructure 2 & 3 and vSphere 4 & 5 (ret.), VMware Certified Instructor (ret.), RedHat Certified Engineer (RHCE), RedHat Certified Instructor (RHCI) and RedHat Certified Examiner (RHCX) as well as certifications from LPI, HP, SCO and others.
I hope to see you in one of my VMware classes very soon... If you have questions, please contact me directly.
