VMware vSphere 6 - High Availability Clusters

Learn to deliver very high VM availability through VMware High Availability (HA) Clusters | taught by Larry Karnis

Course description

Virtualization creates unique challenges when it comes to delivering very high Virtual Machine availability. When an ESXi host fails, all of the Virtual Machines on that host also fail. Furthermore, any problem in your shared storage network or server can lead to storage loss which will also cause Virtual Machines to fail. VMware High Availability Clusters are groups of two or more ESXi 6 hosts that cooperate to deliver very high Virtual Machine availability. They do this by identifying ESXi host or Storage failures and then re-assigning failed VMs to surviving ESXi hosts. In this way VMs will experience only a short outage even if you experience a complete server failure.

In this class you will learn:

  • The features and capabilities of High Availability (HA) clusters
  • The hardware, operating system, networking and shared storage requirements of HA clusters
  • How to create an HA cluster
  • How to add ESXi hosts to your cluster
  • How to understand, configure and use HA cluster policies like Host Monitoring, VM Monitoring, All Paths Down, Permanent Device Loss and Admission Control
  • How Host failures are detected including Host network isolation and complete Host failures
  • How to configure the HA Restart Priority settings to ensure your critical VMs are placed and restarted first
  • How to review and edit your HA cluster settings
  • To avoid configurations and situations that put your HA cluster at risk
  • Best practices for High Availability clusters

By the end of this course you will understand HA clusters and their policies, you will know how to design your management network for continued HA functionality, how HA detects host and storage issues and how you can employ vSphere HA clusters to deliver high VM availability.

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.

About Me

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.
