Continuous VM Availability with Fault Tolerance

Guarantee Zero Unplanned Virtual Machine down time with VMware Fault Tolerance | taught by Larry Karnis

Course description

There are some Virtual Machines that are so important that you cannot tolerate any VM down time - regardless of the underlying cause. VMware Fault Tolerance is real time Virtual Machine replication technology that hot replicates the running CPU state, memory state, network state and disk state of a Virtual Machine to a peer ESXi host and datastore. Fault Tolerance protected VMs run in Primary / Secondary mode with the Secondary copy kept up to date with changes in the Primary VM. If the ESXi host running the Primary VM should fail or lose connectivity to SAN storage, Fault Tolerance will switch over to running the Secondary VM instantly, with no loss in VM service. In this way, network peers will continue to receive service.

In this course, you will learn:

  • The features, capabilities and limitations of vSphere Fault Tolerance
  • What's New with Fault Tolerance in vSphere 6.0
  • High Availability cluster requirements that must be met before you can enable Fault Tolerance
  • Virtual Machine configuration requirements for Fault Tolerance support
  • How to perform Compliance Checks to ensure that your servers and VM are ready for Fault Tolerance
  • How to enable Fault Tolerance Protection on a Virtual Machine
  • Design strategies to maximize Fault Tolerance Performance
  • Virtual Machine Scalability limits imposed by VMware Licenses
  • Fault Tolerance operations like Migrate Secondary, etc.
  • Use Cases for Fault Tolerance
  • Fault Tolerance Best Practices

By the end of this course, you will know the limitations and use cases for Fault Tolerance, how to configure clusters and VMs to enable Fault Tolerance, how to protect VMs and how to deliver continuous VM availability regardless of infrastructure issues.

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.

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.
