In this two-day course, you will focus on learning the tools and skills necessary to troubleshoot VMware vSAN 6.6 implementations.You will gain practical experience with vSAN troubleshooting concepts through the completion of instructor-led activities and hands-on challenge lab exercises.

By the end of the course, you should be able to meet the following objectives:

• Describe the software components
• Diagram how the components relate to each other
• Describe vSAN object placement
• Explain the differences between object states
• Explain how storage policies affect object states
• Predict how specific failures affect object states

Storage and virtual infrastructure administrators who want to be able to perform initial troubleshooting on their software-defined storage with vSAN

This course requires completion of one of the following prerequisites:

• Understanding of concepts presented in the VMware vSphere: Install, Configure, Manage [V6.5] course
• Completion of the VMware vSAN: Deploy and Manage [V6.6] course or equivalent experience with vSAN
• Experience working with Linux command-line interfaces The course presumes that a student can perform the following tasks with no assistance or guidance before enrolling:
• Use VMware vSphere® Web Client for common operations
• Create and manage VMware vCenter Server objects, such as data centers, clusters, hosts, and virtual machines
• Create and modify a standard switch
• Modify a distributed switch
• Create a VMware vSphere® VMFS datastore
• Use a wizard or a template to create a virtual machine
• Migrate a virtual machine with VMware vSphere vMotion and VMware vSphere Storage vMotion If you cannot complete all of these tasks, VMware recommends that you complete the VMware vSphere: Install, Configure, Manage [V6.x] and VMware vSAN: Deploy and Manage [v6.x] courses before enrolling in VMware vSAN: Troubleshooting.
