vSphere Fault Tolerance for virtual machines
Fault-tolerant virtual machines are always anticipated in a highly available environment. Fault Tolerance not only ensures high availability but also promises stability for your virtual machines by minimizing the impact of failover rates. The more you use fault tolerance, the more you will need the skills in Fault Tolerance troubleshooting. In the upcoming section, we will discuss some of the most common problems relevant to a virtual machine's fault tolerance and how to troubleshoot them.
Before we get into troubleshooting, here's a list of some best practices for VMware Fault Tolerance configuration to avoid having problems:
Your cluster should consist of at least three vSphere hosts to provide Fault Tolerance to your infrastructure.
Always use a dedicated NAS/SAN for your storage environment equipped with at least 1 Gbit NICs.
Do not use more than 16 virtual disks.
Your resource pool should have more memory than allocated to fault-tolerant virtual...
