In the High Availability video, Daniel shows you high availability works and it's advantages over traditional server outage restoration methods. He then discusses the methods of server, vm, and application outage detection and the instances where the VM will be restarted.
- [Voiceover] High availability is a business continuity…feature that allows us to automatically restart…a virtual machine on another host in the event of…a host failure, a guest operating system failure,…or an application failure.…Imagine the time that it takes to detect a failure,…recieve an alert of a failure, react to a failure,…and then start the triage and troubleshooting processes.…All of that time is eliminated with high availability.…In this diagram we have four ESXi hosts…within a host cluster.…
If ESXi one fails then all of the virtual machines…on that host fail as well by shutting down…unexpectedly and forcefully.…With high availability enabled…the virtual machines on ESXi one look for…other hosts within the cluster that have available…resources where they could relocate to…and power themselves on.…High availability doesn't just randomly…reboot virtual machines.…There are several criteria that need to occur.…The first criteria is to determine whether…an ESXi host has incurred a true outage…or whether it is simply isolated from the cluster,…
