Today I was checking the VMware flings site and found one very cool fling which I think is worth sharing as it can help you analysing your environment and help you designing in such a way that resources are highly available to you in case of any disaster.

This Fling enables you to perform a what-if analysis for host failures on your infrastructure. You can simulate failure of one or more hosts from a cluster (in vSphere) and identify how many:

  • VMs would be safely restarted on different hosts
  • VMs would fail to be restarted on different hosts
  • VMs would experience performance degradation after restarted on a different host

With this information, you can better plan the placement and configuration of your infrastructure to reduce downtime of your VMs/Services in case of host failures.
