VM Resource and Availability Service

Home / VMware / VM Resource and Availability Service

The engineers at VMware have released a cool tool that 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.

To Get started :-

  1. Open hasimulator.vmware.com to access the web service.
  2. Click on “Simulate Now” to accept the EULA terms, upload the DRM dump file and start the simulation process.
  3. Click on the help icon (at the top right corner) for a detailed description on how to use this service.

Enjoy!
