Host Failure Modelling

This report allows you both to simulate a failure of one or more hosts, and forecast CPU and memory usage for Hyper-V clusters.

  • Summary section provides an overview of the current state of your infrastructure (the total number of clusters, hosts, volumes, and VMs) and shows recommendations on resource allocation.
  • Modelling Results charts display the amount of CPU and memory resources left and lost in case of a host failure. The VMs Migration Count chart shows the number of VMs that will need to be relocated to another host (VMs to Migrate) and the number of VMs that will operate as usual (Unaffected VMs) in case of a host failure.
  • Details table provides details on CPU and memory current and predicted utilization for all clusters included in the report.
  • Recommendations section provides recommendations for the resource(s) whose utilization threshold(s) will be breached.

Host Failure Modelling Tip:

  • Click a cluster name in the Details table to drill down to details on current and predicted resource usage for the cluster.
  • Click a number in the Affected VMs column of the Details table to drill down to details for the VM that needs to be migrated.
