# Host Failure Modelling (Hyper-V)

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

- The **Summary** section provides an overview of the current state of your infrastructure (the total number of clusters, hosts, datastores, and VMs) and shows recommendations on resource allocation.
- The **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.
- The **Details** table provides details on CPU and memory current and predicted utilization for all clusters included in the report.
- The **Recommendations** section provides recommendations for the resources whose utilization thresholds will be breached.

::: 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.

## Report Parameters

You can specify the following report parameters:

- **Infrastructure objects**: defines a virtual infrastructure level and its sub-components to analyze in the report.
- **Number of failed hosts**: defines the number of random hosts for which you want to simulate a failure.
- **Failed hosts**: defines a list of hosts for which you want to simulate a failure.
- **Business View migration scope**: filters report scope objects that belong to the selected Business View groups.
- **CPU utilization threshold (%)**: defines the CPU usage threshold as a percentage of total cluster CPU resources.
- **Memory utilization threshold (%)**: defines the used memory threshold as a percentage of total cluster memory resources.

## Use Case

The report provides recommendations on appropriate resource allocation, which can help prevent possible CPU and memory resource shortfalls in future and maintain the optimal performance of your infrastructure.
