# Determining Number of Collectors Required

To estimate the number of Collectors required for your infrastructure, it is highly recommended that you use the Veeam MP for VMware Sizing Calculator available as a part of the Veeam MP for System Center Resource Kit included in the Veeam MP ISO image. For more information on the Veeam MP for VMware Sizing Calculator, see the [Veeam MP for Microsoft System Center Resource Kit Guide](https://helpcenter.veeam.com/docs/mp/resource_kit/introduction.html).

## Additional HA Considerations

To provide failover capability, in addition to the recommendation generated by the Sizing Calculator, you will need:

- One additional unloaded inactive Collector that acts as a warm standby server

  -OR-

- Sufficient headroom for the existing Collectors to accumulate monitoring jobs of any failed Collector
