## Supported Configurations

The following instance and volume configurations are supported for utilization reporting (Sensor and Autoscaler) and for autoscaling (AutoScaler).

### Additional Considerations

{% hint style="warning" %}
When installing AutoScaler on Kubernetes, all of the nodes in the cluster must be supported (Nitro hypervisor and size ≥ `xlarge` ). If your cluster contains mixed instance type, let us know.
{% endhint %}

{% hint style="warning" %}
On EC2 instances, autoscaling will not be enabled for volumes that do not follow the [best practice](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-using-volumes.html) of using the filesystem UUID in the relevant `/etc/fstab` entry. Using the device path (e.g., `/dev/sdf` or `/dev/nvme1n1`) can result in failure to mount an autoscaling volume after reboot or mounting the volume to the wrong mountpoint, and is not supported.
{% endhint %}

[^1]: All new instance types use the Nitro hypervisor. See [AWS documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#instance-hypervisor-type) for breakdown by instance type
