 By default, the system node pool is named `nodepool1`. If you want to enable Azure Container Storage on other node pools, see [Install Azure Container Storage on specific node pools](container-storage-aks-quickstart.md#install-azure-container-storage-on-specific-node-pools). If you want to specify additional storage pool parameters with this command, see [this table](container-storage-storage-pool-parameters.md).

+\*If there are any existing node pools with the `acstor.azure.com/io-engine:acstor` label, Azure Container Storage will install the data plane components by default. Otherwise, users have the option to pass the preferred nodepool to `acstor` through Azure CLI. If the cluster only has the system nodepool, it will be labeled and used for Azure Container Storage by default. It is important to note that only data plane components will be restricted to the labeled nodepool. The control plane components of Azure Container Storage are not limited to the labeled nodes and may be installed on the system node pool as well.
