# Scaling

A cluster scales out by adding storage nodes, and it scales its provisioning limit by growing a storage pool. Both are
online operations, and the data is rebalanced onto the new capacity afterward. Adding the storage nodes themselves is
part of the deployment, described under
[Deploy a Storage Plane](../../installation/install-sp.md).
