# Adding a Datacenter

You can add a new datacenter (region) to an existing ScyllaDB cluster to scale
out the cluster and provide higher availability (HA).

Choose **Action> Add Data Center** in your cluster’s view to open a request
to add a new datacenter. You’ll need to specify the number of nodes you want
to add in that datacenter. The number of nodes you can add equals or is
a multiple of the Replication Factor set for your cluster (3, 4, or 5).
The cluster status will be verified before provisioning to ensure stability
and performance.

#### NOTE
* The *Add Data Center* option is only available for private clusters.
* Adding a datacenter might take a significant amount of time, between
  a few hours and a full day, depending on your cluster.
* If [Vector Search](https://cloud.docs.scylladb.com/stable/vector-search/index.md) is enabled on your
  cluster, Vector Search nodes are not automatically added to the new
  datacenter. You must deploy Vector Search nodes separately after the
  datacenter is created. See
  [Enabling Vector Search on an Existing Cluster](https://cloud.docs.scylladb.com/stable/vector-search/vector-search-clusters.md#vs-enable-existing)
  for instructions.
