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 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 for instructions.
