 ## Example of a simple cluster
 
 The Keeper ensemble size must be odd because it requires a majority (50% + 1 nodes) to form a quorum. A 2-node Keeper setup will lose quorum after a single node failure, so the recommended number of Keeper replicas is 3.
 
-On `hostname1` and `hostname2` below, ClickHouse can use the embedded Keeper cluster from `<keeper_server>`, so a separate client-side `<keeper>` section is not required. If your ClickHouse servers connect to an external Keeper or ZooKeeper ensemble, see [ClickHouse config for Keeper]({{< ref "clickhouse-keeper-clickhouse-config" >}}).
