 The {PVE} cluster manager `pvecm` is a tool to create a group of
 physical servers. Such a group is called a *cluster*. We use the

-communication, and such clusters can consist of up to 32 physical nodes
-(probably more, dependent on network latency).
+communication. There's no explicit limit for the number of nodes in a cluster.
+In practice, the actual possible node count may be limited by the host and
+network performance. Currently (2021) there are reports of clusters (using
+high-end enterprise hardware) with over 50 nodes in production.
 
 `pvecm` can be used to create a new cluster, join nodes to a cluster,
 leave the cluster, get status information and do various other cluster
