Role DM: Distributed Cache Cluster Data Server, Standalone Instance, Shard Master Data Server
If multiple nodes of role AM and a DM node (nonmirrored or mirrored) are specified, they are deployed as an InterSystems IRIS distributed cache cluster, with the former serving as application servers and the latter as an data server.
A node of role DM (nonmirrored or mirrored) deployed by itself becomes a standalone InterSystems IRIS instance.
If a DM node (mirrored or nonmirrored), DS nodes (mirrored or nonmirrored), and (optionally) QS nodes are specified, they are deployed as a namespace-levelOpens in a new tab sharded cluster.
