    1111== Cluster Groups ==

    13 In SCDB, machine profiles are grouped in ''clusters''. SCDB clusters are arbitrary group of machines and have nothing to do with a batch cluster or an underlying cluster technology. All the nodes in a cluster will share in particular the same ''include path'' for templates (that means that templates will be looked at the same locations for all nodes in the cluster), except for OS templates (see section on selecting OS version in OS templates documentation).

    1515Since SCDB [milestone:SCDB-2.3.1 2.3.1], it is possible to define cluster groups. Previously all clusters where corresponding to one directory under `clusters` directory. It is now possible to group them into several cluster groups matching your site organization (groups can match a geographical location, an organisational group... SCDB makes no assumption about this). Every group will correspond to one directory in `clusters` directory and every cluster will have one directory in the group it belongs to.
