2.1.3 Cluster Resources
Cluster resources are grouped into Services and Applications groups. Several resources
grouped together can be organized via dependencies which ensures that a single resource
cannot be brought online (to a functional status) if any resource higher in the hierarchy is
itself not online--whether because it has been turned off or is dysfunctional.
In a typical 3PAR GeoCluster for Windows configuration, three following resources can be
found:

The 3PAR GeoCluster for Windows resource, on which the disk resources depend.

The disk storage resources, which correspond to Virtual Volumes located on InServ
storage arrays. They depend on the 3PAR GeoCluster for Windows resource and any
application resource depends on a disk storage resource.

The application resources, which are hosted on the disk resources on which they
depend.
Figure 2-2: Example of resources dependencies
CAUTION: Each 3PAR GeoCluster for Windows resource corresponds to a
single Remote Copy group. Though a 3PAR GeoCluster for Windows
resource may manage several disk resources, all these disk resources have
to be located on VVs in the same Remote Copy group (see diagram below).
