Figure 39 Legacy Style of Packaging
Figure 40 illustrates the consolidated modular CFS packages; all the disk group and mount point
packages used by Application 1 are consolidated into a single modular package. Similarly, the
disk group and mount point packages used by Application 2 are consolidated into a single modular
package. The disk group, cvm_dg3, is merged with the snapshot package to enable consolidation
of storage within the same package. The checkpoint package is configured into a single package
as it cannot have disk groups, mount points, or snapshots configured within the same package.
This consolidation has reduced the number of packages to six in the modular style of packaging
as compared with the legacy style of packaging where the number of packages is nine. It is
recommended to consolidate the disk group and mount point packages into modular packages
for Application 1 and Application 2 separately, and not to share the modular packages between
the applications unless the applications are interdependent.
