DataClass Management

Files controlled by FileServ are segregated into DataClass groups. A DataClass group contains a unique set of parameters that govern the migration behavior of the directories that are associated with the class.

The figure below depicts directory-to-DataClass relationships:

SPECIAL

special/

dir/ … dirn/	file1 … filen

The test/proc/special directory is the only association directory point for the DataClass SPECIAL. All files beneath /test/proc/special are managed together.

The DataClass PRODUCT contains all files under the /prod/dev and /prod/doc directories, but none under the /prod/misc directory. This shows that some directories at a certain level may not be related to a DataClass group.

prod/

other/ test/

PRODUCT

misc/ dev/ doc/

TESTERS

private/build/

public/

dir/ … dirn/ file1 … filen	dir/ … dirn/

Operaitng Tasks

All files under /test/build and /test/proc/public belong to DataClass TESTERS. This illustrates that the assignment of migration directories to a DataClass group is not restricted to a certain level in the tree structure. Thus, migration directories from different file systems can be associated with the same DataClass identifier.
