The global namespace is organized into filesets. Each fileset is available
to the global namespace at its attachment point. You are responsible for creating
filesets and attaching them to directories in the global namespace. This can
be done at multiple levels. An attach point appears to a SAN File System client
as a directory in which the client can create files and directories (permissions
permitting).
Figure 1 shows a sample global namespace. In this sample, the global
fileset is attached to the root level in the namespace hierarchy (sanfs),
and the filesets (HR, Finance, Marketing, and CRM) are attached to the global
fileset, and the nested filesets (Assets and Revenue) are attached to the
Finance fileset. By defining the path of a fileset's attach point, you also
automatically define its nesting level in relationship to the other filesets.
