Chimera is the preferred name space abstraction for dCache. It is a thin
layer on top of a relation database (preferrably PostgreSQL). In contrast
to PNFS it is platform independent, scalable, and fully embedded in
dCache. By now, most dCache Tier I sites as well as many Tier II sites have
migrated to Chimera. PNFS itself is no longer maintained, although
dCache does still support using PNFS as a backend. We recommend all
sites to upgrade to Chimera as soon as possible.
Please study the migration
instructions and give it a try. You can evaluate the
entire migration procedure in a safe test environment.
More information is available from
our documentation area.
