What David wrote meets our company too. We have nearly the same size of
data managed by ADSM/MVS. (600 GB BAckup/Archive, 10 GB Database, 1 GB
LOG)
The ADSM server is one of our most excessive CPU users and I really can't
belive a 50 TB system. But if its true Im very interested how that
installation is configured.
