You should see 1 dbvol indeed. We have our ADSM diskpools and db on an ESS
subsystem. This ESS is attached thru 4 fibers so bandwith or i/o-wait should
not be the problem.

Our dialy backup process involves many systems, about 75 NT boxes with user
data and some 50 AIX boxes. THe user data mutates very much and on many AIX
boxes we do offline oracle archives.

Our server is an S70 with 4GB ram running aix 4.3.3 and ADSM 3.1.2.90.
