I am running TSM 7.1.5 on AIX 7.1.  My TSM DB is currently made up of five 
120GB filespaces.  I need to dramatically increase the size of the DB as we 
prepare for dedup.  I know I can have 128 DB filespaces.  What, if any, are the 
performance implications of just adding more filespaces vs staying with a 
smaller number of much larger filespaces?  The filespaces are SAN attached XIV 
with the data spread over 180 drives.
