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.
