SSDs should work well for the DB and active log. As for the filesystem,
you'll want to use ext4. I don't know that IBM has documented filesystem
restrictions for DB2 wrt TSM, but certainly for standalone DB2 they
recommend only ext2/3 (and presumably now ext4) and reiserfs due to their
direct I/O implementations:
