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:
