Can anyone provide insight to how they use deduplication within TSM.

TSM with SW based deduplication, no HW deduplication

TSM with no SW based deduplication, using HW deduplication

TSM with both SW and HW deduplication

The only major restriction that I have read is that TSM file based primary 
storage pools should
not be deduplicated at both SW and HW levels.

Any insights appreciated!

Thanks,
