I am curious what kind of problems you are running into.  At the TSM
Symposium at Oxford this year, IBM indicated that they were going to
further develop the serial access disk support in TSM.  And, TSM 5.3
just added the ability for a SAD devclass to span multiple
filesystems.  After hearing this, we have been leaning towards
investing in inexpensive disk managed by TSM rather than buying a VTL
appliance.  I'm interested in other's comments about where,
specifically, they are having problems managing SAD directly by TSM.
