Nope. Not even close. The MIP/MSU/M-thingy cost of HSM in a decent sized TMM environment is bloody horrendous. Outrageous even. Not to mention the (mainframe) DASD cost. The ML1 occupancy is way too expensive. And it gets in the way of all the other HSM housekeeping - *and* it's all charged at mainframe MIPs rates. Just a non-optimal solution. TMM for *SMALL* usage works. Once it grows, virtual tape wins hands down.
