FlashCopy on an IBM ESS ("Shark") starts at somewhere around $50,000 for a
very modestly configured array.  The cost increases as you add more disks,
and maybe even as you add cache!

A former client -- a University -- had been given a free used ESS, which
they had hoped to use as spare parts to upgrade their existing one.  They
were very disappointed to learn that the increased license fees for
FlashCopy made it prohibitively expensive to add the "spare" disks to their
existing Shark.  To my knowledge, those disks (and the cache) are still
sitting around gathering dust.

FlashCopy for FasT / DS4400 is likely to be less expensive, but you'll
probably have to call an IBM sales rep to find out how much less...  I very
much doubt that it is "free".

Btw, do you know if there are any additional licensing associated with
FAStT's snapshots feature?
