We had CA Brightstor running at a major GM account for 3 months but turned out 
to be a failure when it came down to using diskpools as the primary pools and 
redirecting the data to the next level tape pools. CA does not have this 
automated at all and all they have is couple of utilities for one time 
migration and merging. Current Brightstor product does not have the ability to 
check the percent level on a disk pool and migrate the data to the next pool.
Essentially you need to write a script that would make use of these two tools 
and set it up that way which CA does not support.
On the positive side, Brightstor is very easy to implement, has better 
reporting, has brick level backup support for Exchange 5.5, has an agent for 
ingres.
Agent for SQL does pose minor problems with service pack levels but works.If 
you use it's own rotation scheme then it manages and expires the media very 
well but the problem creeps in with the schedules because for every rotation 
scheme, you could have only one schedule with a start time for all the backups 
and it would go from there hitting one server after the other.
Overall, this solution holds good for a midsize setup but certainly not for a 
large setup.
I hope this helps
