Quite a project. Sepaton has customers that store Petabytes of data on
their VTLs. Sepaton claims performance of:

* 1.2 Petabytes per VTL (without compression)
* RAID 6 protection
Obviously you need more information on the requirements. Good luck!

Here is my response to an earlier question on sizing a VTL. I have been
using a 10GB tape volume size for a couple of years and have not seen a
reason to change. I originally chose 10GB because ISM recommended that
size when using sequential file devices.
Yes that is an approach that will work.
Try:

BACKUP_DATE,STATE,cast(DEACTIVATE_DATE as date) as

You usually do not use RMAN to create a backup file locally on the
client and then back up that file to TSM. Instead, via the TDPO api,

1) connects to the TSM server
2) generates a file name
3) checks to see if that file name is currently in use
4) sends a stream of data to the TSM server
