Veritas is a good product. I used it.

Warning:
The Veritas software costs US$25K, but you may spend more dollars for the support.

It is very difficult to get good tech guys in New York. In one of the site, SUN+ORACLE+VERITAS took more than 6 weeks to setup a disk array system (RAID 1+0).

Before you purchase the software, talk to Sales Rep about the support, and training. Visit the office and figure out how big it is.
