Actually the new DD OS upgrade alone is supposed to provide better performance. We just did the upgrade and are looking at some other fun facts with HP-UX' NFS implementation.

You need a license per restorer so we would have needed 2. At the time I understood that it was of more use for folks still vaulting data to tape from the DD's. I understand that when combined with the new DDOS release, OST now provides considerable performance improvements with regard to throughput. We may revisit the idea if the prices have changed.

I will implement it to a customer within the next month. Also with the latest firmware, DXi7500 use OST to replicate to another DXi7500 and netbackup is aware of the replication.

It's not NFS or CIFS, it is its own transport. It is also not VTL. Think of it as a more intelligent DSU. In the case of DD & Quantum, the data is sent over IP. With Falconstor, the data is sent over Fibre Channel. With DD boxes (which is what started this conversation), the first improvement you'll get simply by switching from NFS/CIFS to OST is a significant increase in performance. With all systems that support OST, you also get what NBU calls "optimized deduplication," where NBU tells one OST device to copy a given backup to another OST device. The OST device (in this case, the DD box) will use dedupe and replication to get the data there. Once there, it informs NBU. Now NBU knows about both copies, just as if it had duplicated it via bpduplicate. Nice, huh? The nice thing that OST is supposed to support is tape-out functionality, where an OST device can copy it's backup to tapes and tell NBU which tapes got which backups. Again, just as if it NBU did the copy.
