Renee, We're testing OST as I write this !! We've actually been testing OST and the new dedupe in NBU 7.0. We've been running our exchange backups to an OST storage unit and have seen higher throughput speeds compared to our regular CIFS backups in the limited testing we've done (40mb./sec average compared to 20-25mb/sec). We're leaning towards it being worth the licensing fee to shorten our backup windows, even by a small amount.
The built in dedupe works great for windows OS backups but didn’t work too good for our exchange backups (the default fragment size worked against us with exchange data). Also the throughput to disk attached to the media server is much higher than we get to the Data Domain appliances (we hit a peak of 70mb/sec on some of those backups) but they are faster disks so we'd expect this. Our testing seems to be showing that the OST will be used on data that we continue to send to the data domains but we'll be able to push a lot of our backups through a couple of additional media servers to some dumb disk, using a mix of client side and media server dedupe. I'll update some more when we have some more testing completed.

(Especially if you are running NBU 7) Can someone give me a rough idea what kind of performance numbers you are getting....just looking for an average mb/s per stream on typical backup jobs. Don't need a lot of detail, just wanting some rough ideas.
