Re: DTL vs LTO open discussion
LTO drive (230):
* 15MB/s native sustained transfer rate
* 30MB/s sustained transfer rate assuming 2:1 compression.
DLT 8K:
* 6MB/s native sustained
* 12MB/s sustained transfer rate assuming 2:1 compression
(data taken from specification files of external HP site).
LTO drive is definitely superior in transfer performance, so much though that on many systems the system can't keep up with the drive to keep it streaming.

Re: DTL vs LTO open discussion
Overall, we found SDLT to be technically superior. I thought it was really cool to watch a SDLT tape drive do a backup while being shaken in a paint mixer! No errors!
Unfortunately, HPs lack of vision with repect to SDLT, we decided to go with Veritas Netbackup using ATL robotic drives. Preserving our investment in DLT7000 and DLT8000 was also a factor.

Re: DTL vs LTO open discussion
I was in a situaton similar to yours. We was planning for a new backup solution and had lot of DLT tapes from our old systems (DLT400 and DLT7000).
The question was DLT8000 or LTO.
I choosed LTO because a LTO solution was mutch cheper (samller library and fewer OmniBack licenses). I plan to use DLT tapes (and some of the old equipment) for archive purposes. There is a problem because OmniBack dont support copying data from a LTO to a DLT device, I need to run a extra backup session for this archiving.

Re: DTL vs LTO open discussion
Addind LTO libraries will reduce the backup window, as well as will help you to success on backing up all of the required data.
We have DLT & LTO, LTO libraries do the backup of those servers with some hundreds of GB's of on line storage. DLT are now our backup player for the backup infrastructure.
