I see about 5mb a second when using DLT7000s.
Of course, HP requires (suggests) they be on a dedicated
SCSI channel. I see as little as 4MB a second on our slowest
machines, and up to about 6mb a second on the fastest machine
with the INTER option turned on and data compression enabled
on the tape drive. The specification for a DLT7000 is only 5mb
a second (as I remember.) I usually get good compression since our
data bases have lots of empty records and lots of space filled data,
etc.
The only way I would get less than 1mb a second, would be on a busy system
running the store job at low priority, in which case 827kb/second might
be quite reasonable.
What model Hp are you running? How much memory? What is your I/O
configuration?
What store options are you using?

Subject: [HP3000-L] Increase the throughput on a DLT single tape drive?
Hello,
Does any one know how to increase the throughput on a DLT single tape drive?
HP3000 throughput is 827k/s on the DLT now.
