I would imagine that his throughput is bottlenecked by the number of
streams.
=20
8 streams seems like a lot to me, unless there's one helluva disk
subsystem. (or he has 4 - 8 disk subsets and is only pulling a stream or
two from each)=20
=20
I found performance hit the toilet when I went above 2 streams per RAID
group. (10 spindles in RAID 5 config, per disk group)

Shawn,
=20
You mean 0.8 to 5.0 megabytes per second per client, right?
=20
Have you already performed a test backing up only one client
with the backup server and drives
as idle as possible? In other words, do you know if this 5 MB/s
throughput is limited by some
other resource bottleneck or this is the highest that netbackup
client can send to the network?
=20
Thank you

All of our clients use gigabit interfaces. Our
throughput ranges from 800 kps to 5 Mps depending on file size on the
clients and number of streams running at the time. We run a max of 8
streams per client and 4 streams per drive using two drives. We have
tried tweaking the throughput using the streams but haven't spent much
time investigating any other method. If anyone has a system to tweak
the throughput we would like to try it.=20
=09
All systems are Win2K=20
Backing up files ranging from excel/word docs to Unix
file system backups and SQL database backup to 40 GIG.=20
1.5 TB total backup=20

Hello
=09
Is there someone on this list using gigabit interfaces
on the client machines?
If so, what has been the backup throughput? Is there a
special netbackup tuning
to improve performance?
=09
Thanks
