Re: [Networker] How to improve performance

As I have mention in my Earlier mail ,
I am using SAN backup with Brocade Switch , I am not using GB Network .
Two clients in question are Direct Storage Nodes connected to SAN Switch by
LP10000 HBA card and L180 is also connected to Brocade switch Via Fibre .
ALL the Six LTO-2 drives are having separate Fibre connection .
On Server Side I have LP9000 Card on V440 Solaris 9 server also connected to
SAN Brocade Switch via Fibre .
Which means my Network has 2GBps Speed .

What kind of network do you have? Make sure to increase the number of
streams on each drive. With a 100Mb network you should get upto
11-12Mb/sec and with GigE network you should see a speed of at least
more than 35Mb/sec on each drive and with LTO-2 you should be faster but
network is the most important factor.

Hello ,
I have recently installd new Networker Server on Solaris 9 with L180 of
8
Drives .
Enviromment .
Server Solaris 9 , V440 2 CPU 4 GB
Brocade Switch .
L180 and Lto-2 drives
Lp9000 HBA card on Solaris
LP10000 card on Windows 2000 and windows 2003 cluster DSN's .
I am backing the two DSN on this networker Server , these two were
backed up
before by Veritas backup exec and time was 3 hours and 5 respectiveyl
for
80 GB and 260 GB data size .
Now it takes 7 hours .
I need help in making this backup faster . backup speed sometinmes goes
as
slow as 300kb/s and sometimes it goes to 45 MB/s (!)
Following is just an idea for you to understand characteristics of
client .
