This is a bone of network contention (no pun intended),
Because nic switch vendors never seem to implement the autodetect spec
in the same and/or correct way. Depending on the manufacturer of the
switch/nic, sometimes you have to use auto on both, sometimes you have
to hardcode both, sometimes you have to hard code one but set the other
to auto.

Open the server's remote management website (http://servername:8008),
click the Set Parameters link, then the Communications link. It will
be in there. You can also set it at the console with a command

When we had a similar problem Servergraph/TSM told us the bottleneck was the
network I/O. Upgrading the TSM server to a gig ethernet card and switch
dramatically improved the backup times of our Novel clients.

As always, review the TSM Performance Tuning Guide.
TCPWindowsize is a classic network tuning knob which can have large
benefits where right value is chosen - which may require
experimentation.

Mark,
Thanks for the reply. One final question. Can I use the same
strategy if I have just one volume on the server? For example:
DSM1.opt
Exclude *:/.../*
Include SYS:Apps/.../*
DSM2.opt
Exclude
Hello,
We have a Novell client who's backup is taking to long
We added the Resourceutilization line (8) to the dsm.opt file
but it's still taking long. Does anyone have any suggestions
on what else I might take a look at or do that would help improve
the backup time. The backup starts around
The only thing in the dsm.opt that jumps out at me is the
MEMORYEFFICIENTBACKUP. That will definitely slow down backups, and should only
be used if the client being backed up really is memory-deficient. The other
thing is, RESOURCEUTILIZATION tends to have dimishing returns. I've found that
So, to follow up, should RESOURCEUTILIZATION never be set higher than the

there a way to establish multiple backup sessions to improve backup times? I've
traversed the
Well, the old saying is, never say never...
There are exceptions to what I said. Generally you only need to set
resourceutilization to = volumes +1. However, what if you're backing up 2
volumes, sys: vol1: , but have 5 tape drives available in your library? To
do multi-session restores
Troy, Thanks again!

Something I just ran across:
Solaris implementations may be experiencing degraded performance due
to debugging having been left on in the TSM device driver, as
shipped. Do an IBM site search on IC40302 for the recent APAR and
helpful Technote.

Hi all,
Windows 2000
TSM server 5.2.1
clients 5.1 - 5.2
Domino 6.0.3 soon to be 6.5.4
I'm in a bit of quandry, and I would like another angle on it.
The best performance I can squeeze out of our Domino backups is 10MB/s,
where normal backups over the same network reach 40 MB/s. A quarter of
I changed resourcesutilization from 5 back to 3, then backup
performance is still very good. I guess the root cause is the
tcpwindowsize that HP-UX does not support 128. Thanks for everyone's
help!!!

I have a performance issue here, any input would be greatly appreciated.
TSM Server: 5.3 on AIX 5.3
TSM Client: 5.2.3 on HP-UX B.11.11
TSM Storag Agent 5.2.3
Tape Library: IBM 3584 LTO2 with 12 drives
The backup throughput is not good.
