Hi Lawrence,

I was informed there is no mismatch, and since that is the case I was
curious since
we are using GigE as opposed to what we used to before (100mb ethernet full)
and the dsm.opt files were based on those settings could we adjust those
parameters
and is there any documentation or guides that says use different
parameters for GigE.

Thanks
Tim

We are using GigE and Curtis we are using  a separate nic for tivoli
backups.

Thanks

I would make sure whatever speed and duplex setting you have the nic

set to, you should set the switch port to match.  I would try to avoid
setting both to autonegotiate, as I have personally seen horrible
performance with that setting.  Also, run diags on network interfaces to
rule out any hardware problems.  Are u using a seperate nic for your
tivoli backups or are u using just one nic for all network communication
on these servers?

Subject: [ADSM-L] Wiindows 2000 and 2003 servers backups very poor

performance

Hello,


We have about 5 or 6 Windows Servers whose backups performance is

very

very poor these
backups start a midnight and run throughout the whole day and

sometimes

run for a couple days
I have been reading different options including the DISKBuffsize
option,  I know poor networking
performance can be caused by a number of factors and not sure which
parameter to look at first.

Here is an example of one of the clients dsm.opt file, They all
basically look the same and
the parameters matches TSM windows clients recommendations.
