Hi TSMers,

Miles, the answer to your question is the same reason, that Rene has given,
it more for splitting traffic but in our case we have put the application
traffic on the normal 10/100mb card and the backup traffic on the gigabit
card.

Thanks again guys for all your answers, it has definately come in handy.

One last question, when I backup data on the gigabit card it backups up 1gb
per minute and my restores are 1gb per 5 minutes... do any of you guys have
an idea as to how I can improve the restore rate....Please note that we do
not have a san and this is why we have opted to go for the two lans......

Thanks again in advance for all your help.


Regards.

Lindy

Miles,

in fact this what we do here, except we have more than one gbit adapter on
each tsm server, a way of dividing traffic and defining direct connections
to different vlan's (less hops),

best regards,

rene

Hi there,

I have a related question: what is the benefit to using two interfaces? Why
not just use the gigabit card, for all TSM traffic? Is it better to keep the
high-speed backups on the giga bit interface and keep the scheduler traffic
on its own? It seems like a lot of extra work and confusion.

Consequently, I have a very similar setup, and I'm always interested in ways
to make the backups run faster.

Thanks Miles

Hi there,

I guess you already got the right answer from Rene. Just add another entry
to dsm.sys with tcpserveraddress pointing to the ip address of the GB card.
The scheduler will be started with the default entry and handle connections
through the 10/100MBit network while you will need to start your backup
client either with the option "-se=gbit_address" or with using an
alternative dsm.opt file employing the "-optfile=dsm_gbit_address.opt"
option. Also, do not forget to define or modify your schedules
appropriately by setting the option field for the relevant schedules to one
of the above.

CYA
