Do the math, 100 megabits/second nic turns out to be 12.5 megabytes/second
of data going to tape.  That's purely a max max speed which you never see in
the real world. So I thought if I could double up on nic's I could double up
on data to tape.

Before doing this, you should make sure that your single Ethernet adapter
is, indeed, the bottleneck.  For instance, if your backup and/or storage
node server CPU is running 90-100% busy (perhaps handling the IP traffic
containing your backup data coming in from clients via the LAN), or if your
backup client is busy, slow, or has many small files, then adding a second
Ethernet adapter won't help.

Where is your bottleneck now?  That will help us advise you.

If you're not sure, check out the NetWorker Performance Tuning book,
available (as are all NetWorker manuals) on the Legato web site.

Hope this helps.

Subject: [Networker] Second IP on Server

I am on a 100mb network.  Trying to make my back ups faster. My hp server 
has a single network interface card with two ports. I have a library with 2 
sdlt 320's rated at 16MB per second per driver. I am averaging 6 or 7 MB 
per second per drive. What I thought I could do is assign a second ip to 
the other nic.  Then go around and change half my host files so that half 
my servers would backup on the other ip, basically increase my input to the 
backup server. I did the experiment but networker is giving me a connection 
refused. The client recognises the fully qualified domain name and the 
second ip. I am a windows environment. Is there any configuration on the 
networker server that needs to done.
