In my amateur opinion, it sounds like someone was hollering about 'system 
slowdowns over the network' and started pointing fingers. As backups are the 
least sexy operation in an IS department, you get to shoulder the blame for 
latency/traffic on the network.

What they probably want to do is fit all the servers with two cards with 
different IP addys, for example: 10.1.x.x (existing)  and 192.168.x.x (new). 
That way, all of your existing clients and infrastructure can still chat 
happily on the existing network (10.1), and the backups can pull data across on 
the new network (192.168). Ideally, your routers (depending on your layout) 
should figure this out without too much hassle---unless you have some heinous 
bridging and/or firewall concerns.

Of course, you may need a DNS server specifically for that segment (don't want 
192 traffic routing to 10 addresses, do we?). It should work spiffy, after the 
initial unpleasantness.

Does that make any sense at all?

I'm not really sure how to even ask this question, but I'll give it a try 
anyway.

Our management had a meeting yesterday and after it was all said and done, they 
had a few questions for me regarding moving all of our Veritas Netbackup 
functions off the main LAN and utilizing a separate and dedicated backup 
network. (BAN?)

My understanding is that everything will have its own dedicated network cards, 
fibre cabling and server connections.  I don't think that would be a problem, 
but they asked a few questions about going through a router off of the SAN and 
will the backups still run correctly through the router and what kind of 
performance issues might we deal with.

I honestly don't really know what it is they are asking or to answer these 
concerns so I was hoping this little bit of information I have might jog 
someone on here to make sense and give me some feedback to pass on to 
management about a strategy or if it is even a good idea.

Sorry that it is rather vague, but I'm just in the initial stages here myself 
and was hoping for some outside input.

Thanks all,
Dave
