Backup traffic going over LAN instead of within SAN

Hi, I have a new Clariion CX3-40f with several hosts (file server, Networker backup Server etc) attached via Brocade 5000 switches.
I also have a CDL and an ADIC library attached to the fabric as well. I am using Networker 7.4.2 to backup the file server to the CDL and tape.

Here's the problem, when I start the backups the Gigabit NIC on the file server and the backup server go to 100% and stay there until its done.

Shouldn't the data just be moving over fiber within the SAN fabric instead of going out over the LAN? And why isn't it?

* I would like to make the file server a DSN, but its Win2008.

**I have posted this in the Clariion forum as well**

Where are the library and CDL connected? Only to the NW server? If you want to backup the file server over SAN, you have to turn it into a storage node (or DNS) and connect a tape drive to it. If not connected, data will flow over LAN.

Other option would be to make the disks in Clariion visible to the Nw server (maybe doing a raw device backup)

That's what I was afraid of.

I guess it will have to be that way until after 7.4.3 comes out.

Didn't you say in another thread that 7.4.3 will support Storage Node for Win2008?

I own a DSN license, but my client is 2008 server.

??? How is 7.4.3 related to what you have?

Yes, but somehow I could not see relevance to your question in this thread. When reading it from start it sounds as 7.4.3 would address what you stated in first message as problem which is not a problem at all. Someone reading this from aside will not be aware of your whole story and might get wrong idea.

Sorry. You're right. The only relevance 7.4.3 has is that it is suppose to support storage node on Win2008, hence solving my problem.
