Ambrose, I have setup Tape San's before but not with Netapp. I may be able to help a bit here:

1) You will need to license the Brocade switch for Quickloop mode. You will need this because the Netapp logins into the fabric as a arbitrated loop. Set the ports the Netapps login into as Arbitrated loop mode.

2) How is the Overland Data logging into the fabric? Usually they will login to the switch as N_Port but check with the vendor. I believe Overland Data use the ATTO bridge. If they are N_Port they will login as full fabric.

3) I would zone each Netapps Fibre loop as a separate zone. For example, Zone 1 would consist of Netapp 1 FC port and both the Overland Data's FC ports. The second zone would consist of Netapp 2 and both the Overland Data's FC ports.

Hope this helps, Mike

We are having enormous problems configuring our new tape libraries with our filers. We keep getting different answers from people and I hope that someone on this list has something similar in production and they would be willing to share their information.

Here's what we hope to have running: 2 F840c's 1 Brocade 2400 2 internal fibre channel bridges inside an Overland Data library a few other servers on the switch NetVault with dynamic drive sharing option

So, should everything be fabric, do we need to zone, any other ideas?

Thanks for your time,
