I'm brand new to Netapp products and actually new to storage all together. I just recently purchased a fas2020 for my office. I'm looking for some basic networking guidance. The filer is an active/active configuration. Controller 1 will be used CIFS data and controller2 will be used for iSCSI data. Each controller as 2 ethernet ports and i have 2 managed gigabit switches in place.
My uncertainty is how to network the controllers. My thought is to connect e0a of controller1 to Switch A and e0b of controller1 to Switch B to prevent a SPOF. The same would be done with Controller2.
With this, i would make the 2 ports of controller1 into a VIF and the 2 ports of controller2 into a second VIF. Does this make sense? Does this follow best practice? Any best practive articles or guides relating to this type of setup would be really helpful too. Like i said, this is all new to me and i want to make sure i'm doing it the right way.
Thanks in advance,

Hi Nick and welcome to the Communities!

Yes, it does make sense.
Did you have a look at this thread: http://communities.netapp.com/message/29431#29431?

Cross-stack LACP is a nice have, not a must.
Static multimode vif + non-stackable switches will work just fine for failover purposes, yet you will be limited to one active link - which may, or may not be an issue in your particular case (1x 1Gbit is more than enough for e.g. random access)

I found out that the my switches are not stackable which throws a wrench into my plans. I'll just have to create my VIFs on the same switch and be vulnerable to SPOF until i can get a pair of managed switches that are stackable.
Thanks for your help.

Hello again....I ran into another problem. I got the VIFs up and running and everything was working good until i rebooted the controllers. After reboots, both interfaces (e0a and e0b) are in the down state and there's OnTap knows nothing about the VIFs when i run the vif status command. Do i need to save this configuration? If so, what is the command? I have not come across this in all of my readings. Any help would be much appreciated.
