A really good reference for this type of configuration is the Cisco document "VMware vSphere 5.1 on FlexPod Data ONTAP Operating in 7-Mode Deployment Guide", its a comprehensive guide on how to set everything up, including commands and config file listings.
Is vPC usually enabled or disabled in normal circumstance? what impact on the switch if I wanted to enable it? The reason I am asking these is because our networking guys told me that two ports in LACP could not be connected to two different NX switches. So, I am wondering what difficulties are to stop them to do so.
You sounds pretty familiar with tht sese options. you are right, we should talk to networking guys, but we heard different things from them, so, that's why I wanted to get some ideas myself.
It sounds a lot of efforts or costly on networking side. Then what we can do on NetApp side? If we don't go with vPC approach on network side, what can we do to resolve the single point failure on the switch? when tthe switch went down, it will cause the entire LACP (2 ports) going down as well.
currently, we are using 2-ports LACP group on each 2-node HA filer, A vlan is created on these two ports on each filer, so, two vlan's from two filers respectively are pointing to two different switches. If one switch went down, and then we will lost one filer, since as I understand it, in case like this, the failover would not happen.
Could you please elabrate your idea more, or recommend any document to prevent the single point failire on the switch?
