ReadyNAS nic teaming over dual switches

Hi,

I am in the planning stage of trying to deploy a 2 node Failover Hyper-V environment and wanted to use two of the Readynas boxes for iscsi targets, so my question is can the Readynas product nic team over independent switches, they can be linked if necessary, do you know what Readynas/switches I would need?

I was looking at the Readynas 316 and probably the latest smart switches, but reading around I am thinking these might not be enough.

Thanks.
