I am in charge of a controller swap from a 3210 7-mode to 8020 7 mode. The 3210 is using the backplane for HA, but has the C0a/C0b open. I need a connection between chassis since the 8020 is the same configuration with 2 controllers in one chassis. If I use netapp 10GbE cables will the 3210 switch to the "C" ports if it sees a link? I'm not finding any information to support this scenario.
cannot say for sure but I assume that if the 2 controllers are in the same chassis, the interconnect link will go through the backplane (regardless of the 10G link in the c0a/c0b ports) but once you remove one of the controllers from the chassis, the link will start working through the 10G link
