How do I set up QLogic SanBox 5802V's for redundancy?

We currently have a QLogic SANBox 5802V in production and want to add another 5802V. I've been presented with three options by the QLogic support staff but they didn't do a good job of explaining the benefits/shortcomings of each option. Could someone help me choose the best option?

We need redundancy without losing throughput. I don't mind making extra manual entries onto the other switch if necessary. I was just hoping that there was a stacking option that still allowed for redundancy, but the support staff said that if one switch goes down in a stack, the other goes down as well. That doesn't sound right.

Guidance? Advice? Thoughts on the new hydrogen cars coming out?

I dont know much about Qlogic stacking - if it offers failover and single interface to administer whole stack go for it.
The shared zone in other pictures can be same general-purpose network you have to ESXis

In either case once failed over you get half speed by any means, though it keeps working and you have time to fix failed unit.

We ended up having to call QLogic support due to time constraints.

The answer was to create a shared zone set between the two switches and then stack them with two stacking cables. The zone set auto syncs across both devices and therefore provides redundancy in the instance a switch goes down. We successfully tested this at night by placing a switch in an offline status while leaving the other one running. The other switch kept the FC infrastructure running fine (hosts and SAN).

We repurposed last FC cabling year ago... for 10GbE... It is much easier to have one cable trunk set..

I only got one response and it didn't answer my question. We called QLogic support (which is free) and they answered our question(s).
