Hi I would like to know is it possible to have a Physical Fault domain with a different MTU as a Virtual Fault domain that shares the same ports. According to what I see in DSM config options it "seems" possible. But would like to know if anyone has done this. The reason is that I need a different MTU for replication to a DR site, but do not have any additional free physical NICs to create a new dedicated physical fault domain.
Currently I have two physical fault domains with 4 ports each.
So the plan is to "steal" all physical ports from one of the current fault domains, and create two new fault domains from them: one virtual, one physical, each using the same physical ports (but different vlan tag for each fault domain, and different MTU - one standard frames, one jumbo). The physical one would be for the new replication traffic (MTU 1500) and the virtual one would be used as a standard front-end I/O fault domain (MTU 9000)
I asked copilot a while back and presented my plan to them; they basically said "it should be possible", but that's not overly convincing. A little disappointing to be honest from supposedly the best support around.
Thanks all
