I have 100% absolutely zero experience with anything cDOT. I've only worked with 7-Mode. Having said that, in an effort to gain some experience with cDOT, we are attempting to stand up the 8.2.1 cDOT simulator (or vsim, or whatever).
We currently have 2 7-Mode simulators, and each of those have 4 NICs on them. I made (what I fear) was a bad assumption that the cDOT simulator would require the same amount of NICs, but upon setting it up, I see I have some additional interfaces that need to be set up (cluster admin, node admin....that's as far as I've gotten). So I'm just trying to figure out exactly what I'll need to get this guy up and running. Currently we were just going to set up a single node cDOT vsim, but now I'm beginning to think it might be a good idea to set up a 2 node vsim environment, so that we can see exactly how it would work.
Can someone give me their recommendations on # of NICs, or any other pieces of advice on this?
Can you tell me how you broke your NICs up? Typically we would set one for replication, one for vfiler, one for nfs traffic, and one for iscsi traffic. From what I'm gathering just based on running through the set up, it looks like 1 interface will need to be dedicated to cluster management, and another for node management.
