Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

You got me. I've never made such analysis. It's more a case of "common
sense agrees with general recommendations agrees with general anxiety" ;-)

I'ts also that I'm fairly certain that if you do use a switched network
for you DRBD links, it is unlikely to be dedicated (because then it
would be almost trivial to remove the switch from this piece of your
setup). Again, I've been in situations where you cannot have a dedicated
link, and I sympathize, but it's a painful choice and I encourage
everyone to refrain from it.

I cannot comment on the sense (or lack thereof) in switching your
dedicated links. Your point appears valid.

Cheers,
Felix
