The biggest problems that our hardware team report are:
a) lack of hot swappable drives means a lot of manual work to replace bad disks
b) the cabling is on the front, which is pretty much opposite of how the rest of our gear works
Our people do tend to bring down both nodes when working on them. But I think that's more of a safety precaution than a requirement. But those events are relatively short lived so usually not a big deal WRT block replication.
