to use an X410 node (or cluster) you need 7.1.1  But as far as I understand the node equivalency (node compatibility) feature is only applicable from 7.2 up.
Hello folks,  I have a 1 year old 10-node cluster that consists of X400 nodes. I want to add one node,  can i add one X410 node ?   Thank you
