With all the missteps NA has had getting C-mode out the door I don't think they can really push it on anyone. Remember Auspex 1.8. Where's Auspex now?
A very fond memory, if triste; the months that felt like years that I spent trying to master the art of handholding the recovery of lock state after failover, and appreciating the cleverness of the multicast tricks and nfs protocol.shortcuts, taught me lessons about how NFS really works (when it does) that will last me.
H-A is great when it works, but I've rarely seen implementations that aren't seriously lower availability than the single-point-of-failure system they try to replace.
Though I think what did for Auspex wasn't their ambitious H-A, it was NetApp's ability to cling tenatiously to the Juggernaut as Moore's Law drove costs of processing, memory, and bandwidth down, and down, and ever down.
