Yes. No. Might be. ^L The concept of geo cluster is cluster of cluster, where the local cluster handles local issue using local timing (seconds), while the geo handles geo issues with much wider timing constrains (minutes, if not hour(s)). A geo setup needs a minimum of 2 sites + an arbitrator site. The arbitrator can be a single node (even a small VM) with the cluster stack running, if only used as a plain arbitrator. In theory you could run without an arbitrator, if the admins are the arbitrators. The other sites needs a cluster stack running, of course this will work with a single node cluster, too. Wonder what setup needs geo redundancy but no local clusters, or what setup needs booth but isn't geo. greetings Kai Dupke Senior Product Manager Server Product Line -- Sell not virtue to purchase wealth, nor liberty to purchase power.
