@dafyre said in Introducing the Single Node Scale HC3 Appliance:
Will end-users be able to grow slowly? IE: Grow from one node to 2... and then eventually buy a third?
or would it be a jump straight from 1 node to 3 nodes?
Unfortunately at this time there is no means of growing from one to two. The jump is from one to three and one node at a time from then on. This is because of the need of a witness to avoid split brain of the cluster. One node avoids this by not having high availabilty, three and more nodes handle this by always having a witness. At two nodes there are complications that do not exist otherwise. So at this time, there is no two node option.
Except, of course, if you were in a situation where two nodes was useful through replication. That works with two nodes.
