Multi-node with HA Deployment
|
|
=============================
|
|
|
|
Production environments typically require high availability, which
|
|
involves several architectural requirements. Specifically, you will
|
|
need at least three controllers, and
|
|
certain components will be deployed in multiple locations to prevent
|
|
single points of failure. That's not to say, however, that you can't

|
reduce hardware requirements by combining your storage, network, and controller
|
|
nodes:
