Configuring Availability Settings

Use the Availability page to view the redundant configuration of your system, and optionally deploy a second node to improve availability.

The Availability page displays the current Redundant Configuration of your system:

• Enabled — Both nodes are online; the system is redundant. If one of the nodes fails or is taken offline, the virtual machines (VMs) will automatically fail over to the healthy node. (For an overview of the levels of availability and failover on ztC Edge systems, see Modes of Operation.)
• Disabled — Only one node is configured; the system is not redundant. If the node fails or is taken offline, the VMs will be unavailable. To make the system redundant and improve availability, add a second node.

The Availability page also displays information about each node in your system. If only one node is present, you can click the + (plus sign) to add a second node for redundancy. For more information, see the adding a node guide for your system (or Adding a Node to a Single-Node System).
