Configuring high availability in SoftNAS® on Azure is a simple process. It involves two nodes with defined IP addresses, and a third human-configured virtual IP to establish a heartbeat between the two instances. However, in order to provide our customers with our No Downtime Storage Guarantee, your two instances will need to be set into an Azure Availability set. We will cover this and more in the sections to follow.
Note: Only a single HA pair can be configured per subnet.
