VMWare HA Considerations

VMware has a few requirements specific to setting up high availability through SoftNAS. SnapReplicate can be performed as described in SnapReplicate, and requires only two nodes. Setting up SNAP HA™ in any VMWare virtualized environment requires the following:

Two SoftNAS Cloud® controller nodes for replication and their corresponding IP addresses (DNS names) and networking credentials.
A virtual IP within the storage VLAN subnet (see HA Design Principles for more information).
An additional SoftNAS controller node is required, to act as an HA Controller. This SoftNAS SNAP HA™ Controller node is necessary, as it acts as a 3rd party witness and controller to all SNAP HA™ failover and takeover operations.
Replication must be set up between the two SoftNAS Cloud® controller nodes.
