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.
