Set up SNAP HA™ in any VMWare virtualized environment. In order to set up SNAP HA™ the following is required:
- 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 SNAP HA™ Controller node is required. This 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.
For more information about SNAP HA™ networking best practices, see section HA Design Principles.
For more information about common SoftNAS Cloud® installation procedures, see the document SoftNAS Installation Guide.
Setting Up SNAP HA™ for VMWare
After the above networking requirements have been fulfilled, SNAP HA™ may be set up.
- Navigate to the SoftNAS StorageCenter™ interface of the primary node.
- From the SoftNASSnapReplicate™ panel click on Add Snap HA.
- Enter the virtual IP of an unassigned VIP address in the storage VLAN subnet. Click on Next.
- Add the static IP of a third SoftNAS Cloud® virtual machine that will act as the HA Controller. It is recommended that this machine be deployed in fault tolerant mode.
- Click on Next.
- Click on Finish.
