	The network subnet used for heartbeat activity should not be used for any other purpose besides the heartbeat. Using the above example, the network of 10.3.x.x/16 and 10.4.x.x/16 are being used for the heartbeat traffic. Traffic for client communication such as NFS/iSCSI traffic to the system via the storage pool virtual IP (see next section) must be on a separate network, for example, 10.111.x.x/16. Mixing the HA heartbeat traffic with the client communication traffic can cause a false-positive failover event to occur.

	Both systems must be in the same grid before the Site Cluster can be created. Grid creation takes less than a minute and the buttons to create the grid and additional systems to the grid are in the ribbon bar. QuantaStor systems can only be members of a single grid at a time but up to 64 systems can be added to a grid which can contain multiple independent Site Clusters.

	The Site Cluster name is a required field and can be set to anything you like, for example '''ha-pool-cluster'''. The location and description fields are optional. Note that all of the network ports selected are on the same subnet with unique IPs for each node. These are the IP addresses that will be used for heartbeat communication. Client communication will be handled later in the Creating a Virtual IP in the Storage Pool HA Group section.

	'''Any cluster intended for production deployment ~~must~~ have at least two heartbeat Cluster Rings configured.''' Configurations using a single heartbeat Cluster Ring are fragile and are only suitable for test configurations not intended for production use. Without dual rings in place, it is very easy for a false positive failover event to occur, making any network changes likely to activate a fail-over inadvertently.
