eth1 for private traffic (heartbeats, synchronizations, and file replications).With the help of the vSphere web client, you have to create a new network that will then serve as the communication channel of the VCSA-HA cluster.Д®ach VCSA node will then have two network interface cards (NICs): There's a bit of configuration necessary at the network level. VMware VCSA 6.5 High Availability configuration Network settings ^ Because the database uses synchronous replication, there is no data loss that is, the recovery point objective (RPO) equals zero.

In case of a hardware or software failure related to the Active node, the Passive node takes over automatically, and becomes the Active node. Please view the diagram below for the relationships between the nodes. Quorum (also called Witness) node вЂ“ This node serves to solve split-brain scenarios and solve inconsistencies within the distributed system, which has replicated data between nodes.Passive node вЂ“ This is an exact copy of the Active node, which constantly receives updates from the Active node.The Active node is serving admins' requests, and provides the common services and operations within the vSphere environment. Active node вЂ“ This is the production VM.It is an automated clustered solution allowing you to maintain the infrastructure services in case there is a hardware problem or the main, Active node is isolated within the cluster. The VCSA-HA feature works as a cluster of three VMs.
