Cluster Hardware
The cluster hardware configuration consists of two nodes and a shared disk array. The shared disk array provides higher resilience to disk, controller, and cable failures. The two nodes are also interconnected on a private network. This enables the nodes to monitor each other's health and synchronize the allocation of services and resources.
Each node has one or more public network interfaces that connect the node to a corporate network, along with a private network interface that connects the nodes to each other.
