SAP Netweaver 7.5 Cluster HA Info

  • Each of the cluster nodes in the cluster must have its own local disks and have access to shared disks that can be reached by the cluster nodes via a shared bus.

  • The cluster nodes of the cluster must be connected by a private and public network: 
  • ○ The public network enables communication from the cluster nodes of the cluster to other resources in the local area network (LAN). 
  • ○ The private network enables internal communication between the cluster nodes. In particular, it enables the Cluster Service running on all cluster nodes to regularly exchange messages on the state of the cluster nodes so that the failure of resources is quickly detected
