Network requirements
-
One or more dedicated and separate peer-to-peer Interconnect networks are required for internal cluster communication.
-
All cluster servers should be connected to Interconnect networks.
-
All servers should have fully qualified domain names (FQDN) and the ability to communicate with each other at required speeds.
-
The IP address of each server should be known.
-
Ping access to any server (ICMP) should be provided.

For online ADPG installation, access to Arenadata Cluster Manager deployed on a dedicated server is required. See the Install ADCM article for details on how to install Arenadata Cluster Manager.
