This topic covers the general network and connectivity requirements for the Delphix Engine, including connection requirements, port allocation, and firewall and Intrusion Detection System (IDS) considerations. For platform-specific network and connectivity requirements, see the relevant topics under the Requirements section for each platform.

32768 - 65535

Required for NFS mountd and status services from target environment only if the firewall between Delphix and the target environment does not dynamically open ports.

Note: If no firewall exists between Delphix and the target environment, or the target environment dynamically opens ports, this port range is not explicitly required.

Firewalls and Intrusion Detection Systems (IDS)

Production databases on source environments (for dSources) are often separated from the non-production environment by firewalls. Firewalls can add milliseconds to the latency between servers. Accordingly, for best performance, there should be no firewalls between the Delphix Engine and the virtual database (VDB) target environments. If the Delphix Engine is separated from a source environment by a firewall, the firewall must be configured to permit network connections between the Delphix Engine and the source environments for the application protocols (ports) listed above.

Intrusion detection systems (IDSs) should also be made permissive to the Delphix Engine deployment. IDSs should be made aware of the anticipated high volumes of data transfer between dSources and the Delphix Engine.

SSHD Configuration

Target Unix environments are required to have sshd running and configured such that the Delphix Engine can connect over ssh.

The Delphix platform expects to maintain long-running, highly performant ssh connections with remote Unix environments.

Network and Connectivity Requirements for PostgreSQL

  • IP connections must exist between the Delphix Engine and the target environments.

  • The Delphix Engine uses an SSH connection to each target environment, NFS connections from each target environment to the Delphix Engine, and PostgreSQL client connections to the virtual databases on the target environment.
  • Once connected to a staging target environment through SSH, the Delphix Engine initiates a PostgreSQL replication client connection from the target environment to the source environment.

Port Allocation for PostgreSQL Environments

The following diagram describes the port allocations for PostgreSQL environments. It illustrates the ports that we recommend to be open from Delphix to remote services, to the Delphix Engine, and to the Target Environments.
