Network and connectivity requirements for SAP ASE environments

General outbound from the Delphix engine port allocation

General inbound to the Delphix engine port allocation

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.

Connection requirements for SAP ASE environments

• The Delphix Engine uses an SSH connection to each source environment and SAP ASE client connections to the SAP ASE instances on the source environment.

• The Delphix Engine uses an SSH connection to each target environment, NFS connections from each target environment to the Delphix Engine, and SAP ASE JDBC connections to the virtual databases on the target environment.

Port allocation for SAP ASE environments

The following diagram describes the port allocations for SAP ASE 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. 

Refer to Managing SAP ASE Environments for information on SAP ASE environments. The Delphix Engine makes use of the following network ports for SAP ASE dSources and VDBs:

Outbound from the Delphix engine port allocation

Inbound to the Delphix engine port allocation

Port allocation between source and staging target environments

Port allocation between staging target environments and shared backup fileserver

AppData port requirements

The use of AppData requires the following ports/protocols. Two important notes about these specifications:

1. The next release of the Delphix Engine will significantly augment the port/protocol utilization of AppData. The upcoming-only requirements have been marked with a *.

2. AppData V2P uses RSYNC to export to the target. RSYNC between the target and Delphix Engine is not required for general virtualization usage. The V2P-only requirements have been marked with a ^.
