Network requirements
Overview
This topic covers the general network and connectivity requirements for connecting the Delphix Continuous Data Engine to the source, staging, and target environments. Ensure all ports are open and available before adding an environment to the engine.
Delphix Continuous Data Engine Connectivity
During the installation of the Delphix Continuous Data Engine, our documentation provided various ports that must be opened. Consult the Deployment section’s Network connectivity requirements and Deployment for additional engine-specific information.
NFS mounts on environments
Delphix Continuous Data Engine shares its storage space with the staging and target environments using NFS mounts.
Protocol | Port number | Use |
TCP/UDP | 111 | Remote Procedure Call (RPC) port mapper used for NFSv3 mounts. |
TCP | 1110 | Network Status Monitor (NSM) client from target environment to Delphix Continuous Data. |
TCP | 2049 | Network File System (NFS) client from target environment to Delphix Continuous Data. (NFSv3 and NFSv4). |
TCP | 8341 | Sending LogSync data from source to Delphix Continuous Data (for LogSync). |
TCP | 8415 | SnapSync control and data from source to the Delphix Continuous Data. V2P control and data from the target environment to the Delphix Continuous Data. |
TCP | 54043 | Client mount daemon (NFSv3 only). |
TCP | 54044 | Lock state notification service (NFSv3 only). |
TCP | 54045 | Network Lock Manager (NLM) client from target environment to the Delphix Continuous Data (NFSv3 only). |
UDP | 33434 - 33464 | Traceroute from the target database server to the Delphix Continuous Data (optional). |
General environment connectivity
Environments share a common set of ports that must be opened to establish communication with the Delphix Continuous Data engine.
Data source connector connectivity
Many connectors have their own set of connection requirements to consider due to database differences. We recommend navigating to the connector’s specific documentation on environment creation to identify other network requirements.
Due to these differences, many connectors support a HostChecker (sometimes called HealthChecker) utility to ensure the validity of the newly created environment. Consult the connector’s documentation for more information.
Secure Socket Shell (SSH) connectivity
Linux and Unix environments connect with the Delphix Continuous Data engine over Secure Shell Protocol (SSH). This connection is performed through the sshd (OpenSSH Daemon) program. The Delphix Continuous Data Engine expects to maintain long-running, highly performant ssh connections with the environment.
Allow the following inbound port for SSH connection to each environment.
Protocol | Port numbers | Use |
TCP | 22 | SSH and SFTP connections to the source, staging, and target database environments. Starting with Continuous Data 16.0.0.0, Delphix will use SCP connections only if SFTP is unavailable. |
Delphix connector connectivity
Windows environments require the Delphix Connector to communicate with the Delphix Continuous Data Engine. The Delphix Connector is installed on all target environments. Source and staging environments will use the target environment’s connector for communication. Refer to the Delphix Connector documentation for additional information.
