Yugabyte network and connectivity requirements

Ensure that the requirements for Delphix Continuous Data Engine network connectivity are met before you proceed further. This page addresses YugabyteDB connector-specific network and connectivity requirements.

Ports for Yugabyte connector

SSH connectivity to staging/target host

Staging and target environments are required to have sshd running and configured for Delphix Continuous Data Engine to connect over ssh.
The Delphix Continuous Data Engine platform expects to maintain long-running, highly performant-SSH connections with the host environment.

Whitelisting inbound port for SSH connection to target host

Creating NFS mounts on the target host

The Delphix Continuous Data Engine shares its storage space with the target host using NFS mounts.

Protocol	Port Number	Use
TCP	22	SSH connection to the target database environment.
TCP/UDP	111	Remote Procedure Call (RPC) port mapper used for NFSv3 mounts.
TCP	1110	Network Status Monitor (NSM) client from target hosts to the Delphix Continuous Data Engine.
TCP	2049	NFS client from target hosts to the Delphix Continuous Data Engine (NFSv3 and NFSv4).
TCP	54043	Client mount daemon (NFSv3 only).
TCP	54044	Lock state notification service (NFSv3 only).
TCP	54045	Network Lock Manager (NLM) client from target hosts to Delphix Continuous Data Engine (NFSv3 only).
UDP	33434 - 33464	Traceroute from the target database server to the Delphix Continuous Data Engine (optional).
