Tetra Data Hub System Requirements

You must install a Tetra Data Hub on a network server or virtual machine (VM) that is dedicated to TetraScience (for example, the server or VM must allow TetraScience to remotely reboot the machine without causing any impact). The network server or virtual machine (VM) must meet these system, user, hardware, and network requirements:

Supported Operating Systems

64-bit versions of these platforms are supported:

  • Ubuntu 18.04 through 20.xx
  • RedHat 7.5 through 8.x
  • CentOS 7 or later

User Permission

You need admin (sudo) access of the machine

Minimum Hardware

  • 2 GHz+ processor
  • 8 GB RAM required, 16GB RAM recommended
  • 50 GB+ available disk space
  • 4 CPUs minimum recommended

Network Access and Bandwidth

  • Outbound Internet access
  • Minimum 1 port should be available (Each connector should have a dedicated port)
  • Minimum network bandwidth -100 Mbps network is required, but 1000 Mbps is preferred

Tetra Data Hub uses AWS SSM Agent. The instance running the Data Hub/SSM Agent must have outbound Internet access. The outbound Internet access connects AWS services endpoints.

All communication from the SSM Agent is outbound HTTPS to the SSM, and EC2 messages endpoints in the region where your instances are registered. The SSM Agent does not require you to open any inbound ports so inbound Internet access is not required.

Each Connector installed on the same Hub machine uses a different port to communicate with a Tetra Agent. To install Connectors, you need to set the minimum number of available ports to 1. If you are going to use multiple Connectors but ports are limited on one Hub machine due to security reasons, then you need to create multiple Hub machines and install Hub on each of them.



The Tetra Data Platform (TDP) uses server-side encryption for Amazon Simple Storage Service (Amazon S3).
