Fabric Minimum System Requirements for Development and QA Installations

Introduction

• This document provides information regarding the hardware, software and the operating system requirements for Fabric installations.
• TDM installation is based on Fabric with the additions of TDM library and PostgreSQL installation.

Fabric Execution Servers - Node Specifications

The Fabric server installation is a Linux-based solution. A dedicated servers for Fabric instance is prefered. Following a sizing process, the exact number of nodes for each environment needs to be determined .

Minimum System Configuration for Each Fabric Node Server

Software Requirements:

Operating system:

• RedHat (version 7 or higher) based distribution (for example: Centos, Oracle Linux).
• Ubuntu Server, version 18.04 or higher.

Hardware Requirements:

Example of Cloud Supported Instance Types:

For all installations, the FS configuration must be as follows:

• Volume of 150G /opt/apps/fabric/ - will be used also as the home directory for a Fabric user.

Kafka Server Node Specifications

The Kafka server installation is a Linux-based solution. A dedicated servers for Kafka instance is prefered. Following a sizing process, the exact number of nodes for each environment needs to be determined.

Minimum System Configuration for Each Fabric Node Server

Software Requirements:

Operating system:

• RedHat (version 7 or higher) based distribution with latest patches (for example: Centos, Oracle Linux).
• Ubuntu Server, version 18.04 or higher, with latest patches.

Hardware Requirements:

Example of Cloud Supported Instance Types:

For all installations, the FS configuration must be as follows:

Volume of 50G /opt/apps/kafka/ - will be used also as the home directory for a Kafka user.

Cassandra Server Node Specifications

The Cassandra server installation is a Linux-based solution. A dedicated servers for Cassandra instance is prefered. Following a sizing process, the exact number of nodes for each environment needs to be determined.

Minimum System Configuration for Each Cassandra Node Server

Software Requirements:

Operating system:

• RedHat (version 7 or higher) based distribution with latest patches (for example: Centos, Oracle Linux).
• Ubuntu Server, version 18.04 or higher, with latest patches.
• Python version 2.7 (this is a Cassandra limit; until Cassandra version 4.0.x - Python version 2.7 is the latest supported; newer versions of Cassandra are not yet certified by K2view for Fabric)

Hardware Requirements:

Example of Cloud Supported Instance Types:

For all installations, the FS configuration should be as follows:

• Volume of 200G /opt/apps/cassandra/

PostgreSQL Server Node Specifications

• PostgreSQL is required for TDM projects only.
• K2view supports PostgreSQL version 9.6 & 13.x .
• PostgreSQL can be deployed in one of the following two ways:
  • On-premise as a virtual or physical machine.
  • As a cloud service (SaaS)

Suggested System Configuration for PostgreSQL Server

Software Requirements:

Operating system:

• RedHat (version 7 or higher) based distribution with latest patches (for example: Centos, Oracle Linux).
• Ubuntu Server, version 18.04 or higher, with latest patches.

Hardware Requirements:

Example of Cloud Supported Instance Types:

• GCP Cloud SQL PostgreSQL - read more here
• Azure Database for PostgreSQL - read more here

Fabric Studio Requirements:

Fabric Studio is used to configure, manage and control the Fabric server operation and its installation is Windows-based. The application can be installed locally on either a workstation or a server with Terminal Services for RDP connection.

Minimum System Configuration

Windows Ports

The following ports should be open on the Windows server:

• 3389 - used for RDP

Windows Permissions

Local administrator privileges are needed for the Fabric Studio installation.

Recommended Software

Linux Servers Ports

Open the following ports on the Linux server and make sure they are accessible from Management stations.

Depending on your setup, not all ports are required:

Connectivity

Fabric server and Fabric Studio should have access (permissions) and connectivity (network) to all sources & destinations. Cassandra and Kafka servers should be accessible from Fabric servers’ nodes.
