Fabric Minimum System Requirements for Production 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 a TDM library and a PostgreSQL installation.

Fabric Execution Servers - Node Specifications

The Fabric server installation is a Linux-based solution. Use dedicated servers for Fabric instances. 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.

For docker installation, the latest Docker Engine and Docker Compose installations are recommended.

Hardware Requirements:

Examples of Cloud-supported Instance Types:

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

• Volume of 50GB/opt/apps/fabric/ - will be used also as the home directory for a Fabric user.
• Volume of 100GB /opt/apps/fabric/storage

Note:

• The FS must provide IOPS of at least 30K read and 10K write on each node.
• The above volume values should be modified in accordance with the project scope and data retention requirements.

Kafka Server Node Specifications

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

Minimum System Configuration for Each Kafka Node Server

Software Requirements:

Operating system:

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

Hardware Requirements:

Examples of Cloud-supported Instance Types:

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

Volume of 150GB /opt/apps/kafka/ - will be used also as the home directory for a Kafka user.

Note:

• The FS must provide IOPS of at least 30K read and 10K write on each node.
• The above volume values should be modified in accordance with the project scope and data retention requirements.

Cassandra Server Node Specifications

The Cassandra server installation is a Linux-based solution. Use dedicated servers for Cassandra instances. 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 the latest patches (for example: CentOS, Oracle Linux).
• Ubuntu Server, version 18.04 or higher, with the 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:

Examples of Cloud-supported Instance Types:

For Cloud-based VM, NVMe storage type is preferred for a high performance.

AWS

Azure

GCP

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

• Volume of 50GB /opt/apps/cassandra/
• Volume of 450GB /opt/apps/cassandra/storage

Note:

• The FS must provide IOPS of at least 30K read and 10K write on each node.
• The above volume values should be modified in accordance with the project scope and data retention requirements.

PostgreSQL Server Node Specifications

• PostgreSQL is required for TDM projects only.
• PostgreSQL can be deployed in one of the following two ways:
  • On-premises as a virtual or a physical machine.
  • As a cloud service (SaaS)

Suggested System Configuration for a PostgreSQL Server

Software Requirements:

Operating system:

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

Hardware Requirements:

Examples 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 for configuring, managing and controlling 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 an 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 Server Ports

Open the following ports on the Linux server and ensure 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 and destinations. Cassandra and Kafka servers should be accessible from Fabric servers’ nodes.
