Fabric & TDM 7.xx Hardware Requirements for Development and QA Environments

PostgreSQL

• PostgreSQL is generally required for TDM projects only.

• K2view supports PostgreSQL version 9.6 & 13.

• PostgreSQL requires 100G storage.

• PostgreSQL can be deployed in one of these ways:

  • On a VM (use latest CentOS/Redhat Operating System with latest patches), or
  • As a service.

  For cloud deployments:

• If using AWS: EC2: a1.2xlarge, m5.xlarge

• If using Azure VM: A8v2

• If using GCP: e2-standard-4

  For example, if you are implementing PostgreSQL as a PaaS, you can use the following:

  • For AWS: RDS PostgreSQL
  • For GCP: Cloud SQL PostgreSQL see here for more about PostgreSQL

Fabric/Cassandra/Kafka Linux Execution Server Specifications

Hardware Requirements (for each Linux server):

• OS: latest CentOS/Redhat Operating System with latest patches Note: Cassandra requiers python 2.7
• CPU: 4 Cores/vCPUs (Modern Xeon Processor)
• RAM: 12GB
• Storage: The preferred storage is attached local SSD’s in non-RAID configuration.
  When SAN must be used, it must be flash and in RAID-0. NAS are not certified

The FS volumes required are as follows:

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

• Volume of 200G /opt/apps/cassandra/

• Volume of 50G /opt/apps/kafka/

  For Cloud installation:

  • If using AWS: EC2: m5.2xlarge
  • If using Azure: Standard_DS14_v2
  • If using GCP: e2-standard-8

Linux Server Setup

Follow these steps to setup a Linux Server:

1. NTP/chrony installed and configured
2. Add a user ‘fabric' with group 'fabric'
3. Add Admin permissions to the fabric user.
4. Provide read/write access to /opt/apps/fabric
5. Remote access option (SSH) enabled to user fabric.
6. Add a user ‘cassandra' with group ‘fabric’
7. Provide read/write access to /opt/apps/cassandra
8. Remote access option (SSH) enabled to user cassandra.
9. Add a user ‘kafka with group ‘fabric’
10. Provide read/write access to /opt/apps/kafka
11. Remote access option (SSH) enabled to user kafka.

Run the following as ROOT:

echo "root  soft   nproc   unlimited"  >> /etc/security/limits.conf
echo "cassandra - nofile 100000" >>  /etc/security/limits.conf
echo "cassandra - nproc 50000" >> /etc/security/limits.conf
echo "fabric - nofile  100000" >> /etc/security/limits.conf
echo "fabric - nproc  50000" >> /etc/security/limits.conf
echo "kafka hard  nofile 100000" >> /etc/security/limits.conf
echo "kafka soft  nofile 100000" >> /etc/security/limits.conf
echo "kafka - nproc  50000" >> /etc/security/limits.conf
echo "kafka - nproc  50000" >> /etc/security/limits.conf
## update /etc/sysctl.conf  ##
echo "## Added by  K2view - GabiO" >> /etc/sysctl.conf
echo  "vm.max_map_count = 1048575" >> /etc/sysctl.conf
echo "fs.file-max =  1000000" >> /etc/sysctl.conf

Linux Ports

Open the following ports on the LINUX server, and make sure they are accessible from outside the server:
