System Requirements

This document contains information about hardware and software requirements for HCL™ Accelerate.

Minimum system requirements for proof of concept environment

Table 1. Minimum system requirements for Proof of concept (POC)
Resource Requirement
Platform Docker Compose
Number of Platform Nodes N/A
Operating System See the Docker platform documentation for supported operating systems
Processor 4 CPU Cores
Memory 12 GB RAM
Storage
  • 20 GB for MongoDB storage with continued growth over extended usage (see figure below for storage guidelines)
  • 3 GB for RabbitMQ and all HCL™ Accelerate Docker containers
  • 4 GB during the installation process
Network Gigabit (1000) Ethernet with low-latency to the database
Additional information
  • 3 GB for RabbitMQ and all HCL™ Accelerate Docker containers is a permanent requirement for running all services.
  • 4 GB is an temporary requirement for the installation process. After installation, 4 GB is available for other usages.

Minimum system requirements for production environment

Table 2. Minimum system requirements for production environment
Resource Requirement
Platform Kubernetes, OpenShift
Number of Platform Nodes 3
Operating System See your Docker platform documentation for supported operating systems
Processor 4 CPU Cores
Memory 12 GB of RAM
Storage
  • 20 GB for MongoDB storage with continued growth over extended usage (see figure below for storage guidelines)
  • 3 GB for RabbitMQ and all HCL™ Accelerate Docker containers
  • 4 GB during the installation process
Network Gigabit (1000) Ethernet with low-latency to the database
Additional information
  • 3 GB for RabbitMQ and all HCL™ Accelerate Docker containers is a permanent requirement for running all services.
  • 4 GB is an temporary requirement for the installation process. After installation, 4 GB is available for other usages.
Note: MongoDB is not installed by default with the product installation for Kubernetes and OpenShift platforms. You are expected to install it separately. It is highly recommended to allocate one node for MongoDB and three nodes are for the product installation for better performance and stability of the application.

MongoDB requirements

MongoDB requirements

Unlike Docker Compose, the MongoDB is not installed by default and you are expected to install it separately, configure, and maintain the database. As a guideline, use the following specifications:
  • 2 CPU Cores
  • 8 GB RAM minimum (16 GB recommended)
  • 20 GB storage minimum (50 GB recommended)
Note: MongoDB replica sets are supported if configured by the customer. Additional details are found here.

The figure below provides storage guidelines over time and contributors to total size.

Figure 1. Storage guidelines
storage guidelines over time graph and contributors to total size pie chart
For the above graph, estimates are calculated using real production data and with the following assumptions:
  • Each onboarded application has at least one associated value stream.
  • Over 300 issues are created and imported per year with associated Pull requests (PRs) and commits.
  • Over 20 builds and deployments are captured per application per day.
  • Five quality metrics are captured per build with examples including functional test results, code coverage, vulnerability scans, and so forth.
The following table details growth estimates over time based on number of apps per year.
Table 3. Growth estimates
Number of apps per year Day 1 (GB) Year 1 (GB) Year 2 (GB) Year 3 (GB)
1 0.5 4 8 13
5 2 10 17 25
10 5 16 28 41
25 12 37 62 88
The following table details estimates for environments based on number of apps.

Environment Number of apps Size (GB)
POC 1-3 20
Pilot 5-10 30
Typical onboarding 20-30 70
