System requirements

This document provides the minimum system requirements for the 8.0 CR3 (and later) release of HCL Connections. Higher maintenance levels, such as fix packs and service packs, may be supported as they become available.

For detailed system requirements for other HCL Connections releases, refer to HCL Connections and Connections Docs System Requirements in the support portal. Detailed system requirements provide complete lists of hardware requirements, supported operating systems, prerequisites and optional supported software, with component-level details and operating system restrictions.

Definition of terms

There are three categories of support for integrated products to HCL Connections. They are "Supported Configuration", "Unsupported Configuration", and "Other Configuration". The definition and support statement for each category follow:

  • Product minimum - The Connections cumulative release (CR) that the new release was certified.

  • Supported Configuration - A combination of HCL Software and other Dependent Products (usually at a specified version, release, fix or specification level) that has been validated by HCL.

  • Unsupported Configuration - A combination of HCL Software and other software packages (at a specified version, release and fix level) that is known to not work with HCL Connections and is therefore not supported.

  • Other Configuration - Includes many configurations of HCL Products and other software exist that are not explicitly listed as "Supported Configurations" or "Unsupported Configurations", but which can reasonably be expected to perform within the accepted bounds of reliability, function, and performance.

For more details, refer to HCL Connections support statement.

Hardware

Disk space

Components Requirements
WebSphere Deployment Manager & Application Server Nodes HCL recommends you have at least 100 GB free disk space on the WebSphere machines under the WebSphere home directory to allow the installation of WebSphere and Connections, and to maintain the retention of configuration files, log files, and diagnostic files. Production deployments will likely require significantly more space to retain log and diagnostic files.

Installation will require:

Temporary:
- 5 GB to download the installation zip file and extract the contents (that is, /tmp//HCL_Connections_8.0_lin.tar & extraction to a temporary directory)

Permanent:
- Approximately 3 GB to install WebSphere (/opt/IBM/WebSphere)
- 2 GB of content will be extracted to the Connections Home directory (/opt/HCL/Connections) during installation on the Deployment Manager
- 2 GB of application binaries and configuration files will be installed under WebSphere (opt/IBM/WebSphere/AppServer)
Connections Home / Local file system Allocate an additional minimum of 20 GB to the local Connections Home file system on each Application Server node for storage of temporary search indexes, cache files and other data (/opt/HCL/Connections).
Connections Shared Content Store This network file storage is mounted on each Application Server and is used to store file content, favicons, SIB Message storage, search indexes and other files shared across all application servers. The size of this storage is greatly dependent on how Connections is utilized. The file system usage should be monitored and expanded as required.

HCL recommends a minimum of 1 TB for production deployments, but customers are encouraged to discuss their requirements with HCL Technical Sales and ensure they plan for future growth.

CPU/Memory

Hardware architecture Requirements
X86 & POWER System WebSphere Application Server node:
- At least 4 CPU and 16 GB of memory is recommended.

Database server:
- At least 4 CPU and 16 GB of memory is recommended. Also refer to the relational database product documentation for additional requirements.
