West km Express System Requirements (Version 6.6)

Below are the system requirements for West km Express version 6.6. These requirements apply to West km Express for Litigation.

All requirements are current as of the publication of this document. Please confirm the specific requirements with your West km technical consultant before software installation.

West km Server Configuration

Per the software agreement, only a single instance (single-server) of West km Express is supported. Multi-server configurations are not supported. For the best performance, limit the document population to 250,000.

The West km Express server should not be shared with other applications or services. A new or existing/repurposed file server can be used for West km Express, as long as no other applications or database software is installed and running (e.g., e-mail, case or document management, or other database software). West km Express is not supported on a domain controller.

Hardware Requirements

  • Hardware: 64-bit
    • Processor: 8-Core Xeon 2.5 GHz or faster
    • Memory: 32 GB or higher

Statement of Compatibility for Virtual Environments

Support is provided for West km running on a virtual environment (e.g., VMware) without initially requiring reproduction of West km issues on native hardware. The virtual machines must meet minimum requirements.

If your West km technical consultant suspects that the virtualization layer is the root cause of an issue, you may be required to contact the appropriate support provider for your virtual environment to resolve the issue.

West km functional issues are rare under virtual environments, but performance and capacity issues are more common. Performance issues that deviate from internal benchmarks will require you to disable other systems that are competing for physical system resources and may possibly require you to remove West km from the virtual environment altogether.

Remote Access

Provide Thomson Reuters with VPN-based remote access to the West km server for installation and on-going support. Examples of VPN-based methods include the following:

  • Terminal Services
  • Cisco VPN
  • Citrix
  • Direct Windows Remote Desktop

Operating System (Server)

The following supported operating systems must be installed prior to installing West km:

  • Microsoft Windows Server 2019 (GUI, 64-bit)
  • Microsoft Windows Server 2022 (GUI, 64-bit)

Additionally, PowerShell 5.1 or higher must be installed.

IIS Components

The following IIS components are required:

  • Web Server
  • ASP.NET 4.8
  • Windows Authentication

Note: WebDAV Authoring needs to be uninstalled.

Note: An SSL certificate is required within IIS on the West km server to support integration between West km and Westlaw.

Installed Components with West km

The following components are installed with West km:

  • Microsoft .NET Framework 4.8, 64-bit
  • Corretto 8 JRE
  • Microsoft F# Runtime 4.0, 64-bit
  • Chocolatey (KM Installation)

Additional Notes

  • Secondary Drive Requirement: A secondary drive separate from the Operating System drive is required for the installation of the West km software suite to accommodate Elasticsearch data, SQL, and logs.
  • System Cryptography: The setting "Use FIPS compliant algorithms for encryption, hashing, and signing" must be disabled.
  • Remote Accessibility (WinRM): The WinRM service needs to be started and set to automatic startup. Firewall rules and security settings must allow for WinRM traffic to each of the West km servers.

Database Management

West km can be installed with SQL Express 2022 by default (see SQL Server Requirements below). Alternatively, West km can use an existing SQL Server instance with the following configurations:

  • Microsoft SQL Server Standard or Enterprise Edition: 2022, 2019, 2017, 2016 (64-bit)
  • AUTO_CREATE_STATISTICS set to ON for the West km databases
  • Static port configuration required
  • Cannot be installed on a domain controller
  • High Availability/Always On must be turned off during installation (can be turned on post-installation)

Note: SQL Account recommended and password cannot contain special characters: ( ) - & @ * $ | % ~ = # < >

SQL Server Requirements

  • SQL Server Express can be installed as part of installation or an existing SQL environment can be used.
  • SQL Account must have DBOwner rights to km / kmRID databases.

Multi Domain Considerations

West km supports a multiple domain environment. For Integrated Windows Authentication (IWA), an LDAP or GC connection string and a network account with a non-expiring password associated with each domain will need to be provided.

Security and Access Considerations

Note: A Supported Browser with Internet Access.

Note: Native XMLHTTP support must be enabled. To enable this feature, click Tools and then click Internet Options. Click the Advanced tab and scroll to the Security section. Ensure that the Enable XMLHTTP Support option is checked.

Firewall and Proxy Exceptions

Note: Proxy authentication is not supported.

All West km servers must allow HTTP and port 80 or HTTPS and port 443 access for outbound TCP communications through your firewall. If you have a proxy server and utilize authentication, the West km server should be listed as an exception so it bypasses the proxy server.

West km will need the ability to invoke web requests to the following URLs through PowerShell for the installation:

  • onepassservices.westlaw.com
  • km.westlaw.com
  • chocolatey.org
  • microsoft.com
  • download.microsoft.com
  • corretto.aws
  • code.jquery.com
  • downloads.westkm.com
  • powershellgallery.com

Ports and URLs

The ports used by West km are listed below. You may need to change port settings if a conflict exists with another service already using that port or if a firewall blocks a port.

Database Management Server Ports

  • 1433 Microsoft SQL Server’s default port

Note: Microsoft SQL Server must be configured to use a static port.

West km Ports
