West km Server Configuration

The West km server(s) must be dedicated solely to West km resources and should not be shared with other applications or services. All servers must be up to date with all of the latest available Operating System patches.

The following items are the client's responsibility to provide.

Hardware - 64 bit
Processor:	Quad Core Xeon 2.0 GHz or faster
Memory:	16 GB or higher

Operating System

Microsoft Windows Server 2008 R2 (64-bit), Windows Server 2012 R2 (64-bit), or 2016 R2 (64-bit) with the following components:

Internet Information Services (IIS) 7, 7.5 (2008), 8.5 (2012), 10 (2016)
Microsoft .NET Framework 4.6, 64-bit (installs with West km)
Java Runtime Environment 1.8, 64-bit (installs with West km)
Microsoft F# Runtime 4.0, 64-bit (installs with West km)
Powershell 3 or higher
Windows Update Windows8.1-KB2999226-x64.msu

Note: A secondary drive separate from the Operating System drive is requested for the installation of the West km software suite.

System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing must be disabled.

IIS Components

Web Server
ASP.NET 3.5
.NET Framework 3.5
Windows Authentication
WebDAV Authoring needs to uninstalled

Database Management

Microsoft SQL Server Standard or Enterprise Edition: 2017, 2016, 2014, 2012, and 2008 R2 (64-bit)

Code Page: 1252 required
Sort Order: "Dictionary order, case-insensitive" required
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)

If Enable Autogrowth is turned on, our recommendation for the km database is to have File Growth set to 5% and Maximum File size to 80% of available space on the drive

Note: Your SQL password cannot contain special characters "&" or "=" or “#”

Browser with Internet Access

Microsoft Edge current version

Internet Explorer 11
Firefox current version
Chrome current version

Note: It is highly recommended that SSL (https) is used on the West km server to avoid allowing mixed content or unsafe scripts to run in the browser when WestlawNext integration is being used. This requires that a security certificate be installed on the West km delivery server.

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

All your West km servers must allow HTTP and port 80 access for outbound TCP communications through your firewall (specific addresses are available upon request). 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. Proxy authentication is not supported.

Network Configuration

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

Antivirus Configuration

Configuration of your server in accordance with Microsoft knowledge base article 312592.

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.

Capacity Planning

A one-server configuration can usually be used for an environment running the following:

West km for Litigation for one site
100 or fewer users
250,000 or fewer indexed documents

A multi-server configuration is needed for a larger West km for Litigation environment or for a West km for Transactions environment.

Upon request, Thomson Reuters will work with you to appropriately size and configure servers and to provide scaling recommendations for environments with more than 750 users or more than 750,000 indexed documents.

For the best performance, do not process more than 1 million documents through West km. Environments are not supported beyond 1.5 million indexed documents (i.e., the number of documents indexed before the citations only filter is applied).

For the best performance, do not create vetting groups in excess of 500,000 documents.

Note: The server recommendations assume that indexing will be scheduled based upon West km recommendations, which result in server resources being available for content delivery.

Users/Documents		Recommended Servers
*West km for Litigation Only*
	1–100 concurrent users; 1–250,000 documents	Server 1 Delivery, indexer, database, HTML repository/search 16 GB RAM Diagram of 1-server configuration
*West km for Litigation or West km for Transactions*
	1–100 concurrent users; 1–500,000 documents	Server 1 Delivery, secondary indexer, database 16 GB RAM Server 2 Primary indexer, HTML repository/search 16 GB RAM Diagram of 2-server configuration
	101–750 concurrent users; 500,000–750,000 documents	Server 1 Delivery, secondary indexer 16 GB RAM Server 2 HTML repository/search, primary indexer 16 GB RAM Server 3 Database 16 GB RAM Diagram of 3-server configuration
*West km Integration Services* At minimum, West km Integration Services requires a 1-server configuration.

Configuration of Required Software for Multi-Server Environments
If you are distributing the West km server components among several machines, the following software is required on each server component prior to West km software installation.

Software	Delivery	Database	Indexing	HTML Repository/Search
Windows Server	X	X	X	X
Internet Information Server (IIS)	X		X	X
ASP.NET is enabled	X		X	X
Microsoft SQL Server		X
Client for DMS— eDOCS DM (API connection)	X		X	X

Disk Space Calculations

Documents in West km for Litigation

Number of work product documents (in native format) to be indexed = D
Average size of document = S
Total size of documents to be indexed = T = D * S
Approximate disk space required on the West km server = T * 3

Example:
Your organization has 100,000 work product documents, averaging 60 KB per document.

D = 100,000
S = 60 KB
T = 100,000 * 60 KB = 6 GB

Disk space required on the West km server = 6 GB * 3 = 18 GB

Calculations should also take into account these considerations:

Growth: the number of years in the server cycle and the approximate number of new documents being added to West km per year.
Backup/recovery: the ability to perform backup and recover procedures on a server within a specified period of time.

Documents in West km for Transactions

Number of work product documents (in native format) to be indexed = D
Average size of document = S
Total size of documents to be indexed = T = D * S
Approximate disk space required on the West km server = T * 9

Example:
Your organization has 100,000 work product documents, averaging 60 KB per document.

D = 100,000
S = 60 KB
T = 100,000 * 60 KB = 6 GB

Disk space required on the West km server = 6 GB * 9 = 54 GB

Calculations should also take into account these considerations:

Growth: the number of years in the server cycle and the approximate number of new documents being added to West km per year.
Backup/recovery: the ability to perform backup and recover procedures on a server within a specified period of time.
