1 Introduction

Microsoft SharePoint is a web platform that provides many capabilities such as:

• Document management
• Version control
• File sharing
• Collaboration
• Social networking
• Enterprise search
• Business intelligence
• Workflow automation
• Website creation

A SharePoint Server Farm can include application servers and Web Front End (WFE) servers. The WFE server is used to handle requests from clients. If the WFE server is receiving a lot of requests, it may be necessary to build multiple WFE servers and distribute the load amongst them. To provide resiliency and high performance, these WFEs should be load balanced.

The Office Web Apps (OWA) servers can also be managed and/or load balanced by using the LoadMaster. The SharePoint template and steps in this document provide options for both.

1.1 Intended Audience

This document is intended for use by anyone who is interested in learning about deploying a Kemp LoadMaster with SharePoint.

1.2 Document Purpose

This deployment guide provides instructions on how to configure the Kemp LoadMaster to load balance SharePoint using Kemp LoadMaster application templates. This guide should only be used as a reference for the load balancing configuration of SharePoint services because each environment is unique and may have different requirements. This guide outlines the load balancing configuration using the default SharePoint ports using Kemp LoadMaster application templates, but unique ports can also be leveraged based on the environment.

This guide also outlines the configuration of Virtual Services using Layer 7. Some environments may have the ability to leverage Layer 4, which can improve performance. Contact Kemp Support for any questions regarding configuration options.

1.3 Prerequisites

It is assumed that if you are offloading SSL, an SSL certificate and key is already obtained and installed on the LoadMaster. For help with SSL certificates, refer to the SSL Accelerated Services, Feature Description on the Kemp Documentation page. It is also assumed that a working SharePoint environment is installed.

2 Template

Kemp has developed a template containing our recommended settings for this workload. You can install this template to help create Virtual Services (VSs) because it automatically populates the settings. You can use the template to easily create the required VSs with the recommended settings. For some workloads, additional manual steps may be required such as assigning a certificate or applying port following. These steps are covered in the document, if needed.

You can remove templates after use and this will not affect deployed services. If needed, you can make changes to any of the VS settings after using the template.

Download released templates from the following page: LoadMaster Templates.

For more information and steps on how to import and use templates, refer to the Virtual Services and Templates, Feature Description on the Kemp Documentation page.

3 LoadMaster Global Settings

Before setting up the Virtual Services, the following global settings should be configured to support the workload.

3.1 Layer 4 Considerations before Deployment

For this application, if you are using an L4 service, it is automatically transparent. When using transparency, the following should be considered:

If clients are on the same subnet as the Real Server, returning traffic to the LoadMaster is instead sent to the client. This is asymmetric routing and causes the client to drop the connection because it is expecting it from the LoadMaster, not the Real Server. The diagram below shows the flow of traffic when this rule is not followed.

If the Real Servers' default gateway is not set to be the LoadMaster's interface (the shared IP if the LoadMasters are in HA), traffic returning to the LoadMaster is instead sent to the gateway. This is asymmetric routing and causes the connection to drop because the connection should be sent from the LoadMaster, not the Real Server. The diagram below shows the flow of traffic when this rule is not followed.

3.2 Enable Subnet Originating Requests Globally

It is best practice to enable the Subnet Originating Requests option globally.

In a one-armed setup (where the Virtual Service and Real Servers are on the same network/subnet) Subnet Originating Requests is usually not needed. However, enabling Subnet Originating Requests should not affect the routing in a one-armed setup.

In a two-armed setup where the Virtual Service is on network/subnet A, for example, and the Real Servers are on network B, Subnet Originating Requests should be enabled on LoadMasters with firmware version 7.1-16 and above.

When Subnet Originating Requests is enabled, the Real Server sees traffic originating from 10.20.20.21 (LoadMaster eth1 address) and responds correctly in most scenarios.

With Subnet Originating Requests disabled, the Real Server sees traffic originating from 10.0.0.15 (LoadMaster Virtual Service address on eth0) and responds to eth0 which could cause asymmetric routing.

When Subnet Originating Requests is enabled globally, it is automatically enabled on all Virtual Services. If the Subnet Originating Requests option is disabled globally, you can choose whether to enable Subnet Originating Requests on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

1. In the main menu of the LoadMaster User Interface (UI), go to System Configuration > Miscellaneous Options > Network Options.

2. Select the Subnet Originating Requests check box.

3.3 Enable Check Persist Globally

It is recommended that you change the Always Check Persist option to Yes - Accept Changes. Use the following steps:

1. Go to System Configuration > Miscellaneous Options > L7 Configuration.

2. Click the Always Check Persist drop-down arrow and select Yes - Accept Changes.

4 Configure the LoadMaster for SharePoint

To configure the LoadMaster for SharePoint, you must set up Virtual Services:

• Some are for the Central Administration site, which is used to administer the SharePoint configuration overall. When you deploy the first SharePoint server, the management site is created. Further production sites can be created as needed.
• The other Virtual Services are for the User Portal Site. This is for access to MySites and the rest of the SharePoint infrastructure.

This guide contains a section on creating a Virtual Service in the WUI using a template. To configure the Virtual Services using the Application Programming Interface (API), refer to the RESTful API on the Kemp documentation page.

The table in each section outlines the API settings and values. You can use this information when using the Kemp LoadMaster API and automation tools.

Using a template automatically populates the settings in the Virtual Services. This is quicker and easier than manually configuring each Virtual Service. If needed, changes can be made to any of the Virtual Service settings after using the template. For more information on the SharePoint templates, refer to the Template section.

It may be possible to have a single Virtual Service for both that has extra ports, but you might want different settings on the different Virtual Services, or you might want one Virtual Service to be only accessible internally, for example.

The sections below give instructions on how to set up Virtual Services for Microsoft SharePoint. Refer to the relevant sections for step-by-step instructions on configuring the Virtual Services, depending on your environment. The settings contained in this document are recommended by Kemp. However, your specific configuration may require different settings.

For more information on each of the fields, refer to the Web User Interface (WUI), Configuration Guide on the Kemp Documentation page.

4.1 Two-Armed Configurations

If you have a two-armed configuration with SSL offloading, you may need to enable subnet originating requests. This can either be done on a per-Virtual Service basis (Subnet Originating Requests field in Standard Options in the Virtual Service modify screen), or on a global basis (System Configuration > Miscellaneous Options > Network Options > Subnet Originating Requests).

It is recommended that the Subnet Originating Requests option is enabled on a per-Virtual Service basis.
While a one-armed configuration is not common, it is supported. For security best practice, you should separate the network that clients will connect to from the network that the Real Servers are on.
