SunGard eSchool

1 Introduction

SunGard eSchool is a student information system that manages student information throughout their entire educational career.

The KEMP LoadMaster is used to load balance the SunGard eSchool Server workload. The LoadMaster offers advanced Layer 4 and Layer 7 server load balancing, SSL Acceleration and a multitude of other advanced Application Delivery Controller (ADC) features. The LoadMaster intelligently and efficiently distributes user traffic among the application servers so that users get the best experience possible. 

1.1 Document Purpose

This deployment guide provides instructions on how to configure the KEMP LoadMaster to load balance the SunGard eSchool Server.

3 Configure the LoadMaster

The deployed SunGard environment determines which of the following setups is used.

3.1 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 LoadMaster will route traffic so that the Real Server will see traffic arriving from the LoadMaster interface that is in that network/subnet not the Virtual Service address.

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 or not 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 Web User Interface (WUI), go to System Configuration > Miscellaneous Options > Network Options.

2. Tick the Subnet Originating Requests check box.

3.2 Create the SunGard eSchool Virtual Services

The following sections describe the recommended settings for the SunGard eSchool Virtual Services.

Create a SunGard eSchool HTTPS Redirect Virtual Service

Clicking the Add HTTP Redirector button automatically creates a port 80 redirect Virtual Service. This is optional, but the purpose of this Virtual Service is to redirect any clients who have connected using HTTP to the HTTPS Virtual Service. KEMP also recommends changing the Persistence Mode and Real Server Check Method to None.
