NotifyLink Enterprise Server (NLES) requires three components to function:
•SQL Database Component
•Web/HTTP Server Component
•Messaging Server Component
The information in this section outlines the system hardware recommendations/guidelines for an NLES system. It is important to note that minimum requirements will vary depending on the factors which make up your environment, such as:
1. Whether you plan to have a single or multiple NLES server configuration.
2. The email and PIM usage of the users.
3. The number of ActiveSync messaging based devices versus NotifyLink messaging devices.
4. The type of collaboration suite software you are using.
5. Drive speed.
6. Log and Database size.
An additional factor that can limit the performance of NLES is the use of Microsoft SQL Express. SQL Express will allow a database with a maximum size of 4GB. ActiveSync devices retain a larger amount of data in the logs and databases, which can result in a 4GB database being filled quite quickly. We recommend that users in this situation install a full version of Microsoft SQL for the NLES SQL component.
Before installing NLES you must have the following:
Windows Server Operating System Versions:
2008 R2 SP1, 2008 with SP2, 2003 R2 x64, or 2003
Or
VMWare 3.0 or VMWare vSphere 4.0/4.1 (recommended)
Microsoft SQL Server:
2008 R2, 2008 R2 with SP1, 2008 with SP3, 2008 with SP2, 2008 with SP1, or 2005 with SP3
Web Servers:
Microsoft Internet Information Server (IIS): English Versions 7.5, 7.0, or 6.0
OR
Apache: Version 2.2.x
