Minimum Requirements for Setting up MEX

Minimum Requirements for Setting up MEX

When scoping for a MEX implementation, there are two initial things to consider in regards to the setup of the software on your server, these are:

  • The SQL Server
  • The IIS Server

In general, you should look at the maximum number of concurrent users. The SQL part of MEX tends to be fairly minimal (we supply you with SQL Express with the installation), so for most cases the main thing to optimise would be the IIS. 

As a benchmark we usually say one processor core per 5 concurrent users, concurrent users being limited by the number of MEX user licenses that you purchase.

You can split the SQL and IIS onto different servers as long as they are on the same network segment, as MEX tends to be quite chatty between the SQL and IIS processes. In this case, there would be no reason not to put them onto the same box.

In general, the minimum requirements for a server is:

  Minimum Requirement

Operating System:

Windows Server 2012 or later


A quad-core CPU


8GB of RAM or more

SQL Version:

SQL 2012 or later

.NET Version:

4.5.2 or higher

Storage for SQL Database:

Reserve a minimum of 10GB for your database files. As MEX is installed with the SQL 2012 Express version that is limited to a maximum database file of 10GB. For larger applications of MEX, scale up your database storage space accordingly.

Document Storage:

MEX recommends a minimum of 10GB. Depending on your usage, if you and your users are going to be adding documents to Assets and work orders on a regular basis. You need to ensure that you have ample space on your server that’s hosts MEX as all Documents are stored within the MEXData website directory. 

Network Bandwidth:

Network speed between the MEX client and the IIS server should be 256kB/sec minimum (1MB/sec recommended). If the SQL server and IIS server are to be on different physical servers, they should be on the same LAN segment

Do note that MEX V15 uses .eml files, which aren’t compatible with anything earlier than Outlook 2010 (or at least not easily, there are some fixes Microsoft have for Outlook 2007, which work with varying success).
