SMTP load balancing with F5 LTM

In my previous blog I explained how to configure the F5 LTM for use with Exchange 2010 CAS servers. To do this properly it is recommended to use a template (iApp) because of the amount of work (and thus complexity).

Load balancing SMTP is much easier. The only things that need to be configured are:

  • Service Monitor for monitoring the SMTP service on the Exchange 2010 Hub Transport Servers;
  • A Pool containing the Exchange 2010 Hub Transport servers;
  • A VIP for the SMTP service with a listener on the public network.

To create a new Service Monitor select the Local Traffic and click the + symbol next to monitors. Give the new monitor a name like SMTP_Monitor and if needed adjust the service health monitoring interval. Continue reading SMTP load balancing with F5 LTM

Load Balancing Exchange 2010 with F5 LTM

In a earlier blogpost on load balancing Exchange 2010 I explained how to achieve this with a Kemp Loadmaster. In this blogpost I’d like to demonstrate how to configure this with an F5 Local Traffic Manager (LTM). This is actually part I of what I’ve demo’ d in the MEC 2012.

The configuration looks like this. There are two multi-role servers configured with a Database Availability Group (DAG). There’s a File Share Witness (FSW) configured on server FS01. The F5 itself is installed in a two arm configuration, so the VIP for the clients is on a different subnet then the Exchange Server.
