Right now I am working on a VMware / Security project that will allow us to partially virtualize our physical Anti-Spam and Management Servers. On an average, we process 1.2 million of incoming e-mails per day through 1 Anti-Spam Server that is behind our firewalls. The new plan is to have 2 Anti-Spam Servers to handle the load plus 1 Management Server.
In the new world, both Anti-Spam Servers will be active and share 50% of the load each. One of them is going to be a Virtual Machine and the second one a physical server; the Management Server will also be virtualized.
If one of the Anti-Spam Servers fail, the second server will process all the e-mail and if the management server fails we will restore a copy of the Virtual Machine (some downtime here is acceptable since incoming e-mail will continue to be processed).
The product selected for the Anti-Spam Servers was Symantec Mail Security for SMTP and VMware Infrastructure Enterprise Edition for the Virtualization platform. In a couple of weeks the project will be fully implemented, so I am going to update this post with the results of the migration and a Visio diagram of the implementation.
