BTW, the two servers are virtual machines in one and the same physical box.
What's the point of that? (Genuine question.)
One server here, one across town, or even two separate boxes in a single room -- sure. But in the same box? If the the box is on fire, now you're out both your main and your backup server.
I must be missing something; what is it?
I've never been a fan of doing that, but I've recently been seeing it at a lot of clients. They have 2 older machines each running its own app. They get a new honking big box with enough HP to run both apps and they create 2 VMs one for each app.
Yes, one point is to consolidate using virtualization. It is done in small environments and in really large ones. A very different thing is to run a main and a backup mail server on the same virtualization host as 2 VMs. Alone the fact to build up a setup with a backup mail server is nowadays to 99% a design flaw and non-optimal.
