not all servers are equal

I know a site using a linux server built by us from commodity parts running all their business
critical database applications.

The same customer has 2 windows servers specifically for email, a windows sftp server, 3 file
servers, a datawhorehouse server, a vpn server and a couple of backup servers. There are
several other boxes whose purpose we have never worked out including a strange firewall box
that only has a single network cable plugged in. Most of this is duplicated across to a second
site.

Adding to that a couple of print servers and all the desktops gives you a pretty impressive
windows count. But its the linux box that is on 24x7, its the linux box that earns the money,
and its the linux box that has proper DR redundant backups off site that would be up 5 minutes
after the event.

Of course I would say that though, I think our data is important, that's why we chose Linux!
