Again, it's that question about layering, levels, and dependencies which
you choose for your system infrastructure. I sometimes have this problem
where one machine is relying on the uptime of another or the network
in-between. The last thing you want is to include Microsoft technology
somewhere in the middle because, even if both ends run Linux, their
connectivity can be broken due to a Trojan, or a virus (under Windows, of
course). Common examples: Linux box communicates with a Linux mail server,
but needs to go through a Windows firewall, router, or whatever. Another
is a sequential script that involves operation of some function under
Before the SAN over here was changed from Windows to Linux, I suffered on
an almost weekly basis because the Windows server collapsed and make work
virtually impossible. Moreover, it needed a manual reboot ever Monday. How
much IT staff (box booters) did it consume? Probably hundreds of hours.
How much of /my/ time, as its user, has this spend? Probably dozens of
hours, over the course of 1-2 years. I can recall leaving work hours early
just because the server was down permanently. I had to cancel meetings.
Talk about TCO...
Ever since the Linux migration a couple of months ago, not even a quirk. I
can never reclaim these dozens of lost hours, which are worth hundreds of
pounds (for me /alone/). Again, talk about TCO...
The Exchange server that we have in no exception by the way...
