Mac mini in a data center

Apple dropped the Xserve, pushing the Mac Pro and Mac mini as server alternatives. We need to run many Mac-based applications in our data center, and we've chosen Mac minis.

How do you rack mount a Mac mini? How do you provide IEC C14 or 208V power to a Mac mini?  How do you add an Ethernet management port to a Mac mini? How do you control a Mac mini through a KVM switch?

Let the IPv6 regret storm begin ...

We knew the IPv6 transition was going to be tough for technical reasons.

Now we have the first example of IPv6 security problems that will be tough to fix.

Anti-spam software will have a much harder time blocking spam precisely because of IPv6 3.4 x 10^38 addresses.

I'll bet there are a few more IPv6 security problems waiting to be found.

Let's set arbitrary deadlines to switch to IPv6 before we find or fix these problems!

Oh wait, we've already done that.
