Earlier this week, Sun Microsystems announced that its Project Blackbox was now a commercially shipping product. I have to confess that when they first told me about this effort I saw it as a nice showcase innovation — something they could use to demonstrate how densely racks could be configured and how energy efficient their products were. They could drive it from city to city for in-person demonstrations. Nice marketing idea. But I didn’t see the practicality to real enterprise data centers. Who’d be willing to buy a container and park it outside their data center? Yeah, that’s secure.
