That product you linked to isn't all that bad, provided that you run with a front plate to actually block off the rest of the cold isle and force the air to flow to the hot isle. But that doesn't seem to be included anywhere. So I agree that it's wishful thinking.
The reality of the power budget makes the most sense really. There's no point in cramming extra units in if you're going to have to rewire for them. Systems engineering!
- skuhn 12y agoH-Squared's product isn't terrible by any means, but I see it as phase 1 of at least a 2 or 3 phase solution. If you were running one shelf of Pros in a rack, it wouldn't matter much -- but at 10 racks of 88 Pros each, you'll run into cooling issues unless you put more work into it. On the topic of density: our chassis was originally specced to support 6 units rather than 4. I vetoed that because it would require a second top-of-rack switch, and would have been too power dense for our current site design. 44 turned out to be the magic number this time around. The design is also flexible enough that if the specification changes dramatically in future Mac Pros, we can tweak as necessary to achieve ideal density.
