Tis an Apollo 8k node. Each dimm has a metal heatspreader, Heatpipecooler on top of the procs coming out to that cold plate.
HP Apollo is one of a various number of things:what is HP Apollo?
Looks great..I grabbed a few pictures from work of our new datacenter, figured you guys might be interested. I was very involved in the entire project, from the early design through construction and migrating our equipment around, and am still down there as needed when issues can't be fixed remotely; and it was the most enjoyable project I've ever worked on - learned a TON of stuff doing it (mostly related to HVAC/cooling, smoke-detection/fire-supression, and other non-IT topics). It is a small datacenter by modern standards (36 racks, and if UPS/cooling is expanded to capacity capable of 225kW of load), but state of the art with structured cabling, in-row cooling (designed to grow into hot-aisle containment when required), modular power distribution, fancy nitrogen-based fire-supression, etc. If anyone has questions about anything I'm happy to answer them. That out of the way - here are the pics.
