Here is a look at the liquid-cooled versus the air-cooled server. QCT Liquid Cooling Solution Intel Innovation 2022 17 This is the liquid-cooled server connected to the CDU. QCT Liquid Cooling Solution Intel Innovation 2022 12
This only has two servers, so we see additional hoses between the hot and cold sides of the manifold. On the side of the rack, there is a rack manifold. QCT Liquid Cooling Solution Intel Innovation 2022 16 Also, the entire rack is being monitored via BMCs so one can see the performance of not just the servers, but the entire liquid cooling solution down to the CDU and pumps at the bottom of the unit. Starting from the top of the rack, we have a small PDU. QCT Liquid Cooling Solution Intel Innovation 2022 18 Here is the bottom of the heat exchanger. QCT Liquid Cooling Solution Intel Innovation 2022 8 That requires flexible hoses at the top and bottom of the rack. QCT Liquid Cooling Solution Intel Innovation 2022 10 Opening the door, we see a full rear door heat exchanger setup. QCT Liquid Cooling Solution Intel Innovation 2022 7 That is perhaps the biggest driver of efficiency improvement in this rack. While the fans themselves use more power than a typical server chassis fan, they also use less power for equivalent cooling to smaller chassis fans. These fans are also swappable via cages that disengage from the rear. QCT Liquid Cooling Solution Intel Innovation 2022 6 QCT Liquid Cooling Solution Intel Innovation 2022 5 The CDU has a filter (left) along with two pumps (center and right.) These are hot-swappable designs. That may seem like a lot, but it is less than the fans in a full rack of servers. QCT Liquid Cooling Solution Intel Innovation 2022 4īelow the servers at the bottom of the rack is a redundant 3kW PSU to drive all of the cooling. We see a QCT D54Q-2U liquid and air cooled server stacked in the rack. In the middle is perhaps the most important part. QCT Liquid Cooling Solution Intel Innovation 2022 2 Here is a look at the rack that we saw on the Intel Innovation exhibition floor. QCT Liquid Cooled Rack Intel Sapphire Rapids Bake-Off We covered this briefly in our Tour of the QCT Intel Sapphire Rapids System Overload Booth, but we wanted to go into details a bit more in a separate piece.
One of the coolest demos at Intel Innovation 2022 was the QCT Liquid Cooled Rack demo.
