IBM isn’t the one one.
“We’ve been doing liquid cooling since 2012 on our supercomputers,” says Scott Tease, vice chairman and basic supervisor of AI and high-performance computing at Lenovo’s infrastructure options group. “And we’ve been enhancing it ever since—we’re now on the sixth era of that know-how.”
And the liquid Lenovo makes use of in its Neptune liquid cooling answer is heat water. Or, extra exactly, sizzling water: 45 levels Celsius. And when the water leaves the servers, it’s even hotter, Tease says. “I don’t have to sit back that water, even when I’m in a sizzling local weather,” he says. Even at excessive temperatures, the water nonetheless gives sufficient cooling to the chips that it has actual worth.
“Usually, an information middle will use evaporation to sit back water down,” Tease provides. “Since we don’t have to sit back the water, we don’t have to make use of evaporation. That’s enormous quantities of financial savings on the water. For us, it’s nearly like an ideal answer. It delivers the very best efficiency doable, the very best density doable, the bottom energy consumption. So, it’s essentially the most sustainable answer doable.”
So, how is the water cooled down? It will get piped as much as the roof, Tease says, the place there are big radiators with large quantities of floor space. The warmth radiates away, after which all of the water flows proper again to the servers once more.
Although not at all times. The recent water will also be used to, say, warmth campus or group swimming swimming pools. “Now we have knowledge facilities within the Nordics who’re giving the warmth to the native communities’ water methods,” Tease says.
