Back to the Future

Remember water-cooled mainframes?  Well, water is still among the best ways to cool large systems.  But now it makes more sense to cool systems with water as close to the heat as possible.  IBM has just announced a new Power Systems UNIX server, the Power 575, nicknamed "Hydro-Cluster," that pipes water to the chip itself, vastly reducing power and cooling requirements.

According to CNET, "A substantial part of the decrease in power consumption is due to a water cooling system that brings in chilled water from the outside, runs it through copper plates located above individual processors to absorb heat, and then draws the water out so it can expel the heat outside of the computer.

By getting rid of heat in this manner, the air conditioning requirements are greatly reduced for the "hydro cluster" 575. Air conditioning can account for roughly half of the power consumed by data centers. Conversely, instead of cutting electricity consumption, IBM, or one of its customers, could squeeze in more computing power into the same room and keep the air conditioning constant."

The new POWER6 "Hydro-Cluster" supercomputer, the Power 575, is designed to solve challenging problems in fields such as energy, aerospace and weather modeling. The  system is another breakthrough in green IT.  In addition to its advance water-cooling, it packs 448 processor cores per rack and delivers nearly five times the performance and more than three times the energy efficiency of its predecessor, IBM's POWER5+™ processor-based p575 supercomputer.
