HP has made a clever upgrade to its Modular Cooling System (MCS) liquid-cooling rack. In its previous iteration, the unit was designed to chill a single rack packed with high-density machines. However, the company found that many customers weren't packing enough processing power into racks to take advantage of the MCS unit's full 35kW of cooling power. With the new G2 version, however, customers will have a way: With the new G2 version, however, customers will have a way: Thanks to bi-directional cooling technology (including three additional hot-swappable fans), MCS G2 can simultaneously cool two server racks at up to 17.5KW, or concentrate up to 35KW to cool a single rack. The machine’s form factor and power draw remain the same, however.HP says the water-cooled MCS reduces datacenter cooling costs by containing between 95 and 97 percent of heat inside server racks “while supporting up to three times the kilowatt capacity of a traditional, air-cooled rack.”More information is available at the HP site.
