IBM will begin shipping a computer with something that customers have not seen in a new mainframe from the company since 1995 -- water cooling. The new mainframe, dubbed the zEnterprise 196, can operate with up to 96 processors versus 64 in the System z10 mainframe using about the same amount of power. IBM credits the improved efficiency to an assortment of updates affecting how the new system uses its resources. Nonetheless, IBM saw fit to offer water cooling to help reduce overall data centre cooling needs.
Jim Porell, an IBM distinguished engineer said the optional water cooling system can improve overall environmental needs by about 12%, which may help some IT managers "squeeze the last piece of floor space in before they go buy a new data centre," said Porell.
