I have also worked with IBM 3080/3090 and ES9221 water cooled models of machines. IBM Mainframe machines were first launched into market as Water cooled models not Power 575 series.

Thanks.

Hi Graham

Thanks for the comment – I absolutely agree that liquid cooling is not new – hence the title of the article – “Back to the Future”. For scale up technology such as the mainframe and some HPC categories it is a great help in enabling high CPU clock rates. In addition being some 4000 times more capable of carrying heat, liquid uses significantly less energy that air to cool the same equipment.

For me this is both smart and obvious – who’s laughing now? No one.

“Unless I missed something in the article, the IBM Power 575 may be the most recent resurfacing of water cooled technology, the IBM 3090-600/600J and other System/390 boxes had water cooled technology in the late 1980s and early 1990s.”

… and before that there were the 3032 & 3033 in the late 70′s and the 308x’s in the early 80′s. At the time the competition scoffed at the idea.

[...] I recently had a conversation with Mark Anzani, IBM’s CTO for System z, the mainframe platform. Regular readers will know that cooling technology is a favourite subject here on the hot aisle and I was keen to get an answer to how IBM plan to cool their next range of machines, the z11 series.

Am I the last person to hear its going to be named the z11? RT @DynInfra: RT @anasbenmoussa: Back to the future -the z11 http://bit.ly/DFQDF

Gary,

You haven’t missed a thing. Hence the title “Back to the Future” – Mark made a pint of picking this out

Water cooling is the obvious answer to denser and denser systems.
