Ibm Water Cooled Servers

The ibm system 390 was the third generation of the system 360 instruction set architecture the first esa 390 computer was the enterprise system 9000 es 9000 family which were introduced in 1990.

Ibm water cooled servers.

Heat removal to water can vary from 60 to 75 based on air inlet temperature water inlet temperature and fan speed. Ibm s water cooled servers show off big wins in reducing power carbon. Increased standardization of liquid cooled designs will help expand their use by. Your server configuration workload and server settings varies the amount of heat from the processor and the gpus that can be cooled by the water and the amount of cooling that is required for other components.

These systems were often highly customized and costly. Ibm researchers have delivered a data center breakthrough that could have a major impact on power consumption carbon. Ibm will license its technology for cooling servers with water instead of air to a chicago area company. Heat is removed from the system by circulating liquid into direct contact with hot components then through cool heat exchangers.

In the future ibm plans to introduce ptp as an external time source for ibm z server time protocol stp for an ibm z coordinated timing network ctn. Water cooled servers have been around for more than a half a century. Ibm is just returning to water cooling servers after not using the technique since 1995. In the past high performance mainframes were often water cooled and supplied as such by the ite manufacturer.

The initial implementation will be for ptp connectivity via the ibm z hmc se. Big blue abandoned water cooling after shipping its last bipolar mainframe with cmos complementary metal. Ibm s water cooled system reduces server heat output in data centers by up to 55 compared to air cooled technology said tom bradicich cto for ibm s bladecenter and system x server product lines.

These were followed by the cmos system 390 mainframe family in the mid 1990s. Immersion cooling is an it cooling practice by which it components and other electronics including complete servers are submerged in a thermally conductive dielectric liquid or coolant.
