Ibm Water Cooled Servers

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.

Ibm water cooled servers.

These were followed by the cmos system 390 mainframe family in the mid 1990s. 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. Ibm will license its technology for cooling servers with water instead of air to a chicago area company.

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. Z14 air cooled upgrades to ibm z15 water cooled z14 water cooled upgrades to ibm z15 water cooled. Heat removal to water can vary from 60 to 75 based on air inlet temperature water inlet temperature and fan speed. Water cooled servers have been around for more than a half a century.

Panduit a global networking and electrical manufacturer will license ibm s rear door heat. Ibm is just returning to water cooling servers after not using the technique since 1995. 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. Increased standardization of liquid cooled designs will help expand their use by.

Ibm researchers have delivered a data center breakthrough that could have a major impact on power consumption carbon. 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 flex system x240 compute node 8737 8738 7863 ibm flex system x440 compute node 7917 ibm nextscale nx360 m4 5455 ibm smart analytics system 7949 ibm system x idataplex direct water cooled dx360 m4 server 7918 7919 ibm system x idataplex dx320 server 7326 6388 ibm system x idataplex dx360 m2 server 7321 6380 7323.

In the past high performance mainframes were often water cooled and supplied as such by the ite manufacturer. Ibm s water cooled servers show off big wins in reducing power carbon.
