Iceotope Reveals Efficiency of Liquid Cooling for Storage Drives

Iceotope, a leader in precision immersion cooling, announced findings from a study with Meta confirming the practicality, efficiency and effectiveness of chassis-level liquid cooling  to meet the requirements of high-density storage disks being deployed and used by hyperscale data center service providers.

The study suggests the advantages of improved thermal management, reduced vibration and equalized temperature across the JBOD, which leads directly to lower failure rates and costs for data center operators. The hard drive systems supplied in a rack form factor in chassis drawers are an ideal fit for precision immersion cooling technology.

With constant streams of data emerging from the Internet of Things (IoT, video, artificial intelligence and more, up to 463 exabytes of data are expected to be generated by each person, each day by 2025. How data are accessed and interacted changes constantly, causing an impact on the processing and storage of that data. It’s predicted that global data storage will exceed 200 zettabytes in a few years. More than half of the data are expected to be stored in the cloud.

This presents a challenge for hyperscale data center storage infrastructure. According to Seagate, cloud data centers choose mass-capacity hard disk drives (HDDs) to store 90 percent of their exabytes. Typically found in a 3.5-inch form factor, HDDs are tested technology that offer data center operators cost-effective storage at scale. Current top-of-the-range units provide 20 TB capacity, but this is expected to reach >120TB by the end of the decade.

More data storage means more spinning disks, higher-speed motors, and more actuators – all of which translate into more power being used. As disks go up in power, so does the amount of heat they produce. The introduction of helium into hard drive enclosures over the last decade has improved disk performance with less drag and has shown the practicality of using liquid cooling solutions at the HDD level.
