Iceotope Study with Meta Reveals Efficiency of Precision Immersion Liquid Cooling for High-Density Storage Drives
SHEFFIELD, United Kingdom, Nov. 30, 2022 (GLOBE NEWSWIRE) -- Iceotope, the global leader in precision immersion cooling, announces a new study with Meta confirming the practicality, efficiency and effectiveness of chassis-level liquid cooling technology to meet the cooling requirements of high-density storage disks increasingly being deployed and utilised by hyperscale data centre service providers.
The recently published study with Meta suggests the advantages of improved thermal management, reduced vibration and equalised temperature across the JBOD, which leads directly to lower failure rates and costs for data centre operators. The hard drive systems supplied in a rack form factor in chassis drawers are an ideal fit for precision immersion cooling technology.
Neil Edmunds, Director of Innovation, Iceotope, said: “As demand for data storage continues to escalate, so will the solutions needed by hyperscale data centre providers to efficiently cool the equipment. The study demonstrated that liquid cooling for high-density storage successfully cools the drives at a lower, more consistent temperature for fewer drive failures, lower TCO and improved ESG compliance.”
High-density storage proliferating
This presents a unique challenge for hyperscale data centre storage infrastructure. According to Seagate, cloud data centres choose mass-capacity hard disk drives (HDDs) to store 90% of their exabytes. Typically found in a 3.5-inch form factor, HDDs are a tried and tested technology which continues to offer data centre operators cost-effective torage 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 translates 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 not only improved disk performance with less drag but with the units now sealed, the practicality of using liquid cooling solutions at HDD level has been opened.
Meta study liquid cooling for high-density storage
The liquid cooling system tested was an Iceotope precision immersion liquid cooling system - the air-cooled version was modified with the addition of a dedicated dielectric loop connected to a liquid-to-liquid heat exchanger and pump. Meta proceeded to measure temperature variation across the hard drives and cooling pump power in the air-cooled and liquid-cooled systems.
The results are conclusive
While precision immersion is found to be a superior alternative to air-cooling high-density disk arrays, other forms of liquid cooling including cold plates, tank immersion, or two-phase immersion, don’t preserve the operational benefits such as HDD density, user access for serviceability and ability to hot swap drives to the same degree.
